The world’s shortest, long travel dropper post. Get the longest travel dropper that will fit you and your bike.


More drop = More fun. The further out of the way you can get your saddle on downhills the more confidence you’ll have and the harder you can ride. The shortest stack height of any dropper, period. No other post gets your saddle lower. And with the shortest effective length of any equivalent travel post on the market, most riders can now upgrade their 125mm or 150mm post to a 170mm OneUp dropper.


Don’t get stuck between dropper sizes. The unique OneUp travel adjust shims allow you to custom tune your post by lowering the travel and extended length of your post by as much as 50mm in any increment you like. Want an oh so fashionable 128.99mm drop? You got it! Drop tuning can be done on-bike, tool free and without removing the saddle or touching a shock pump. Lowering the post travel also increases bushing overlap, which is great for heavier riders.

170mm Dropper Post - adjustable* down to 120mm

150mm Dropper Post - adjustable* down to 100mm


With a simple and reliable cable actuated remote you never have to bleed your dropper remote again. The cable setup is quick and easy. The cable clamps at the lever making shortening the housing length for clean routing a breeze. Unlike a hydraulically actuated dropper, there is no temperature sensitivity and If your remote gets damaged you can still lower or extend your post by removing it from your frame and pushing on the actuator by hand.

BETTER REMOTE (sold separately)

An alloy remote with oversized bearing and a super smooth action. The unique lever position allows you to keep a stronger grip on the bars while actuating your post. Don't think twice about dropping your post, even when charging into technical sections. The OneUp lever mimics your R/H shifter’s inboard upshift paddle position instead of the usual downshift paddle position of most remotes. This position requires considerably less thumb movement to reach the lever.
