OneUP Components’ New Dropper Post

The World's shortest, long-travel dropper post

OneUp Components has been solving problems with clever designs since it launched as a company. And now it has turned its attention to the dropper post.

The new OneUp Dropper Post makes up for a lack of creativity in its name with an interesting design. First and foremost, the post is shorter than others on the market, while maintaining a long drop. That means if you currently have a 125-millimeter, or 150-millimeter dropper, you just might be able to upgrade to a 170-millimeter.

That’s pretty cool, because more drop is more better, particularly at the same overall extended height. But what’s really game-changing about the OneUp dropper isn’t that it’s short, it’s that the post’s travel is adjustable. And easily adjustable. The post comes in two options: 170 millimeters and 150 millimeters, but both can be adjusted for up to 50 millimeters fewer, in any increment. So if you buy a 170-millimeter post but want a 162-millimeter post, no problem. Why does this matter? Maybe you aren’t tall enough to run a full 170-millimeter post, but a 150-millimeter post leaves unused room between the end of the stanchion and the frame’s seat clamp. With OneUp’s post, you get exactly the right amount of drop for your height.

From top to bottom: post collar, bushing and shim.

OneUP achieves this through the use of a shim. It’s a relatively simple process: Without removing your saddle or the post from your bike, loosen the Dropper Post collar and upper bushing and slide the 50-millimeter shim underneath both. This reduces travel by 50 millimeters. With the post in its shortest-travel position, raise the entire post to a a comfortable pedaling height. The distance between seat clamp and post collar is the same amount that you’ll want to trim from the shim. Loosen the Dropper Post collar and bushing again, and now trim the shim by your previous measurement, then refasten. If all went well, your post collar should be pressed against your seat clamp, and when fully extended the saddle height should be a perfect fit.

The post is cable actuated using a carbon, paddle-shifter style remote positioned in a way that OneUP claims requires less thumb movement than other remotes on the market. Routing is internal only and the dropper is available in 30.9-millimeter or 31.6-millimeter post diameter options. And all of this can be yours for $250 ($200 for the post and $50 for the remote).
