Get the most from every drop.

OneUp Components realizes that it's difficult to get the most drop from a traditional dropper post, due to wasted space inherent to popular droppers on the market, as well as things like interrupted seat tubes found on many frame designs. That's why OneUp Components created their Dropper Post to offer the absolute shortest stack height of any dropper on the market, period. OneUp's shorter dropper allows you to size up to their 150-millimeter option if you're currently using a 125-millimeter dropper or a lengthy 170-millimeter option if you're currently running a 150-millimeter dropper on your bike. This way, you can get in a lower, more aggressive position while descending without any undropped post sticking above your seat tube, preventing you from going lower off the rear end of your bike.

Not only is it the absolute shortest dropper post on the market, but OneUp offers a unique, travel-adjust shim that's 50 millimeters in length and trims down to your personalized needs, so you don't have to size down in dropper length if you're between sizes. This means you can achieve that 143.5 millimeters of drop with the 150-millimeter option or achieve 158 millimeters of drop with the 170-millimeter option by OneUp, making it a truly personalized dropper, seeing your physiology doesn't usually conform to rounded numbers.

For the dropper's operation, the OneUp Dropper Post uses a reliable cable-actuated that doesn't require bleeding to deliver smooth drops and speedy returns—though do note that the lever isn't included. Since the cable clamps at the lever, trimming it down for cable routing is a breeze. And since it's not a hydraulic dropper like some of the competition, it won't slow down or stick in those colder temperatures regularly experienced at higher elevations.

  • Shortest dropper on the market maximizes each drop length
  • Travel-adjustable shim lowers dropper's travel up to 50mm
  • Shim is trimmable for customizing the dropper's travel
  • Simple, cable-actuated remote doesn't require bleeding
  • OneUp Dropper Lever remote switch is sold separately

  • Familiarity: I've put it through the wringer

Super great for fine-tuning easy to use. Installation is simple and the thing is pretty durable. Fun for experimenting.

Great post, shims not included

  • Familiarity: I've used it several times

As the description mentions, this post stands out with its infinite adjustment. The shims that allow for the adjustment are sold separately. Snag them with item number OUC000V
