The Bunker is one of a handful of droppers with a cartridge designed to purge air when dropped. Bike Yoke\u2019s Revive and Wolf Tooth\u2019s Resolve also feature cartridges that allow the rider to purge air from the oil chamber. What makes this dropper unique is its dual-chamber design, which features two air chambers separated by an oil bath. When the rider actuates the seatpost, a port opens, pushing a piston through the oil bath and allowing the slider to drop into the seatpost body. As with Wolf Tooth\u2019s Resolve, this system is self-bleeding and purges air each time the seatpost is compressed.<\/p>\n<div style=\"text-align: center\">\n<div class=\"lazyloadPreSize lbContainer lbContainer--inline   \" data-xf-init=\"lightbox\" data-lb-single-image=\"1\" data-lb-container-zoom=\"1\" data-lb-trigger=\".js-lbImage-attachment2087269\" data-lb-id=\"attachment2087269\" style=\"padding-bottom: 58.438959306204%;padding-bottom: min(58.438959306204%, 876px);width:100%;width: min(100%, 1499px)\">\n<div class=\"lbContainer-zoomer js-lbImage-attachment2087269\" data-src=\"https:\/\/www.mtbr.com\/attachments\/bunker-main-points-png.2087269\/\" aria-label=\"Zoom\"><\/div>\n<p>                <img data-src=\"https:\/\/www.mtbr.com\/attachments\/bunker-main-points-png.2087269\/?auto=webp&amp;fit=bounds&amp;format=pjgp&amp;height=1920&amp;optimize=high&amp;width=1920\" class=\"bbImage lazyload\" data-zoom-target=\"1\" data-url alt=\"Font Circuit component Parallel Technology Electronic component\" title><\/p>\n<div class=\"lazyloading-shimmer shimmer animate \" style=\"width: min(100%, 1499px)\"><\/div>\n<\/p><\/div>\n<\/div>\n<p>The upper air chamber is set to approximately 3.6 times the rider\u2019s weight in kilograms and supports the rider at full extension.

As a fan of swift seatposts with an audible \u201cthunk\u201d at top out, I increased the air pressure on my test post to 320psi. Turnon notes that the recommended air pressure range for all users should be between 200 and 420psi. The lower chamber is set at the ambient air pressure, and both chambers work together to return the post to full extension when the lever is depressed again.<\/p>\n<p>The Bunker\u2019s air-oil-air sandwich design proved rock solid during testing, with no sagging and zero need for maintenance during more than a year of testing. Turnon relies on IGUS bushings to limit play, and a high-quality wiper seal prevents the ingress of dirt and debris. The service interval for this dropper is also impressive. Turnon claims the Bunker should be serviced every three years or 400 hours\u2014double that of many dropper seatposts.<\/p>\n<div style=\"text-align: center\">\n<div class=\"bbMediaWrapper\">\n<div class=\"bbMediaWrapper-inner\"><\/div>\n<\/div>\n<\/div>\n<p>Turnon\u2019s dropper lever features a short throw design, pulling the cable just six millimeters.

The lever is also highly adjustable, allowing the rider to angle it around the main axis and move it 4.5mm closer or further away from the handlebar. Riders aren\u2019t locked it using the brand\u2019s remote, though some aftermarket levers may require more lever force.

Its performance has been flawless\u2014the Bunker seatpost is smoother and more affordable than many of its competitors. I would rate its action as smoother than both OneUp and PNW, and on par with the performance of Wolf Tooth and BikeYoke. Despite this, there are a couple of nits left to pick.<\/p>\n<p>First, the drop and diameters are rather limited. The 190mm version I tested is the longest option currently available. Many long-legged riders would appreciate having 210mm or 240mm versions to choose from. Second, due to its dual air chamber cartridge, the Bunker&#8217;s insertion length is longer than several of our favorite droppers.<\/p>\n<div style=\"text-align: center\">\n<div class=\"lazyloadPreSize lbContainer lbContainer--inline   \" data-xf-init=\"lightbox\" data-lb-single-image=\"1\" data-lb-container-zoom=\"1\" data-lb-trigger=\".js-lbImage-attachment2087272\" data-lb-id=\"attachment2087272\" style=\"padding-bottom: 56.171875%;padding-bottom: min(56.171875%, 719px);width:100%;width: min(100%, 1280px)\">\n<div class=\"lbContainer-zoomer js-lbImage-attachment2087272\" data-src=\"https:\/\/www.mtbr.com\/attachments\/img_5162-large-jpeg.2087272\/\" aria-label=\"Zoom\"><\/div>\n<p>                <img data-src=\"https:\/\/www.mtbr.com\/attachments\/img_5162-large-jpeg.2087272\/?auto=webp&amp;fit=bounds&amp;format=pjgp&amp;height=1920&amp;optimize=high&amp;width=1920\" class=\"bbImage lazyload\" data-zoom-target=\"1\" data-url alt=\"Writing implement Office supplies Pen Writing instrument accessory Tints and shades\" title><\/p>\n<div class=\"lazyloading-shimmer shimmer animate \" style=\"width: min(100%, 1280px)\"><\/div>\n<\/p><\/div>\n<\/div>\n<p>\nIs this a deal breaker? That will depend on you and your bike. If you\u2019re on the cusp of being able to run a longer-stroke dropper on your frame, a seatpost with a lower stack height and shorter insertion length might be a better option for riders looking to maximize their drop. The Bunker is an excellent choice if you have plenty of room in your seat tube.<\/p>\n<div class=\"bbTable\">\n<table style=\"width: 100%\">\n<tr>\n<td><b><span>Seatpost Make &amp; Model<\/span><\/b><\/td>\n<td><b><span>MSRP<\/span><\/b><\/td>\n<td><b><span>Weight w\/o Cable and Lever<\/span><\/b><\/td>\n<td><b><span>Max Insertion Length + Cable Actuator<\/span><\/b><\/td>\n<td><b><span>Stack Height (Dropper Seatpost Collar Height)<\/span><\/b><\/td>\n<\/tr>\n<tr>\n<td><b>Turnon Bunker 190mm<\/b><\/td>\n<td>$289.00<\/td>\n<td>550g<\/td>\n<td>312.4mm<\/td>\n<td>36.3mm<\/td>\n<\/tr>\n<tr>\n<td><b>Wolf Tooth Resolve, 200mm<\/b><\/td>\n<td>$379.95<\/td>\n<td>563g<\/td>\n<td>291.2mm<\/td>\n<td>32mm<\/td>\n<\/tr>\n<tr>\n<td><b>BikeYoke Revive 2.0, 213mm<\/b><\/td>\n<td>$380.00<\/td>\n<td>645g<\/td>\n<td>327mm<\/td>\n<td>42mm<\/td>\n<\/tr>\n<tr>\n<td><b>OneUp V3, 210mm<\/b><\/td>\n<td>$269.99<\/td>\n<td>538g<\/td>\n<td>305mm<\/td>\n<td>30mm<\/td>\n<\/tr>\n<tr>\n<td><b>PNW Loam, 200mm<\/b><\/td>\n<td>$209.00<\/td>\n<td>598g<\/td>\n<td>290mm<\/td>\n<td>50mm<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<p>\nIn the United States, Turnon is distributed through BTI, so virtually any bike shop in the country should be able to order one.

The Bunker is one of a handful of droppers with a cartridge designed to purge air when dropped. Bike Yoke\u2019s Revive and Wolf Tooth\u2019s Resolve also feature cartridges that allow the rider to purge air from the oil chamber. What makes this dropper unique is its dual-chamber design, which features two air chambers separated by an oil bath. When the rider actuates the seatpost, a port opens, pushing a piston through the oil bath and allowing the slider to drop into the seatpost body. As with Wolf Tooth\u2019s Resolve, this system is self-bleeding and purges air each time the seatpost is compressed.<\/p>\n<div style=\"text-align: center\">\n<div class=\"lazyloadPreSize lbContainer lbContainer--inline   \" data-xf-init=\"lightbox\" data-lb-single-image=\"1\" data-lb-container-zoom=\"1\" data-lb-trigger=\".js-lbImage-attachment2087269\" data-lb-id=\"attachment2087269\" style=\"padding-bottom: 58.438959306204%;padding-bottom: min(58.438959306204%, 876px);width:100%;width: min(100%, 1499px)\">\n<div class=\"lbContainer-zoomer js-lbImage-attachment2087269\" data-src=\"https:\/\/www.mtbr.com\/attachments\/bunker-main-points-png.2087269\/\" aria-label=\"Zoom\"><\/div>\n<p>                <img data-src=\"https:\/\/www.mtbr.com\/attachments\/bunker-main-points-png.2087269\/?auto=webp&amp;fit=bounds&amp;format=pjgp&amp;height=1920&amp;optimize=high&amp;width=1920\" class=\"bbImage lazyload\" data-zoom-target=\"1\" data-url alt=\"Font Circuit component Parallel Technology Electronic component\" title><\/p>\n<div class=\"lazyloading-shimmer shimmer animate \" style=\"width: min(100%, 1499px)\"><\/div>\n<\/p><\/div>\n<\/div>\n<p>The upper air chamber is set to approximately 3.6 times the rider\u2019s weight in kilograms and supports the rider at full extension. According to the company\u2019s formula, my air pressure should be 70kg x 3.6 = 252psi. As a fan of swift seatposts with an audible \u201cthunk\u201d at top out, I increased the air pressure on my test post to 320psi. Turnon notes that the recommended air pressure range for all users should be between 200 and 420psi. The lower chamber is set at the ambient air pressure, and both chambers work together to return the post to full extension when the lever is depressed again.<\/p>\n<p>The Bunker\u2019s air-oil-air sandwich design proved rock solid during testing, with no sagging and zero need for maintenance during more than a year of testing. Turnon relies on IGUS bushings to limit play, and a high-quality wiper seal prevents the ingress of dirt and debris. The service interval for this dropper is also impressive. Turnon claims the Bunker should be serviced every three years or 400 hours\u2014double that of many dropper seatposts.<\/p>\n<div style=\"text-align: center\">\n<div class=\"bbMediaWrapper\">\n<div class=\"bbMediaWrapper-inner\"><\/div>\n<\/div>\n<\/div>\n<p>Turnon\u2019s dropper lever features a short throw design, pulling the cable just six millimeters. It has a very light action and is quick to engage with a light touch. The lever is also highly adjustable, allowing the rider to angle it around the main axis and move it 4.5mm closer or further away from the handlebar. Riders aren\u2019t locked it using the brand\u2019s remote, though some aftermarket levers may require more lever force.

The Bunker is one of a handful of droppers with a cartridge designed to purge air when dropped. Bike Yoke\u2019s Revive and Wolf Tooth\u2019s Resolve also feature cartridges that allow the rider to purge air from the oil chamber. What makes this dropper unique is its dual-chamber design, which features two air chambers separated by an oil bath. When the rider actuates the seatpost, a port opens, pushing a piston through the oil bath and allowing the slider to drop into the seatpost body. As with Wolf Tooth\u2019s Resolve, this system is self-bleeding and purges air each time the seatpost is compressed.<\/p>\n<div style=\"text-align: center\">\n<div class=\"lazyloadPreSize lbContainer lbContainer--inline   \" data-xf-init=\"lightbox\" data-lb-single-image=\"1\" data-lb-container-zoom=\"1\" data-lb-trigger=\".js-lbImage-attachment2087269\" data-lb-id=\"attachment2087269\" style=\"padding-bottom: 58.438959306204%;padding-bottom: min(58.438959306204%, 876px);width:100%;width: min(100%, 1499px)\">\n<div class=\"lbContainer-zoomer js-lbImage-attachment2087269\" data-src=\"https:\/\/www.mtbr.com\/attachments\/bunker-main-points-png.2087269\/\" aria-label=\"Zoom\"><\/div>\n<p>                <img data-src=\"https:\/\/www.mtbr.com\/attachments\/bunker-main-points-png.2087269\/?auto=webp&amp;fit=bounds&amp;format=pjgp&amp;height=1920&amp;optimize=high&amp;width=1920\" class=\"bbImage lazyload\" data-zoom-target=\"1\" data-url alt=\"Font Circuit component Parallel Technology Electronic component\" title><\/p>\n<div class=\"lazyloading-shimmer shimmer animate \" style=\"width: min(100%, 1499px)\"><\/div>\n<\/p><\/div>\n<\/div>\n<p>The upper air chamber is set to approximately 3.6 times the rider\u2019s weight in kilograms and supports the rider at full extension. According to the company\u2019s formula, my air pressure should be 70kg x 3.6 = 252psi. As a fan of swift seatposts with an audible \u201cthunk\u201d at top out, I increased the air pressure on my test post to 320psi. Turnon notes that the recommended air pressure range for all users should be between 200 and 420psi. The lower chamber is set at the ambient air pressure, and both chambers work together to return the post to full extension when the lever is depressed again.<\/p>\n<p>The Bunker\u2019s air-oil-air sandwich design proved rock solid during testing, with no sagging and zero need for maintenance during more than a year of testing. Turnon relies on IGUS bushings to limit play, and a high-quality wiper seal prevents the ingress of dirt and debris. The service interval for this dropper is also impressive. Turnon claims the Bunker should be serviced every three years or 400 hours\u2014double that of many dropper seatposts.<\/p>\n<div style=\"text-align: center\">\n<div class=\"bbMediaWrapper\">\n<div class=\"bbMediaWrapper-inner\"><\/div>\n<\/div>\n<\/div>\n<p>Turnon\u2019s dropper lever features a short throw design, pulling the cable just six millimeters. It has a very light action and is quick to engage with a light touch. The lever is also highly adjustable, allowing the rider to angle it around the main axis and move it 4.5mm closer or further away from the handlebar. Riders aren\u2019t locked it using the brand\u2019s remote, though some aftermarket levers may require more lever force. I also tested this post with Wolf Tooth\u2019s ReMote Pro lever and didn\u2019t notice much of a difference in lever feel.<\/p>\n<div style=\"text-align: center\">\n<div class=\"lazyloadPreSize lbContainer lbContainer--inline   \" data-xf-init=\"lightbox\" data-lb-single-image=\"1\" data-lb-container-zoom=\"1\" data-lb-trigger=\".js-lbImage-attachment2087273\" data-lb-id=\"attachment2087273\" style=\"padding-bottom: 75%;padding-bottom: min(75%, 1080px);width:100%;width: min(100%, 1440px)\">\n<div class=\"lbContainer-zoomer js-lbImage-attachment2087273\" data-src=\"https:\/\/www.mtbr.com\/attachments\/1711038264847-png.2087273\/\" aria-label=\"Zoom\"><\/div>\n<p>                <img data-src=\"https:\/\/www.mtbr.com\/attachments\/1711038264847-png.2087273\/?auto=webp&amp;fit=bounds&amp;format=pjgp&amp;height=1920&amp;optimize=high&amp;width=1920\" class=\"bbImage lazyload\" data-zoom-target=\"1\" data-url alt=\"Camera accessory Font Output device Auto part Brand\" title><\/p>\n<div class=\"lazyloading-shimmer shimmer animate \" style=\"width: min(100%, 1440px)\"><\/div>\n<\/p><\/div>\n<\/div>\n<p>Speaking of more force, before sending this seatpost for review, a Turnon representative emailed me a list of the Bunker post&#8217;s highlights and several cons of its design relative to the competition. I\u2019m not accustomed to this level of candor from cycling companies, but I respected their honesty. One of the cons listed is its higher breakaway force\u2014a byproduct of a well-sealed system. It\u2019s noticeable when using one\u2019s hand to push the saddle down in a parking lot test, but a non-issue when riding.<\/p>\n<p>\n<span style=\"font-size: 26px\">Is the Turnon Bunker dropper post a good buy?<\/span><\/p>\n<div style=\"text-align: center\"><span style=\"font-size: 26px\"><\/p>\n<div class=\"lazyloadPreSize lbContainer lbContainer--inline   \" data-xf-init=\"lightbox\" data-lb-single-image=\"1\" data-lb-container-zoom=\"1\" data-lb-trigger=\".js-lbImage-attachment2087271\" data-lb-id=\"attachment2087271\" style=\"padding-bottom: 56.171875%;padding-bottom: min(56.171875%, 719px);width:100%;width: min(100%, 1280px)\">\n<div class=\"lbContainer-zoomer js-lbImage-attachment2087271\" data-src=\"https:\/\/www.mtbr.com\/attachments\/img_5160-large-jpeg.2087271\/\" aria-label=\"Zoom\"><\/div>\n<p>                <img data-src=\"https:\/\/www.mtbr.com\/attachments\/img_5160-large-jpeg.2087271\/?auto=webp&amp;fit=bounds&amp;format=pjgp&amp;height=1920&amp;optimize=high&amp;width=1920\" class=\"bbImage lazyload\" data-zoom-target=\"1\" data-url alt=\"Office supplies Writing implement Tints and shades Electric blue Wood\" title><\/p>\n<div class=\"lazyloading-shimmer shimmer animate \" style=\"width: min(100%, 1280px)\"><\/div>\n<\/p><\/div>\n<p><\/span>\u200b<\/div>\n<p>With a price range of $252 &#8211; $289, depending on the amount of travel, it\u2019s a great buy compared to several of the top-droppers I mentioned in the introduction. Its performance has been flawless\u2014the Bunker seatpost is smoother and more affordable than many of its competitors. I would rate its action as smoother than both OneUp and PNW, and on par with the performance of Wolf Tooth and BikeYoke. Despite this, there are a couple of nits left to pick.<\/p>\n<p>First, the drop and diameters are rather limited. The 190mm version I tested is the longest option currently available. Many long-legged riders would appreciate having 210mm or 240mm versions to choose from. Second, due to its dual air chamber cartridge, the Bunker&#8217;s insertion length is longer than several of our favorite droppers.<\/p>\n<div style=\"text-align: center\">\n<div class=\"lazyloadPreSize lbContainer lbContainer--inline   \" data-xf-init=\"lightbox\" data-lb-single-image=\"1\" data-lb-container-zoom=\"1\" data-lb-trigger=\".js-lbImage-attachment2087272\" data-lb-id=\"attachment2087272\" style=\"padding-bottom: 56.171875%;padding-bottom: min(56.171875%, 719px);width:100%;width: min(100%, 1280px)\">\n<div class=\"lbContainer-zoomer js-lbImage-attachment2087272\" data-src=\"https:\/\/www.mtbr.com\/attachments\/img_5162-large-jpeg.2087272\/\" aria-label=\"Zoom\"><\/div>\n<p>                <img data-src=\"https:\/\/www.mtbr.com\/attachments\/img_5162-large-jpeg.2087272\/?auto=webp&amp;fit=bounds&amp;format=pjgp&amp;height=1920&amp;optimize=high&amp;width=1920\" class=\"bbImage lazyload\" data-zoom-target=\"1\" data-url alt=\"Writing implement Office supplies Pen Writing instrument accessory Tints and shades\" title><\/p>\n<div class=\"lazyloading-shimmer shimmer animate \" style=\"width: min(100%, 1280px)\"><\/div>\n<\/p><\/div>\n<\/div>\n<p>\nIs this a deal breaker? That will depend on you and your bike. If you\u2019re on the cusp of being able to run a longer-stroke dropper on your frame, a seatpost with a lower stack height and shorter insertion length might be a better option for riders looking to maximize their drop. The Bunker is an excellent choice if you have plenty of room in your seat tube.<\/p>\n<div class=\"bbTable\">\n<table style=\"width: 100%\">\n<tr>\n<td><b><span>Seatpost Make &amp; Model<\/span><\/b><\/td>\n<td><b><span>MSRP<\/span><\/b><\/td>\n<td><b><span>Weight w\/o Cable and Lever<\/span><\/b><\/td>\n<td><b><span>Max Insertion Length + Cable Actuator<\/span><\/b><\/td>\n<td><b><span>Stack Height (Dropper Seatpost Collar Height)<\/span><\/b><\/td>\n<\/tr>\n<tr>\n<td><b>Turnon Bunker 190mm<\/b><\/td>\n<td>$289.00<\/td>\n<td>550g<\/td>\n<td>312.4mm<\/td>\n<td>36.3mm<\/td>\n<\/tr>\n<tr>\n<td><b>Wolf Tooth Resolve, 200mm<\/b><\/td>\n<td>$379.95<\/td>\n<td>563g<\/td>\n<td>291.2mm<\/td>\n<td>32mm<\/td>\n<\/tr>\n<tr>\n<td><b>BikeYoke Revive 2.0, 213mm<\/b><\/td>\n<td>$380.00<\/td>\n<td>645g<\/td>\n<td>327mm<\/td>\n<td>42mm<\/td>\n<\/tr>\n<tr>\n<td><b>OneUp V3, 210mm<\/b><\/td>\n<td>$269.99<\/td>\n<td>538g<\/td>\n<td>305mm<\/td>\n<td>30mm<\/td>\n<\/tr>\n<tr>\n<td><b>PNW Loam, 200mm<\/b><\/td>\n<td>$209.00<\/td>\n<td>598g<\/td>\n<td>290mm<\/td>\n<td>50mm<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<p>\nIn the United States, Turnon is distributed through BTI, so virtually any bike shop in the country should be able to order one.
