But certain frame or wheel shapes can actually harness this wind, utilising the &#8216;sail effect&#8217; to generate forward propulsion, in the same way an aircraft&#8217;s wings generate upward lift, to make you faster.<\/p>\n<p id=\"1b18887f-b6ff-4d05-b807-459335e884f1-2\" class=\"paywall\" aria-hidden=\"true\">The angle at which the wind hits the rider is called the yaw angle, taking into account where the wind is coming from and also your speed.<\/p>\n<p><span class=\"article-continues-below block py-2 text-sm\">Article continues below <\/span><\/p>\n<aside data-component-name=\"Recirculation:ArticleRiver\" data-recirculation-type=\"inline\" data-mrf-recirculation=\"Trending Bar\" data-nosnippet class=\"clear-both pb-0 pt-2 mb-4\"><span class=\"\n            flex\n            after:content-[''] after:flex-1 after:ml-4 after:my-[0.7rem] after:border-t after:border-solid after:border-t-[#ccc]\n            before:content-[''] before:flex-1 before:mr-4 before:my-[0.7rem] before:border-t before:border-solid before:border-t-[#ccc]\n            font-article-heading pb-0 !text-base uppercase sm:text-sm font-bold\n        \"><br \/>\n            You may like<br \/>\n        <\/span><\/p>\n<ul class=\"flex flex-col gap-0 m-0\">\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-1\" data-analytics-id=\"recirculation-inline-1\" data-mrf-recirculation=\"recirculation-inline-1\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/zwV5AqqqN6oe5fLsdkMaQ3-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/zwV5AqqqN6oe5fLsdkMaQ3-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: Can the four-year-old Enve Melee stay relevant in a hyper-aero landscape?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-2\" data-analytics-id=\"recirculation-inline-2\" data-mrf-recirculation=\"recirculation-inline-2\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/HcQv8ZnxqkCRk49D2oGRxG-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/HcQv8ZnxqkCRk49D2oGRxG-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: How does the new Cannondale SuperSix Evo compare to its superbike rivals&#8230; and the old one?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ccc] py-2\" data-recirculation-id=\"recirculation-card-3\" data-analytics-id=\"recirculation-inline-3\" data-mrf-recirculation=\"recirculation-inline-3\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Best road bike wheels 2026: Aero options tested for a faster ride<\/span><\/li>\n<\/ul>\n<\/aside>\n<p class=\"paywall\" aria-hidden=\"true\">When it comes to the aerodynamic performance of bikes and wheels, there is a lot more going on than just head-on, zero-degree-yaw performance.<\/p>\n<p>When riding out on the road, we very rarely experience true 0\u00b0 yaw, which is the equivalent of a dead-on headwind. Track riders, on the contrary, will experience 0\u00b0 yaw a lot more often.<\/p>\n<p class=\"paywall\" aria-hidden=\"true\">This is why, when bike brands are testing bikes, wheels, or any other aerodynamic piece of equipment, they test it at multiple yaw angles.<\/p>\n<p>Our <u><em>Cyclingnews<\/em><\/u><u> Labs<\/u> tests of bikes, wheels, helmets, aero socks and other equipment in the wind tunnel have all used a range of yaw angles, going from -15\u00b0 to 0\u00b0 to 15\u00b0, in steps of 5\u00b0. It\u2019s important that we measure this, as something that is fastest at 0\u00b0 might not be as fast across all the other measurements, and therefore, in the real world, might not be that effective.<\/p>\n<div id=\"slice-container-newsletterForm-articleInbodyContent-7pAFQcXK4mFjC42hNYiRQD\" class=\"slice-container newsletter-inbodyContent-slice newsletterForm-articleInbodyContent-7pAFQcXK4mFjC42hNYiRQD slice-container-newsletterForm\">\n<div data-hydrate=\"true\" class=\"newsletter-form__wrapper newsletter-form__wrapper--inbodyContent\">\n<div class=\"newsletter-form__container\">\n<section class=\"newsletter-form__top-bar\">\n<div class=\"newsletter-form__header\">Get The Leadout Newsletter<\/div>\n<\/section>\n<section class=\"newsletter-form__main-section\">\n<p class=\"newsletter-form__strapline\">The latest race content, interviews, features, reviews and expert buying guides, direct to your inbox!<\/p>\n<footer class=\"newsletter-form__footer \">By submitting your information you agree to the Terms &amp; Conditions and Privacy Policy and are aged 16 or over.<\/footer>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"paywall\" aria-hidden=\"true\">The sail effect is something that gets mentioned a lot when it comes to aerodynamic testing and performance, and we even saw in some of our testing that higher yaw angles resulted in lower drag. Here, we will look at what exactly the sail effect is, how it works, and most importantly, whether it&#8217;s going to make you faster or not.<\/p>\n<h2 id=\"the-impact-of-sailing-3\">The impact of &#8216;sailing&#8217;<\/h2>\n<p id=\"7696bf36-c70f-42f9-aded-ea6b9cb461ff\">Much like a nautical sail, the sail effect happens when wind coming at the bike from an angle actually reduces the coefficient of drag relative to the 0\u00b0 yaw measurement by generating thrust, which, in a nutshell, can help us go faster.<\/p>\n<p>You can see in some of our bike-only testing that one frame stood out as generating a sail effect as yaw angles increased, and actually became faster at higher yaw angles (more crosswind-y). This happens mainly due to the deeper frame tube profiles being used on some of these bikes, as there is more of an effective \u2018sail\u2019 provided by them. Deeper headtube and bottom bracket clusters can also assist this, as well as deeper seatposts.<\/p>\n<aside data-component-name=\"Recirculation:ArticleRiver\" data-recirculation-type=\"inline\" data-mrf-recirculation=\"Trending Bar\" data-nosnippet class=\"clear-both pb-0 pt-2 mb-4\"><span class=\"\n            flex\n            after:content-[''] after:flex-1 after:ml-4 after:my-[0.7rem] after:border-t after:border-solid after:border-t-[#ccc]\n            before:content-[''] before:flex-1 before:mr-4 before:my-[0.7rem] before:border-t before:border-solid before:border-t-[#ccc]\n            font-article-heading pb-0 !text-base uppercase sm:text-sm font-bold\n        \"><br \/>\n            What to read next<br \/>\n        <\/span><\/p>\n<ul class=\"flex flex-col gap-0 m-0\">\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-1\" data-analytics-id=\"recirculation-2-inline-1\" data-mrf-recirculation=\"recirculation-2-inline-1\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/TBBQZuEFc4yfWcA6Qp8ADL-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/TBBQZuEFc4yfWcA6Qp8ADL-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">More aero but slower rolling; does the Continental Aero 111 front tyre actually make you faster? <\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-2\" data-analytics-id=\"recirculation-2-inline-2\" data-mrf-recirculation=\"recirculation-2-inline-2\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: Is the Wilier Filante SLR ID2 really &#8216;the fastest in the WorldTour landscape&#8217;?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ccc] py-2\" data-recirculation-id=\"recirculation-card-3\" data-analytics-id=\"recirculation-2-inline-3\" data-mrf-recirculation=\"recirculation-2-inline-3\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/5mRzxYvjfyLPxZ4cuDu5He-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/5mRzxYvjfyLPxZ4cuDu5He-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Cinelli claims its new Aeroscoop is &#8216;faster than a Tarmac SL8&#8217; but we&#8217;ve checked and it isn&#8217;t even close<\/span><\/li>\n<\/ul>\n<\/aside>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"201347ef-b49f-45d8-9153-a115ec566f98\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-1200-80.png.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-1024-80.png.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-970-80.png.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-650-80.png.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-480-80.png.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-320-80.png.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">The Green &#8216;Aerofoil Lift&#8217; arrow shows how the effective wind vector can generate a forwards force on the frame to counter the &#8216;Aerofoil Drag&#8217; rearwards force. <\/span><span class=\"credit\">(Image credit: ScienceDirect &#8211; Barry et al., 2012)<\/span><\/figcaption><\/figure>\n<p id=\"0dce4225-0a9c-4900-afa1-785c09ede595\">As the air approaches the frame the side, the airflow can then generate a side force that partially offsets aerodynamic drag. We can see in our <u>own wind tunnel bike tests<\/u> that on some bikes, the Factor ONE in this instance, the frame actually has lower drag at 15\u02da and -15\u02da Yaw than at 0\u02da. The results change when a rider is placed on the bike, but the performance is still greater at higher Yaw angles relative to, for example, how the Trek Emonda (our old reference machine) performs at them.<\/p>\n<p>The drop in sail effect when a rider is placed on the bike happens because once we put a rider on the bike and have the wind coming from an angle, there is a larger area of effectively moving parts across that plane of motion. A rider&#8217;s body and legs are notoriously un-aerodynamic. This is where aerodynamic clothing comes into play to reduce drag on those areas.<\/p>\n<p>Rule28 also created a (UCI illegal) WingSuit back in 2020 that resembled a flying squirrel with fabric between the elbows and waist to create an actual sail that was significantly faster at higher yaw angles.<\/p>\n<div id=\"slice-container-imageGallery-7pAFQcXK4mFjC42hNYiRQD-9rIrILgaPss1lVEk2xGYb4D6rhAzmB3I\" class=\"slice-container imageGallery-wrapper imageGallery-7pAFQcXK4mFjC42hNYiRQD-9rIrILgaPss1lVEk2xGYb4D6rhAzmB3I slice-container-imageGallery\">\n<div data-hydrate=\"true\" class=\"inline-gallery first-slide-only\">\n<div class=\"inline-gallery__count\">Image 1 of 2<\/div>\n<div class=\"inline-gallery__items\">\n<div class=\"react-swipeable-view-container\">\n<div aria-hidden=\"false\" data-swipeable=\"true\">\n<div class=\"items__item\">\n<div class=\"item__image-cont\">\n<div class=\"image-cont__image\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-320-80.png.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-480-80.png.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-650-80.png.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-970-80.png.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-1024-80.png.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-1200-80.png.webp 1200w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" data-normal=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV.png\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV.png\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV.png\" data-pin-nopin=\"true\" data-slice-image=\"true\" \/><\/div>\n<\/div>\n<\/div><figcaption class=\"caption-credit__figcaption\"><span class=\"caption-credit__caption\">The shape of the tubing on the bikes can have a large impact on the sail potential <\/span><span class=\"caption-credit__credit\">(Image credit: Will Jones)<\/span><\/figcaption><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div aria-hidden=\"true\" data-swipeable=\"true\">\n<div class=\"items__item\">\n<div class=\"item__image-cont\">\n<div class=\"image-cont__image\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-320-80.jpg.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-1200-80.jpg.webp 1200w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" data-normal=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7.jpg\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7.jpg\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7.jpg\" data-pin-nopin=\"true\" data-slice-image=\"true\" \/><\/div>\n<\/div>\n<\/div><figcaption class=\"caption-credit__figcaption\"><span class=\"caption-credit__caption\">However, adding big moving legs on either side impacts the flow of air dramatically and can alter the sail effect significantly <\/span><span class=\"caption-credit__credit\">(Image credit: Will Jones)<\/span><\/figcaption><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p id=\"aceb11dc-e230-4ebd-b860-114247b9be18\">If we look at the sail effect of just the Factor One frame, and extrapolate that into 40k TT performance when travelling at 40kph, it is interesting to see that a frame with this sail effect might actually be 47 seconds and 0.5kph faster with an effective yaw experienced of 15\u00b0.<\/p>\n<p>Likewise, in our <u>wind tunnel wheel test<\/u>, we saw that often, wheels had a lower CdA at yaw angles of 15\u00b0 or -15\u00b0 than at 5\u00b0 or -5\u00b0.<\/p>\n<p>Looking at the Scope Artech 6A wheel, for example, the difference between 0\u00b0 and -15\u00b0 Yaw was equivalent to a saving of 3 minutes 54 seconds over 40km, or 2.8kph, in favour of -15\u00b0.<\/p>\n<p>Of course, it&#8217;s rare that anyone will experience 15\u00b0 &#8211; or indeed any single yaw angle &#8211; for an extended period of time. The very nature of, well, nature is that wind speed will constantly be changing, as will its direction. This is why a bike that can perform well across all wind angles should outperform a bike that is fast only at 0\u00b0, assuming all else is equal, of course.<\/p>\n<h2 id=\"wheels-3\">Wheels<\/h2>\n<div id=\"slice-container-imageGallery-7pAFQcXK4mFjC42hNYiRQD-PIPBMIRIZHCKJ79imGuwZHl3zia9nSNI\" class=\"slice-container imageGallery-wrapper imageGallery-7pAFQcXK4mFjC42hNYiRQD-PIPBMIRIZHCKJ79imGuwZHl3zia9nSNI slice-container-imageGallery\">\n<div data-hydrate=\"true\" class=\"inline-gallery first-slide-only\">\n<div class=\"inline-gallery__count\">Image 1 of 3<\/div>\n<div class=\"inline-gallery__items\">\n<div class=\"react-swipeable-view-container\">\n<div aria-hidden=\"false\" data-swipeable=\"true\">\n<div class=\"items__item\">\n<div class=\"item__image-cont\">\n<div class=\"image-cont__image\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-320-80.jpg.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-1200-80.jpg.webp 1200w\" sizes=\"(min-width: 1000px) 970px, calc(100vw -

Disc wheels are generally reserved for triathlon, time trials and track events, but their impact on the sail effect can be huge.<\/p>\n<p>As part of my coaching and aerodynamics consulting business, I conduct quite a lot of wind tunnel testing on time triallists and triathletes, and when we test across different yaw angles, a disc wheel almost always results in lower drag for the same speed as the wind angle increases.<\/p>\n<p>This happens because the disc works as a wonderfully effective sail. It is also why, even with the extra weight compared to a trispoke or a traditional spoked wheel, a disc wheel is often a very smart option even for something like a mountain TT.<\/p>\n<p>We saw at the 2025 Tour de France the use of disc wheels by riders on the <u>mountain TT stage<\/u>. In part, this is because the aero savings outweighed &#8211; literally &#8211; the added weight. But the nature of this time trial also unveiled another area where disc wheels can actually perform relatively better.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"4ab6a3fe-0bfc-4f5f-9cfa-1cc8e03cbbf9\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-1024-80.jpg.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-320-80.jpg.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">Sail performance makes a huge difference in the real world, where the wind can come from higher yaw angles than 0-5\u02da <\/span><span class=\"credit\">(Image credit: Getty Images)<\/span><\/figcaption><\/figure>\n<h2 id=\"higher-speed-lower-yaw-3\">Higher speed = lower yaw<\/h2>\n<p id=\"91203435-7342-498e-ad90-eff01a96a1dc\">Yaw angle is not only about the speed and direction of the wind, but how they combine with the speed and direction of you on the bike. For example, if you travel at 30km\/h with a wind of 10km\/h coming at you from a 10\u00b0 angle, the effective yaw is only 2.5\u00b0. If you are travelling at 50km\/h, the effective yaw angle decreases to 1.7\u00b0.<\/p>\n<p>So the faster you go, the lower the yaw angle will be in the same wind conditions. And the slower the wind speed, the lower the yaw will be.<\/p>\n<p>This is why disc wheels can actually be even more advantageous when travelling at slower speeds, such as in the above case of an uphill time trial, since riders might be more susceptible to greater sail impacts due to higher potential yaw angles.<\/p>\n<p>This means there are bigger gains to be made by amateurs, given our slower speeds, than there are for pros. We can\u2019t ride rear disc wheels everywhere, but where safe to do so, deeper-section wide rim wheels can still be more susceptible to sail effects in crosswinds than shallower options. Just be careful not to use them on too blustery days, where they can also negatively affect your handling.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"1438668b-4e43-42ee-845e-cd350c3045b5\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-1200-80.jpg.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-320-80.jpg.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">Testing a lot of wheels in the wind tunnel showed some interesting results as yaw and speed changed <\/span><span class=\"credit\">(Image credit: Cyclingnews)<\/span><\/figcaption><\/figure>\n<p id=\"039a11e7-3331-404c-88b6-e95c9d236c00\">As a little side note, very rarely do brands test at angles as extreme as 20\u00b0 yaw. This is because, even at a rider speed of 30km\/h, for the yaw angle to be 20\u00b0, a 20km\/h wind has to be coming at you at an angle of 51\u00b0.<\/p>\n<p>If that wind is just 10kph, the required angle actually becomes unachievable since it is more than 90\u00b0, so a cross-tailwind. And given most aero-focussed products are developed for racers, they are often designed to be ridden at much higher speeds where the likelihood of experiencing 20\u00b0 or more is vanishingly small.<\/p>\n<p>In reality, yaw angles such as 20\u00b0 or more are unlikely to be experienced by a rider, so it is not really worth testing at those levels.<\/p>\n<p>It is sometimes used to create headline-grabbing marketing claims, but that&#8217;s a complaint for another day!<\/p>\n<\/div>\n<div class=\"block\" id=\"articleTag\" data-component-name=\"PostArticleLinks\" data-nosnippet data-mrf-recirculation=\"post-article-links\">\n<div class=\"border-b border-b-black border-solid py-2.5 text-black font-bold uppercase\">TOPICS<\/div>\n<nav class=\"py-2.5 flex gap-2.5 flex-wrap\" data-analytics-id=\"article-tag\" data-mrf-recirculation=\"article-tag\">\n<p>Tech<\/p>\n<p>Road<\/p>\n<\/nav>\n<\/div>\n<div id=\"slice-container-authorBio-7pAFQcXK4mFjC42hNYiRQD\" class=\"slice-container slice-author-bio authorBio-7pAFQcXK4mFjC42hNYiRQD slice-container-authorBio\">\n<div class=\"author author__default-layout author--separator author--collapsible\" data-hydrate=\"true\">\n<div class=\"author__header\">\n<div class=\"author__avatar-block\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"author__avatar image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL-140-80.jpg.webp 140w\" sizes=\"99vw\" data-normal=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL.jpg\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL.jpg\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL.jpg\" data-pin-nopin=\"true\" data-slice-image=\"true\" \/><\/div>\n<\/div>\n<\/div>\n<\/figure>\n<\/div>\n<div class=\"author__heading\">\n<div class=\"author__name\">Andy Turner<\/div>\n<div class=\"author__social\">\n<nav class=\"button-social-group author__social-buttons\" aria-labelledby=\"button-social-group- author__social-buttons\">\n<div id=\"button-social-group- author__social-buttons\">Social Links Navigation<\/div>\n<\/nav>\n<\/div>\n<div class=\"author__role\">Freelance writer<\/div>\n<\/div>\n<\/div>\n<div class=\"author__bio-wrapper\">\n<div class=\"author__biography\">\n<p>Freelance cycling journalist Andy Turner is a fully qualified sports scientist, cycling coach at ATP Performance, and aerodynamics consultant at Venturi Dynamics.

But certain frame or wheel shapes can actually harness this wind, utilising the &#8216;sail effect&#8217; to generate forward propulsion, in the same way an aircraft&#8217;s wings generate upward lift, to make you faster.<\/p>\n<p id=\"1b18887f-b6ff-4d05-b807-459335e884f1-2\" class=\"paywall\" aria-hidden=\"true\">The angle at which the wind hits the rider is called the yaw angle, taking into account where the wind is coming from and also your speed.<\/p>\n<p><span class=\"article-continues-below block py-2 text-sm\">Article continues below <\/span><\/p>\n<aside data-component-name=\"Recirculation:ArticleRiver\" data-recirculation-type=\"inline\" data-mrf-recirculation=\"Trending Bar\" data-nosnippet class=\"clear-both pb-0 pt-2 mb-4\"><span class=\"\n            flex\n            after:content-[''] after:flex-1 after:ml-4 after:my-[0.7rem] after:border-t after:border-solid after:border-t-[#ccc]\n            before:content-[''] before:flex-1 before:mr-4 before:my-[0.7rem] before:border-t before:border-solid before:border-t-[#ccc]\n            font-article-heading pb-0 !text-base uppercase sm:text-sm font-bold\n        \"><br \/>\n            You may like<br \/>\n        <\/span><\/p>\n<ul class=\"flex flex-col gap-0 m-0\">\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-1\" data-analytics-id=\"recirculation-inline-1\" data-mrf-recirculation=\"recirculation-inline-1\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/zwV5AqqqN6oe5fLsdkMaQ3-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/zwV5AqqqN6oe5fLsdkMaQ3-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: Can the four-year-old Enve Melee stay relevant in a hyper-aero landscape?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-2\" data-analytics-id=\"recirculation-inline-2\" data-mrf-recirculation=\"recirculation-inline-2\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/HcQv8ZnxqkCRk49D2oGRxG-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/HcQv8ZnxqkCRk49D2oGRxG-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: How does the new Cannondale SuperSix Evo compare to its superbike rivals&#8230; and the old one?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ccc] py-2\" data-recirculation-id=\"recirculation-card-3\" data-analytics-id=\"recirculation-inline-3\" data-mrf-recirculation=\"recirculation-inline-3\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Best road bike wheels 2026: Aero options tested for a faster ride<\/span><\/li>\n<\/ul>\n<\/aside>\n<p class=\"paywall\" aria-hidden=\"true\">When it comes to the aerodynamic performance of bikes and wheels, there is a lot more going on than just head-on, zero-degree-yaw performance.<\/p>\n<p>When riding out on the road, we very rarely experience true 0\u00b0 yaw, which is the equivalent of a dead-on headwind. Track riders, on the contrary, will experience 0\u00b0 yaw a lot more often.<\/p>\n<p class=\"paywall\" aria-hidden=\"true\">This is why, when bike brands are testing bikes, wheels, or any other aerodynamic piece of equipment, they test it at multiple yaw angles.<\/p>\n<p>Our <u><em>Cyclingnews<\/em><\/u><u> Labs<\/u> tests of bikes, wheels, helmets, aero socks and other equipment in the wind tunnel have all used a range of yaw angles, going from -15\u00b0 to 0\u00b0 to 15\u00b0, in steps of 5\u00b0. It\u2019s important that we measure this, as something that is fastest at 0\u00b0 might not be as fast across all the other measurements, and therefore, in the real world, might not be that effective.<\/p>\n<div id=\"slice-container-newsletterForm-articleInbodyContent-7pAFQcXK4mFjC42hNYiRQD\" class=\"slice-container newsletter-inbodyContent-slice newsletterForm-articleInbodyContent-7pAFQcXK4mFjC42hNYiRQD slice-container-newsletterForm\">\n<div data-hydrate=\"true\" class=\"newsletter-form__wrapper newsletter-form__wrapper--inbodyContent\">\n<div class=\"newsletter-form__container\">\n<section class=\"newsletter-form__top-bar\">\n<div class=\"newsletter-form__header\">Get The Leadout Newsletter<\/div>\n<\/section>\n<section class=\"newsletter-form__main-section\">\n<p class=\"newsletter-form__strapline\">The latest race content, interviews, features, reviews and expert buying guides, direct to your inbox!<\/p>\n<footer class=\"newsletter-form__footer \">By submitting your information you agree to the Terms &amp; Conditions and Privacy Policy and are aged 16 or over.<\/footer>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"paywall\" aria-hidden=\"true\">The sail effect is something that gets mentioned a lot when it comes to aerodynamic testing and performance, and we even saw in some of our testing that higher yaw angles resulted in lower drag. Here, we will look at what exactly the sail effect is, how it works, and most importantly, whether it&#8217;s going to make you faster or not.<\/p>\n<h2 id=\"the-impact-of-sailing-3\">The impact of &#8216;sailing&#8217;<\/h2>\n<p id=\"7696bf36-c70f-42f9-aded-ea6b9cb461ff\">Much like a nautical sail, the sail effect happens when wind coming at the bike from an angle actually reduces the coefficient of drag relative to the 0\u00b0 yaw measurement by generating thrust, which, in a nutshell, can help us go faster.<\/p>\n<p>You can see in some of our bike-only testing that one frame stood out as generating a sail effect as yaw angles increased, and actually became faster at higher yaw angles (more crosswind-y). This happens mainly due to the deeper frame tube profiles being used on some of these bikes, as there is more of an effective \u2018sail\u2019 provided by them. Deeper headtube and bottom bracket clusters can also assist this, as well as deeper seatposts.<\/p>\n<aside data-component-name=\"Recirculation:ArticleRiver\" data-recirculation-type=\"inline\" data-mrf-recirculation=\"Trending Bar\" data-nosnippet class=\"clear-both pb-0 pt-2 mb-4\"><span class=\"\n            flex\n            after:content-[''] after:flex-1 after:ml-4 after:my-[0.7rem] after:border-t after:border-solid after:border-t-[#ccc]\n            before:content-[''] before:flex-1 before:mr-4 before:my-[0.7rem] before:border-t before:border-solid before:border-t-[#ccc]\n            font-article-heading pb-0 !text-base uppercase sm:text-sm font-bold\n        \"><br \/>\n            What to read next<br \/>\n        <\/span><\/p>\n<ul class=\"flex flex-col gap-0 m-0\">\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-1\" data-analytics-id=\"recirculation-2-inline-1\" data-mrf-recirculation=\"recirculation-2-inline-1\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/TBBQZuEFc4yfWcA6Qp8ADL-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/TBBQZuEFc4yfWcA6Qp8ADL-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">More aero but slower rolling; does the Continental Aero 111 front tyre actually make you faster? <\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-2\" data-analytics-id=\"recirculation-2-inline-2\" data-mrf-recirculation=\"recirculation-2-inline-2\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: Is the Wilier Filante SLR ID2 really &#8216;the fastest in the WorldTour landscape&#8217;?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ccc] py-2\" data-recirculation-id=\"recirculation-card-3\" data-analytics-id=\"recirculation-2-inline-3\" data-mrf-recirculation=\"recirculation-2-inline-3\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/5mRzxYvjfyLPxZ4cuDu5He-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/5mRzxYvjfyLPxZ4cuDu5He-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Cinelli claims its new Aeroscoop is &#8216;faster than a Tarmac SL8&#8217; but we&#8217;ve checked and it isn&#8217;t even close<\/span><\/li>\n<\/ul>\n<\/aside>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"201347ef-b49f-45d8-9153-a115ec566f98\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-1200-80.png.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-1024-80.png.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-970-80.png.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-650-80.png.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-480-80.png.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-320-80.png.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">The Green &#8216;Aerofoil Lift&#8217; arrow shows how the effective wind vector can generate a forwards force on the frame to counter the &#8216;Aerofoil Drag&#8217; rearwards force. <\/span><span class=\"credit\">(Image credit: ScienceDirect &#8211; Barry et al., 2012)<\/span><\/figcaption><\/figure>\n<p id=\"0dce4225-0a9c-4900-afa1-785c09ede595\">As the air approaches the frame the side, the airflow can then generate a side force that partially offsets aerodynamic drag. We can see in our <u>own wind tunnel bike tests<\/u> that on some bikes, the Factor ONE in this instance, the frame actually has lower drag at 15\u02da and -15\u02da Yaw than at 0\u02da. The results change when a rider is placed on the bike, but the performance is still greater at higher Yaw angles relative to, for example, how the Trek Emonda (our old reference machine) performs at them.<\/p>\n<p>The drop in sail effect when a rider is placed on the bike happens because once we put a rider on the bike and have the wind coming from an angle, there is a larger area of effectively moving parts across that plane of motion. A rider&#8217;s body and legs are notoriously un-aerodynamic. This is where aerodynamic clothing comes into play to reduce drag on those areas.<\/p>\n<p>Rule28 also created a (UCI illegal) WingSuit back in 2020 that resembled a flying squirrel with fabric between the elbows and waist to create an actual sail that was significantly faster at higher yaw angles.<\/p>\n<div id=\"slice-container-imageGallery-7pAFQcXK4mFjC42hNYiRQD-9rIrILgaPss1lVEk2xGYb4D6rhAzmB3I\" class=\"slice-container imageGallery-wrapper imageGallery-7pAFQcXK4mFjC42hNYiRQD-9rIrILgaPss1lVEk2xGYb4D6rhAzmB3I slice-container-imageGallery\">\n<div data-hydrate=\"true\" class=\"inline-gallery first-slide-only\">\n<div class=\"inline-gallery__count\">Image 1 of 2<\/div>\n<div class=\"inline-gallery__items\">\n<div class=\"react-swipeable-view-container\">\n<div aria-hidden=\"false\" data-swipeable=\"true\">\n<div class=\"items__item\">\n<div class=\"item__image-cont\">\n<div class=\"image-cont__image\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-320-80.png.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-480-80.png.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-650-80.png.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-970-80.png.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-1024-80.png.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV-1200-80.png.webp 1200w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" data-normal=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV.png\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV.png\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/TTJJmCfAikfriLYhSQ3hSV.png\" data-pin-nopin=\"true\" data-slice-image=\"true\" \/><\/div>\n<\/div>\n<\/div><figcaption class=\"caption-credit__figcaption\"><span class=\"caption-credit__caption\">The shape of the tubing on the bikes can have a large impact on the sail potential <\/span><span class=\"caption-credit__credit\">(Image credit: Will Jones)<\/span><\/figcaption><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div aria-hidden=\"true\" data-swipeable=\"true\">\n<div class=\"items__item\">\n<div class=\"item__image-cont\">\n<div class=\"image-cont__image\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-320-80.jpg.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-1200-80.jpg.webp 1200w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" data-normal=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7.jpg\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7.jpg\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7.jpg\" data-pin-nopin=\"true\" data-slice-image=\"true\" \/><\/div>\n<\/div>\n<\/div><figcaption class=\"caption-credit__figcaption\"><span class=\"caption-credit__caption\">However, adding big moving legs on either side impacts the flow of air dramatically and can alter the sail effect significantly <\/span><span class=\"caption-credit__credit\">(Image credit: Will Jones)<\/span><\/figcaption><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p id=\"aceb11dc-e230-4ebd-b860-114247b9be18\">If we look at the sail effect of just the Factor One frame, and extrapolate that into 40k TT performance when travelling at 40kph, it is interesting to see that a frame with this sail effect might actually be 47 seconds and 0.5kph faster with an effective yaw experienced of 15\u00b0.<\/p>\n<p>Likewise, in our <u>wind tunnel wheel test<\/u>, we saw that often, wheels had a lower CdA at yaw angles of 15\u00b0 or -15\u00b0 than at 5\u00b0 or -5\u00b0.<\/p>\n<p>Looking at the Scope Artech 6A wheel, for example, the difference between 0\u00b0 and -15\u00b0 Yaw was equivalent to a saving of 3 minutes 54 seconds over 40km, or 2.8kph, in favour of -15\u00b0.<\/p>\n<p>Of course, it&#8217;s rare that anyone will experience 15\u00b0 &#8211; or indeed any single yaw angle &#8211; for an extended period of time. The very nature of, well, nature is that wind speed will constantly be changing, as will its direction. This is why a bike that can perform well across all wind angles should outperform a bike that is fast only at 0\u00b0, assuming all else is equal, of course.<\/p>\n<h2 id=\"wheels-3\">Wheels<\/h2>\n<div id=\"slice-container-imageGallery-7pAFQcXK4mFjC42hNYiRQD-PIPBMIRIZHCKJ79imGuwZHl3zia9nSNI\" class=\"slice-container imageGallery-wrapper imageGallery-7pAFQcXK4mFjC42hNYiRQD-PIPBMIRIZHCKJ79imGuwZHl3zia9nSNI slice-container-imageGallery\">\n<div data-hydrate=\"true\" class=\"inline-gallery first-slide-only\">\n<div class=\"inline-gallery__count\">Image 1 of 3<\/div>\n<div class=\"inline-gallery__items\">\n<div class=\"react-swipeable-view-container\">\n<div aria-hidden=\"false\" data-swipeable=\"true\">\n<div class=\"items__item\">\n<div class=\"item__image-cont\">\n<div class=\"image-cont__image\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-320-80.jpg.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-1200-80.jpg.webp 1200w\" sizes=\"(min-width: 1000px) 970px, calc(100vw -

Disc wheels are generally reserved for triathlon, time trials and track events, but their impact on the sail effect can be huge.<\/p>\n<p>As part of my coaching and aerodynamics consulting business, I conduct quite a lot of wind tunnel testing on time triallists and triathletes, and when we test across different yaw angles, a disc wheel almost always results in lower drag for the same speed as the wind angle increases.<\/p>\n<p>This happens because the disc works as a wonderfully effective sail. It is also why, even with the extra weight compared to a trispoke or a traditional spoked wheel, a disc wheel is often a very smart option even for something like a mountain TT.<\/p>\n<p>We saw at the 2025 Tour de France the use of disc wheels by riders on the <u>mountain TT stage<\/u>. In part, this is because the aero savings outweighed &#8211; literally &#8211; the added weight. But the nature of this time trial also unveiled another area where disc wheels can actually perform relatively better.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"4ab6a3fe-0bfc-4f5f-9cfa-1cc8e03cbbf9\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-1024-80.jpg.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-320-80.jpg.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">Sail performance makes a huge difference in the real world, where the wind can come from higher yaw angles than 0-5\u02da <\/span><span class=\"credit\">(Image credit: Getty Images)<\/span><\/figcaption><\/figure>\n<h2 id=\"higher-speed-lower-yaw-3\">Higher speed = lower yaw<\/h2>\n<p id=\"91203435-7342-498e-ad90-eff01a96a1dc\">Yaw angle is not only about the speed and direction of the wind, but how they combine with the speed and direction of you on the bike. For example, if you travel at 30km\/h with a wind of 10km\/h coming at you from a 10\u00b0 angle, the effective yaw is only 2.5\u00b0. If you are travelling at 50km\/h, the effective yaw angle decreases to 1.7\u00b0.<\/p>\n<p>So the faster you go, the lower the yaw angle will be in the same wind conditions. And the slower the wind speed, the lower the yaw will be.<\/p>\n<p>This is why disc wheels can actually be even more advantageous when travelling at slower speeds, such as in the above case of an uphill time trial, since riders might be more susceptible to greater sail impacts due to higher potential yaw angles.<\/p>\n<p>This means there are bigger gains to be made by amateurs, given our slower speeds, than there are for pros. We can\u2019t ride rear disc wheels everywhere, but where safe to do so, deeper-section wide rim wheels can still be more susceptible to sail effects in crosswinds than shallower options. Just be careful not to use them on too blustery days, where they can also negatively affect your handling.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"1438668b-4e43-42ee-845e-cd350c3045b5\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-1200-80.jpg.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-320-80.jpg.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">Testing a lot of wheels in the wind tunnel showed some interesting results as yaw and speed changed <\/span><span class=\"credit\">(Image credit: Cyclingnews)<\/span><\/figcaption><\/figure>\n<p id=\"039a11e7-3331-404c-88b6-e95c9d236c00\">As a little side note, very rarely do brands test at angles as extreme as 20\u00b0 yaw. This is because, even at a rider speed of 30km\/h, for the yaw angle to be 20\u00b0, a 20km\/h wind has to be coming at you at an angle of 51\u00b0.<\/p>\n<p>If that wind is just 10kph, the required angle actually becomes unachievable since it is more than 90\u00b0, so a cross-tailwind. And given most aero-focussed products are developed for racers, they are often designed to be ridden at much higher speeds where the likelihood of experiencing 20\u00b0 or more is vanishingly small.<\/p>\n<p>In reality, yaw angles such as 20\u00b0 or more are unlikely to be experienced by a rider, so it is not really worth testing at those levels.<\/p>\n<p>It is sometimes used to create headline-grabbing marketing claims, but that&#8217;s a complaint for another day!<\/p>\n<\/div>\n<div class=\"block\" id=\"articleTag\" data-component-name=\"PostArticleLinks\" data-nosnippet data-mrf-recirculation=\"post-article-links\">\n<div class=\"border-b border-b-black border-solid py-2.5 text-black font-bold uppercase\">TOPICS<\/div>\n<nav class=\"py-2.5 flex gap-2.5 flex-wrap\" data-analytics-id=\"article-tag\" data-mrf-recirculation=\"article-tag\">\n<p>Tech<\/p>\n<p>Road<\/p>\n<\/nav>\n<\/div>\n<div id=\"slice-container-authorBio-7pAFQcXK4mFjC42hNYiRQD\" class=\"slice-container slice-author-bio authorBio-7pAFQcXK4mFjC42hNYiRQD slice-container-authorBio\">\n<div class=\"author author__default-layout author--separator author--collapsible\" data-hydrate=\"true\">\n<div class=\"author__header\">\n<div class=\"author__avatar-block\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"author__avatar image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL-140-80.jpg.webp 140w\" sizes=\"99vw\" data-normal=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL.jpg\" data-original-mos=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL.jpg\" data-pin-media=\"https:\/\/cdn.mos.cms.futurecdn.net\/J78VMEW7QNP4CgBtmf9SWL.jpg\" data-pin-nopin=\"true\" data-slice-image=\"true\" \/><\/div>\n<\/div>\n<\/div>\n<\/figure>\n<\/div>\n<div class=\"author__heading\">\n<div class=\"author__name\">Andy Turner<\/div>\n<div class=\"author__social\">\n<nav class=\"button-social-group author__social-buttons\" aria-labelledby=\"button-social-group- author__social-buttons\">\n<div id=\"button-social-group- author__social-buttons\">Social Links Navigation<\/div>\n<\/nav>\n<\/div>\n<div class=\"author__role\">Freelance writer<\/div>\n<\/div>\n<\/div>\n<div class=\"author__bio-wrapper\">\n<div class=\"author__biography\">\n<p>Freelance cycling journalist Andy Turner is a fully qualified sports scientist, cycling coach at ATP Performance, and aerodynamics consultant at Venturi Dynamics.

But certain frame or wheel shapes can actually harness this wind, utilising the &#8216;sail effect&#8217; to generate forward propulsion, in the same way an aircraft&#8217;s wings generate upward lift, to make you faster.<\/p>\n<p id=\"1b18887f-b6ff-4d05-b807-459335e884f1-2\" class=\"paywall\" aria-hidden=\"true\">The angle at which the wind hits the rider is called the yaw angle, taking into account where the wind is coming from and also your speed.<\/p>\n<p><span class=\"article-continues-below block py-2 text-sm\">Article continues below <\/span><\/p>\n<aside data-component-name=\"Recirculation:ArticleRiver\" data-recirculation-type=\"inline\" data-mrf-recirculation=\"Trending Bar\" data-nosnippet class=\"clear-both pb-0 pt-2 mb-4\"><span class=\"\n            flex\n            after:content-[''] after:flex-1 after:ml-4 after:my-[0.7rem] after:border-t after:border-solid after:border-t-[#ccc]\n            before:content-[''] before:flex-1 before:mr-4 before:my-[0.7rem] before:border-t before:border-solid before:border-t-[#ccc]\n            font-article-heading pb-0 !text-base uppercase sm:text-sm font-bold\n        \"><br \/>\n            You may like<br \/>\n        <\/span><\/p>\n<ul class=\"flex flex-col gap-0 m-0\">\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-1\" data-analytics-id=\"recirculation-inline-1\" data-mrf-recirculation=\"recirculation-inline-1\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/zwV5AqqqN6oe5fLsdkMaQ3-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/zwV5AqqqN6oe5fLsdkMaQ3-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: Can the four-year-old Enve Melee stay relevant in a hyper-aero landscape?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-2\" data-analytics-id=\"recirculation-inline-2\" data-mrf-recirculation=\"recirculation-inline-2\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/HcQv8ZnxqkCRk49D2oGRxG-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/HcQv8ZnxqkCRk49D2oGRxG-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: How does the new Cannondale SuperSix Evo compare to its superbike rivals&#8230; and the old one?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ccc] py-2\" data-recirculation-id=\"recirculation-card-3\" data-analytics-id=\"recirculation-inline-3\" data-mrf-recirculation=\"recirculation-inline-3\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Best road bike wheels 2026: Aero options tested for a faster ride<\/span><\/li>\n<\/ul>\n<\/aside>\n<p class=\"paywall\" aria-hidden=\"true\">When it comes to the aerodynamic performance of bikes and wheels, there is a lot more going on than just head-on, zero-degree-yaw performance.<\/p>\n<p>When riding out on the road, we very rarely experience true 0\u00b0 yaw, which is the equivalent of a dead-on headwind. Track riders, on the contrary, will experience 0\u00b0 yaw a lot more often.<\/p>\n<p class=\"paywall\" aria-hidden=\"true\">This is why, when bike brands are testing bikes, wheels, or any other aerodynamic piece of equipment, they test it at multiple yaw angles.<\/p>\n<p>Our <u><em>Cyclingnews<\/em><\/u><u> Labs<\/u> tests of bikes, wheels, helmets, aero socks and other equipment in the wind tunnel have all used a range of yaw angles, going from -15\u00b0 to 0\u00b0 to 15\u00b0, in steps of 5\u00b0. It\u2019s important that we measure this, as something that is fastest at 0\u00b0 might not be as fast across all the other measurements, and therefore, in the real world, might not be that effective.<\/p>\n<div id=\"slice-container-newsletterForm-articleInbodyContent-7pAFQcXK4mFjC42hNYiRQD\" class=\"slice-container newsletter-inbodyContent-slice newsletterForm-articleInbodyContent-7pAFQcXK4mFjC42hNYiRQD slice-container-newsletterForm\">\n<div data-hydrate=\"true\" class=\"newsletter-form__wrapper newsletter-form__wrapper--inbodyContent\">\n<div class=\"newsletter-form__container\">\n<section class=\"newsletter-form__top-bar\">\n<div class=\"newsletter-form__header\">Get The Leadout Newsletter<\/div>\n<\/section>\n<section class=\"newsletter-form__main-section\">\n<p class=\"newsletter-form__strapline\">The latest race content, interviews, features, reviews and expert buying guides, direct to your inbox!<\/p>\n<footer class=\"newsletter-form__footer \">By submitting your information you agree to the Terms &amp; Conditions and Privacy Policy and are aged 16 or over.<\/footer>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"paywall\" aria-hidden=\"true\">The sail effect is something that gets mentioned a lot when it comes to aerodynamic testing and performance, and we even saw in some of our testing that higher yaw angles resulted in lower drag. Here, we will look at what exactly the sail effect is, how it works, and most importantly, whether it&#8217;s going to make you faster or not.<\/p>\n<h2 id=\"the-impact-of-sailing-3\">The impact of &#8216;sailing&#8217;<\/h2>\n<p id=\"7696bf36-c70f-42f9-aded-ea6b9cb461ff\">Much like a nautical sail, the sail effect happens when wind coming at the bike from an angle actually reduces the coefficient of drag relative to the 0\u00b0 yaw measurement by generating thrust, which, in a nutshell, can help us go faster.<\/p>\n<p>You can see in some of our bike-only testing that one frame stood out as generating a sail effect as yaw angles increased, and actually became faster at higher yaw angles (more crosswind-y). This happens mainly due to the deeper frame tube profiles being used on some of these bikes, as there is more of an effective \u2018sail\u2019 provided by them. Deeper headtube and bottom bracket clusters can also assist this, as well as deeper seatposts.<\/p>\n<aside data-component-name=\"Recirculation:ArticleRiver\" data-recirculation-type=\"inline\" data-mrf-recirculation=\"Trending Bar\" data-nosnippet class=\"clear-both pb-0 pt-2 mb-4\"><span class=\"\n            flex\n            after:content-[''] after:flex-1 after:ml-4 after:my-[0.7rem] after:border-t after:border-solid after:border-t-[#ccc]\n            before:content-[''] before:flex-1 before:mr-4 before:my-[0.7rem] before:border-t before:border-solid before:border-t-[#ccc]\n            font-article-heading pb-0 !text-base uppercase sm:text-sm font-bold\n        \"><br \/>\n            What to read next<br \/>\n        <\/span><\/p>\n<ul class=\"flex flex-col gap-0 m-0\">\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-1\" data-analytics-id=\"recirculation-2-inline-1\" data-mrf-recirculation=\"recirculation-2-inline-1\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/TBBQZuEFc4yfWcA6Qp8ADL-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/TBBQZuEFc4yfWcA6Qp8ADL-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">More aero but slower rolling; does the Continental Aero 111 front tyre actually make you faster? <\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ededed] py-2\" data-recirculation-id=\"recirculation-card-2\" data-analytics-id=\"recirculation-2-inline-2\" data-mrf-recirculation=\"recirculation-2-inline-2\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/tHtKkwryBEpATRxmJVP5H7-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Wind tunnel tested: Is the Wilier Filante SLR ID2 really &#8216;the fastest in the WorldTour landscape&#8217;?<\/span><\/li>\n<li class=\"m-0 list-none border-b border-solid border-[#ccc] py-2\" data-recirculation-id=\"recirculation-card-3\" data-analytics-id=\"recirculation-2-inline-3\" data-mrf-recirculation=\"recirculation-2-inline-3\">\n    <source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/5mRzxYvjfyLPxZ4cuDu5He-250-80.jpg.webp 250w, https:\/\/cdn.mos.cms.futurecdn.net\/5mRzxYvjfyLPxZ4cuDu5He-150-80.jpg.webp 150w\" sizes=\"150px\" \/><span class=\"\n                            w-full font-article-heading line-clamp-3 md:line-clamp-2 text-base font-medium\">Cinelli claims its new Aeroscoop is &#8216;faster than a Tarmac SL8&#8217; but we&#8217;ve checked and it isn&#8217;t even close<\/span><\/li>\n<\/ul>\n<\/aside>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"201347ef-b49f-45d8-9153-a115ec566f98\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-1200-80.png.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-1024-80.png.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-970-80.png.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-650-80.png.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-480-80.png.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/t974ZjvDFZ6kaK5vqAAQHK-320-80.png.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">The Green &#8216;Aerofoil Lift&#8217; arrow shows how the effective wind vector can generate a forwards force on the frame to counter the &#8216;Aerofoil Drag&#8217; rearwards force. <\/span><span class=\"credit\">(Image credit: ScienceDirect &#8211; Barry et al., 2012)<\/span><\/figcaption><\/figure>\n<p id=\"0dce4225-0a9c-4900-afa1-785c09ede595\">As the air approaches the frame the side, the airflow can then generate a side force that partially offsets aerodynamic drag. We can see in our <u>own wind tunnel bike tests<\/u> that on some bikes, the Factor ONE in this instance, the frame actually has lower drag at 15\u02da and -15\u02da Yaw than at 0\u02da. The results change when a rider is placed on the bike, but the performance is still greater at higher Yaw angles relative to, for example, how the Trek Emonda (our old reference machine) performs at them.<\/p>\n<p>The drop in sail effect when a rider is placed on the bike happens because once we put a rider on the bike and have the wind coming from an angle, there is a larger area of effectively moving parts across that plane of motion. A rider&#8217;s body and legs are notoriously un-aerodynamic.

The very nature of, well, nature is that wind speed will constantly be changing, as will its direction. This is why a bike that can perform well across all wind angles should outperform a bike that is fast only at 0\u00b0, assuming all else is equal, of course.<\/p>\n<h2 id=\"wheels-3\">Wheels<\/h2>\n<div id=\"slice-container-imageGallery-7pAFQcXK4mFjC42hNYiRQD-PIPBMIRIZHCKJ79imGuwZHl3zia9nSNI\" class=\"slice-container imageGallery-wrapper imageGallery-7pAFQcXK4mFjC42hNYiRQD-PIPBMIRIZHCKJ79imGuwZHl3zia9nSNI slice-container-imageGallery\">\n<div data-hydrate=\"true\" class=\"inline-gallery first-slide-only\">\n<div class=\"inline-gallery__count\">Image 1 of 3<\/div>\n<div class=\"inline-gallery__items\">\n<div class=\"react-swipeable-view-container\">\n<div aria-hidden=\"false\" data-swipeable=\"true\">\n<div class=\"items__item\">\n<div class=\"item__image-cont\">\n<div class=\"image-cont__image\">\n<figure class=\"image-wrapped__wrapper\" data-bordeaux-image-check=\"false\">\n<div class=\"image-wrapped__widthsetter\">\n<div class=\"image-wrapped__aspect-padding\">\n<div><source class=\"image-wrapped__image image__image\" type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-320-80.jpg.webp 320w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/biTRzmDbkSRoRyjRZV79FE-1200-80.jpg.webp 1200w\" sizes=\"(min-width: 1000px) 970px, calc(100vw -

Disc wheels are generally reserved for triathlon, time trials and track events, but their impact on the sail effect can be huge.<\/p>\n<p>As part of my coaching and aerodynamics consulting business, I conduct quite a lot of wind tunnel testing on time triallists and triathletes, and when we test across different yaw angles, a disc wheel almost always results in lower drag for the same speed as the wind angle increases.<\/p>\n<p>This happens because the disc works as a wonderfully effective sail. It is also why, even with the extra weight compared to a trispoke or a traditional spoked wheel, a disc wheel is often a very smart option even for something like a mountain TT.<\/p>\n<p>We saw at the 2025 Tour de France the use of disc wheels by riders on the <u>mountain TT stage<\/u>. In part, this is because the aero savings outweighed &#8211; literally &#8211; the added weight. But the nature of this time trial also unveiled another area where disc wheels can actually perform relatively better.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"4ab6a3fe-0bfc-4f5f-9cfa-1cc8e03cbbf9\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-1024-80.jpg.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/zwoDHWzUjRwfwqXFwnYk68-320-80.jpg.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">Sail performance makes a huge difference in the real world, where the wind can come from higher yaw angles than 0-5\u02da <\/span><span class=\"credit\">(Image credit: Getty Images)<\/span><\/figcaption><\/figure>\n<h2 id=\"higher-speed-lower-yaw-3\">Higher speed = lower yaw<\/h2>\n<p id=\"91203435-7342-498e-ad90-eff01a96a1dc\">Yaw angle is not only about the speed and direction of the wind, but how they combine with the speed and direction of you on the bike. For example, if you travel at 30km\/h with a wind of 10km\/h coming at you from a 10\u00b0 angle, the effective yaw is only 2.5\u00b0. If you are travelling at 50km\/h, the effective yaw angle decreases to 1.7\u00b0.<\/p>\n<p>So the faster you go, the lower the yaw angle will be in the same wind conditions. And the slower the wind speed, the lower the yaw will be.<\/p>\n<p>This is why disc wheels can actually be even more advantageous when travelling at slower speeds, such as in the above case of an uphill time trial, since riders might be more susceptible to greater sail impacts due to higher potential yaw angles.<\/p>\n<p>This means there are bigger gains to be made by amateurs, given our slower speeds, than there are for pros. We can\u2019t ride rear disc wheels everywhere, but where safe to do so, deeper-section wide rim wheels can still be more susceptible to sail effects in crosswinds than shallower options. Just be careful not to use them on too blustery days, where they can also negatively affect your handling.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check id=\"1438668b-4e43-42ee-845e-cd350c3045b5\">\n<div class=\"image-full-width-wrapper\">\n<div class=\"image-widthsetter\">\n<p class=\"vanilla-image-block\">\n<source type=\"image\/webp\" srcset=\"https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-1200-80.jpg.webp 1200w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-1024-80.jpg.webp 1024w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-970-80.jpg.webp 970w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-650-80.jpg.webp 650w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-480-80.jpg.webp 480w, https:\/\/cdn.mos.cms.futurecdn.net\/CuYuafke72rpUKKWwoZw8X-320-80.jpg.webp 320w\" sizes=\"(min-width: 1000px) 970px, calc(100vw - 40px)\" \/><\/p>\n<\/div>\n<\/div><figcaption class=\" inline-layout\"><span class=\"caption-text\">Testing a lot of wheels in the wind tunnel showed some interesting results as yaw and speed changed <\/span><span class=\"credit\">(Image credit: Cyclingnews)<\/span><\/figcaption><\/figure>\n<p id=\"039a11e7-3331-404c-88b6-e95c9d236c00\">As a little side note, very rarely do brands test at angles as extreme as 20\u00b0 yaw. This is because, even at a rider speed of 30km\/h, for the yaw angle to be 20\u00b0, a 20km\/h wind has to be coming at you at an angle of 51\u00b0.<\/p>\n<p>If that wind is just 10kph, the required angle actually becomes unachievable since it is more than 90\u00b0, so a cross-tailwind. And given most aero-focussed products are developed for racers, they are often designed to be ridden at much higher speeds where the likelihood of experiencing 20\u00b0 or more is vanishingly small.<\/p>\n<p>In reality, yaw angles such as 20\u00b0 or more are unlikely to be experienced by a rider, so it is not really worth testing at those levels.<\/p>\n<p>It is sometimes used to create headline-grabbing marketing claims, but that&#8217;s a complaint for another day!<\/p>\n<\/div>\n<p>[analyse_source url=&#8221;https:\/\/www.cyclingnews.com\/bikes\/road\/how-can-a-bike-be-faster-in-a-crosswind-explaining-the-sail-effect-in-aerodynamics\/&#8221;]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[analyse_image type=&#8221;featured&#8221; src=&#8221;https:\/\/cdn.mos.cms.futurecdn.net\/6pS5duKXYjzhFBEkw9zVDE-2560-80.jpghttps:\/\/cdn.mos.cms.futurecdn.net\/6pS5duKXYjzhFBEkw9zVDE-2560-80.jpg&#8221;] Bikes Road Bikes How can a bike be faster in a crosswind?
