This year\u2019s Unbound Gravel was upended by the announcement from Scott on Tuesday that two of its athletes, including last year\u2019s 200-mile winner Cam Jones, will ride the race on a prototype 32-inch gravel bike. The company has not disclosed any details about the frame specifics, but we were able to speak with Cam Jones about the bike and why he made the switch to the prototype this year.<\/p>\n

While the 32-inch bike stole the headlines, there are plenty of more conventional pro bikes with unique setups, refined configurations, and bespoke solutions to problems like lubrication, a key aspect of a race as gritty as Unbound.<\/p>\n

We have been doing scores of bike checks from around Emporia the week leading to the race, and here are a few of the bikes we included in the video and a few others that caught our eye.<\/p>\n

Cam Jones, Scott Gravel Prototype<\/h2>\n
\"Cam
The type of bike that never fails to start an internet fight, 32-inch gravel bike. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n
\"Cam
Small head tubes for big tires. This was made simpler with Cam Jones and Robin Gemperle riding the same 56cm size. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n

The key juncture of these large wheel bike are finding ways to fit the bottom bracket in while retaining a steep effective seat tube angle. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n

\"Cam
With the larger wheels, normally people must use smaller cranks. Jones has a 48t on at the moment, but he is considering going bigger since he feels the overall system is faster. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n

The Canadian is known as Lespy by most.<\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n
\"Lespy
Normally, Lespy would be a big tire rider, pushing all the way to 2.25 Aspen ST\u2019s at a race like Unbound. Yet, with the potential for mud, it is back to narrower rubber for many of the experienced pros. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n

All looks normal here, but when you start zooming in, you see something interesting.<\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n
\"Lespy
Same on the front. Everything looks conventional, except one small button <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n

\"Lespy
The secret is found in the Faction Bike Studio chain catcher. There, Lespy has hidden an internal lubrication system connected to the button on the handlebars. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n
\"Lespy
This will keep things smooth throughout the race, applying wax-based lube to a pre-waxed chain. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n

Karo Migon, Rose Backroad<\/h2>\n

Karolina Migon is once again riding the Rose Backroad gravel frame. Rose is illusive for the US audience since the bikes are not available in North America, but are growing in popularity in Europe. <\/span><\/figcaption><\/figure>\n

The bike is largely the same as last year, except that Migon has a new cockpit that looks quite impressive. <\/span> (Photo: Logan Jones-Wilkins\/Velo)<\/figcaption><\/figure>\n
