Description

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

Garbage

    I get an ibis ripley ls from competitive cyclist, it’s a great bike, but the one up dropper and lever not good at all.
    It’s get stuck, work only some times. I received an email from competitive asking me how is my ibis and assigning a person for help and answer any questions I have.
    So I told about the one up dropper, he says we can help to replace it but when I request the replacement he said they can’t, he said I have to deal with the manufacture.
    I try to fix the problem putting more air pressure and make sure don’t over tight the clamp and put grease on but any thing works. So I decides to throw it away and buy a better brand, and loose my money.
    So OneUp dropper is garbage and competitive cyclist not a good costumer service.

    Great dropper post at a great price!

    • Familiarity: I've used it several times

    I was lucky enough to pick this dropper post up during the black Friday sales so I got a ridiculously low price. That being said I would still buy it at the full price. It has more features than most any dropper post out there and it works great. OneUp really has their act together when it comes to filling in the small areas that other companies seem to leave out! They are very innovated to say the least...

    Great Dropper for a Great Price!

    • Familiarity: I've used it several times

    My Pivot Switchblade came with a 125mm Fox Transfer. I was pleased with it, but when I started looking to get a dropper that offered longer travel and comparing prices I had to consider the OneUp. I read several reviews and then a buddy picked up the OneUp. He kept saying it was great, but I kept saying how could it be? It's half the price, (Damn Near). Anyway I finally got one, and was thinking I have nothing to lose, Competitive treats me great, if I have a problem they'll stand behind me. Well I now have a few dozen rides on the OneUp and it works just it did on day one. Smooth operation, equal to my Fox Transfer, only difference is 55mm more travel.

    NOTE: This model requires a cable / lever and hardware.

    This was the longest dropper I could fit in my 2018 Switchblade and keep my saddle height correct. 30" mid saddle to center crank shaft.

    Great piece of equipment

    • Familiarity: I've used it several times

    Love the shims and the new 2.1 actuator is very easy to engage. Paired with the PNW Loam Lever, I am in dropper heaven. Being 6'2", I am running 180mm travel (shimmed to 160mm with the roller pins) and am about 1" from full insertion (lol). The post has a little side to side play, but every dropper has some eventually (the guides that stop a dropper post and keep it from rotating wear overtime, completely normal) The post is fast to rise and easy to drop with my body weight.

    Great post with one big flaw

    • Familiarity: I returned this product before using it

    Everything about it is great, but the actuation is too hard.

    Right out of the box, pressing the actuator on the bottom of the post proved too hard. It requires too much force. Even the buttery smooth actuator on my Reverb (B1) got tiring on long rides - this one requires twice the amount of force. The amount required to actuate this post even with a LA Wolftooth is too much - every single time. It is possible I got a defective post, but I ordered two in differences sizes and right out of the box both functioned the same. If you have super strong thumbs, this may not be an issue for you. I'm going to stick with the Reverb - no other post matches its smoothness. All cable actuated posts have friction, this one just too much of it.

    Bought one for my wife and she has no problem using it.

    Best Dropper for the Money

    Bought this to replace an E13 dropper on my YT Jeffsy. Had some issues with the E13 that a rebuild didn’t fix, so sent that out for warranty and replaced with OneUp. The ability to fit a 180mm dropper in a medium frame, with a 30” inseam is incredible. I didn’t even have to shim the travel down. This replaced a 150mm dropper, so now I have even more clearance with the dropper down. Installation was simple. This 31.6 post does come with the 2.1 actuator, so it is actuated by the cable pull and not the housing like the old version. Works well with my E13 remote. Post worked perfectly out of the box even with only 200psi in the air chamber, I inflated to 275 since the spec is 250-300. Operation is smooth and precise, no play at all. We’ll see how it lasts but seeing as this is the second generation of a post that was already well reviewed since it came out, I don’t think I’ll have any issues with it.

    FINALLY!

    If you're a short dude like me (5'7) you know how hard it is to find a dropper that will fit a FS MTB, especially Emtb's. The frames on my bikes can only accept 200mm of seat post before they hit a bend in the frame. If you want to be able to drop your seat almost down to the frame, yet have the enough rise to get into the proper ride height, this is the post you need. Most other posts that I have tried have 220mm+ housings, even on only 100mm rise. I now have 120mm of extension, and can still drop almost all the way down to the collar.
    It was a gamble however, OneUp doesn't give you "full insertion" specs so I took a chance on return costs to get this DP. I have the 31.6 x 120mm, distance below collar to bottom of actuator is 210mm, the actuator is only 10mm. The housing itself is 200mm. It is a little tricky to install, you have to keep constant tension of your cable or else the cable will slip out of the pocket in the actuator. There is an o-ring retention but it isn't adequate to keep the cable in the actuator pocket. It also came with what looks like needle bearings, have no idea what these are for, no instructions in box, and post came in compressed. Just thrilled to find a DP that fits my shortness. Two year warranty is great as well. The action is smooth and snappy.

    The bearings allow you to adjust your drop up 20mm.

    Those little brass pieces are shims to reduce the travel. OneUp has a video with install instructions.

    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 $$.
