Why We Like The 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.

Great piece of equipment!

Very reliable and easy to install. Anything greater than the 180 would have been too long for me?probably should?ve done the 150mm. If you?re on the cusp, go 150

Longest and the shortest

Familiarity:

I can run a 170 slammed in the 2022 Fezzari La Sal Peak. Easy to grease and I'm just stoked that it's so much drop.

Great until it failed in < a year!

Familiarity:
I've put it through the wringer

The good: I really love this post, the style and build quality are excellent. For 11 months it worked flawlessly...sturdy, smooth actuation, reliable drop/return! The bad: On my last ride it just started dropping as soon as any weight was applied. Performed recommended maintenance and pressurized, but the post still drops as soon as any weight is applied. Appears to be an issue with the [unserviceable] sealed cartridge, possibly the brake mechanism because the post will also drop when the it's unpressurized, and the brake should prevent that behavior. *** I've just started the warranty process so I am not sure how the problem will be addressed. Assuming I get a replacement cartridge I'd be happy to keep the post in action...it rocked before this hiccup!

Happy I ordered this to replace my 125 dropper with a 180. I?m only 5? 7 but made sure prior to ordering this would fit my bike & I honestly couldn?t have a better fit for my set up. Worth the $

4 months old and already dead

Familiarity:
I've used it several times

I am by no means hard on my equipment. I?ve had a KS lev integra for 2 years without issues, a reverb for a year without issues, and a bike yoke revive for 2 years without issues. None of those I ever cleaned, wiped off, or did any sort of maintenance on them. When I got my new bike I wanted the biggest dropper I could fit which was the 180mm Oneup v2. I was also happy I?d be saving a few bucks as well. I heard they were prone to getting dirt inside the seal so I made sure to wipe off my stanchion before and after every ride to try and avoid that. However, barely 4 months (135 miles!) into owning it, dirt has made its way into the seal leaving a deep gouge in the stanchion. I don?t ride in the mud or any crazy conditions, my trails are all hard pack, and my bike is always stored inside. The fact that this happened is kind of ridiculous given my experiences with past droppers. Now, I?m trying to deal with the warranty process, which doesn?t make sense to me. I should be able to contact the company directly for warranty work, why should I contact backcountry (where it was purchased) when they don?t know your warranty guidelines? Save yourself the headache, spend a little more and get a reliable dropper.

So far so good

Familiarity:
I've used it several times

Pretty easy to install with internal routing. Only had a few rides with it so far but over all no issues at all. Very responsive when I recall it with good pressure. Fluid movement on the way down. No jerking or movement. Love it.

OK to Excellent, depending on the user.

Familiarity:
I've put it through the wringer

I've used several of these now, on various bikes. The packaging is great: nobody else comes close to the same travel for a given insertion or clamp-to-saddle rail distance. It's also pretty light, and fairly affordable. Installation is very easy. Travel-adjust is easy and can be done on-bike. The saddle clamp isn't the easiest to use, but the dropped design of the clamp is part of the key to the great drop numbers, so I find that easily forgivable. The post also has a little more fore/aft play than some others, again due to the closely-spaced bushings which give it that short insertion depth. For most people, this is a nearly-perfect post at a great bike. However, the 30.9 posts can bind when hilted, which is a major disappointment. Details on that below. One other fairly minor issue: it seems to be more sensitive to being clean and lubed than most posts. I have to clean and re-lube about twice as often as a post with top-notch seals and bushings, such as a Transfer. Fortunately, this is a very easy job that doesn't take any special tools. I do find that ONLY Slickoleum/Slick Honey/SRAM Butter (they are all the same stuff) works well. Regular general-purpose greases do not keep it from sticking. Details on that 30.9mm binding issue: depending on the frame, the 30.9 posts might bind when fully hilted when you torque the seatpost clamp. I don't think the applies to the larger-diameter posts, but I haven't tested enough to be sure. It absolutely happens on all the 30.9 posts that I've had in my hands. Sometimes I can find a happy medium where there's enough torque to hold the post, but not enough to bind. With other frame/clamp combinations, it will bind unless moved up high enough to put the upper bushing above the clamp area (about 15-20mm). This is possible with the included shims (unless you're already shimming it just to fit your frame), but either way it's a real bummer on a post that's essentially designed to be hilted. So, if you run a 31.6 or 34.9 post, don't mind lubing a little more frequently, and are looking for max travel for a given saddle height/frame combo... this is your dream post. If you run a 30.9 and want it hilted, probably look elsewhere (like a Bike Yoke or 2021+ Transfer). For everyone else, it's a solid choice, especially if weight and cost are concerns. FYI, other posts I've used a lot are the Command Post IRCC, Transfer, Koryak, Fall Line R, Tellis, and Reverb. Somehow I've never owned a KS...

Good dropper with one minor issue

Familiarity:
I've used it several times

Lighter than comparable droppers. Goes up and down. Solid. No reliability issues so far after a handful of rides. There is one design flaw. The front bolt to adjust the seat cannot be accessed with a multi-tool (I have three different mini ones and noand worked). Not enough clearance to the post. Have to use a traditional L shaped Allen key to reach it. It's a problem if you're out on the trail and need to adjust your seat but only brought a multi-tool.

210 Dropper

Familiarity:
I've put it through the wringer

I think that this one is the best I've ever used considering I've only used 2 other ones! It's got loads of travel and the insertion dept is nuts. I only measured about a million times to make sure it would fit turns out it fit more than enough! overall a great almost work of art the way the thing is built and easy to set up! one thing I do have to say is that you have to put 300 psi in the post in order for it to go up somewhat faster than how it comes. when you remove the shock pump tons of air does come out but that might just be an id10T error!

Works well, but noisy

Familiarity:
I've used it several times

I will start with the statement that for the money this is a great dropper, the short insertion is a definitely a huge benefit, which was the reason I decided to give it a try. I was able to go from 150 to 180, so I really wanted to make it work, but the deal breaker for me was the noise coming from the post. Based on the other reviews, it might be isolated case, but after messing with it for 4+ hours, and ruining few rides for me, I was over it, so I decided to pay a bit extra to the other guys. I did try few tricks few times, in order to solve for it, but not luck: opened and re-greased the post (slick honey grease), carbon paste in the tube, everything torqued to specs, sit clamp/rails lubed and even taped to be sure, cables/ferrules, etc. Seams quiet on the street by the house, but the moment I put pressure on it while pedaling on the trail it will start randomly seeking and clunking. The only thing I didn't do, was disassemble down to the cartridge, which I think is the issue, cause by possible rubbing on the upper tube. The moment I put my old dropper back, the noise was gone. Pros: Short Insertion (bigger drop), low cost, easy self service, cheap replacement parts, 2 year warranty Cons: Not as smooth as higher end brands, feels sticky at times, if you do short drop vs fully down (some slick honey helps, but still not quite there), last inch or so, to fully down required bit extra push at times, actuation requires extra effort (mine was 2.1), noise (could be isolated case), feels somewhat flimsy and doesn't inspire confidence for longevity (could be just me). Kudos to Competitive for working with me! Outstanding service as always!
