Dropper Post V2

When we were a kid, we thought being called "short stack" was an insult to our not-so-lofty stature. It turns out, our heads just weren't in the right game. OneUp Components takes short stack to the max with its Dropper Post - V2, measuring in with the shortest stack height available, and shortest total length of any available dropper currently on the market. Much like the first iteration, the V2 features cable-actuated, infinitely adjustable drop, and a stack height so low that you can easily size up your dropper and enjoy more clearance when its time to buzz the back wheel on steep, aggressive descents.

Not only is it the absolute shortest dropper post on the market, but OneUp offers a unique, travel-adjust shim system with two 10-millimeter shims that enable you to trims down your post to your personalized needs by up to 20-millimeters, so you don't have to size down in dropper length if you're between sizes. This means you can achieve that 140 millimeters of drop with the 150-millimeter option or achieve 160 millimeters of drop with the 180-millimeter option by OneUp, making it a truly personalized dropper, seeing your physiology doesn't usually conform to every number on the market.

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.

  • OneUp's dropper post keeps things short in stack, long in drop
  • Two 10-millimeter travel adjust dims lets you fine-tune drop
  • Shortest stack height and total length allows you to size up
  • Reliable sealed cartridge internals handle the rigors of the trail
  • Simple, cable-actuated remote doesn't require bleeding
  • OneUp Dropper Lever remote switch is sold separately

Unanswered Question

Do these have the 2.0 or 2.1 actuators? OneUp has indicated all droppers are being changed to the 2.1 moving forward, but what to clarify which actuator yours have. Thanks!

180mm of drop on a small frame!?

  • Familiarity: I've used it several times

Installed the 180 dropper on my size SMALL Juliana Maverick (for the dudes out there, that's a 2019 Santa Cruz Hightower) complete with extra low standover AND a split-seat-tube-style frame. I am beyond impressed.

I dare say this is LIFE CHANGING. ALMOST as life changing as installing my first dropper post ever. I am prone to breaking out into a Super-Nerdy Happy Dance(!) just thinking about the awesomeness of this dropper (AND the fact that I no longer need a quick release seat tube collar in combination with my dropper because I finally have enough drop in my dropper that I don't have to adjust my seatpost mid-ride! And let's NOT discuss how embarrassing that was....for the last 5 years... /frowny face).

Install was easy. And if you think you've hit a snag after attaching the cable to the lever, you probably just need more air in the dropper.

I paired mine with a Wolf Tooth "Light Action ReMote" for SRAM matchmaker.

You will also need to purchase cable and housing separately.

How far backordered is this item? How soon will it be back in stock?

Not sure which size you're after, but it looks like we have a ton in stock right now.

Best dropper option out there

  • Familiarity: I've used it several times

I just installed this dropper on my XC/trail/endurance race bike, which previously had a 125mm Fox Transfer, because at the time, it's the only one that would fit. This has the least overall insertion depth of any dropper on the market, and I also saved some weight by switching.

I oped to get the 150mm Oneup (thinking about getting a Revekate seat pack and need 6" of tire clearance), but could have probably gone with the 180mm and put in a shim or two, which would have allowed me to slam my seat post to the frame. That's the great thing about this dropper - for riders who are shorter, or who are in an awkward size/frame range, this allows them to get the most possible drop and avoid weird situations. I've met short people who actually have to lower their dropper ever so slightly when they raise their seat to climb. This would fix that.

This thing has been reliable, was super easy to install, and will be very easy to self-service (replace cartridge, lube, replace actuator cable,etc). Well done oneup! Only thing left is to design one for 34.9 seatpost diameter.

I've ridden the reverb (hated it), Fox Transfer (liked it), and Bikeyoke (loved it). This is just as good as the Bikeyoke so far, and much less $$.
