OneUp Components has been on fire, first with the recent release of its EDC range of hide-away tools and now, with the debut of a sharp-looking cable-actuated dropper seatpost that solves a number of nagging issues that most component makers seem to have overlooked. I had a chance to preview the new post and, so far, it's been impressive. OneUp offers no fancy name for its dropper. They offer it in a 150-millimeter stroke with a maximum insertion of 223 millimeters and a 170-millimeter stroke with a maximum insertion of 243 millimeters. Weights range from 565 to 509 grams, and the internals are simple. The post uses a replaceable cartridge and OneUp will be stocking parts. Reportedly, the post is user-serviceable by enthusiast-level garage mechanics, and to sweeten the deal, the post has a two-year warranty. Its MSRP is set at $200 a la carte, and if you want a remote lever (configured with a solo clamp, or to fit Shimano or SRAM integrated levers), it will cost you an additional fifty bucks.
The big news, however, is that using a simple three-prong plastic spacer, anyone with sharp scissors and opposable thumbs can reduce the stroke of OneUp's post up to 50 millimeters. Why is this a good thing? Well, there aren't many frames out there with straight or unblocked seat tubes, and people come in a wide variety of leg lengths. Mix those very real variables together and you get a whole bunch of riders who are hobbled by off-the-shelf posts with less than optimal strokes. OneUp allows those riders to choose a longer-stroke post than they could normally ride, and then shorten its travel just enough to eke out the maximum possible drop. It's plenty easy to advertise simple DIY solutions, but they don't always work out once you have the product in hand. I have such a bike (my Ibis Mojo 3 restricts me to a 125mm dropper), so I took up the challenge and installed OneUp's 170-millimeter post. The job went smoothly. Figuring out my maximum drop turned out to be simple: Push the post as far in the seat tube as possible, then use the remote lever to establish my maximum saddle height and mark it with tape. Fully extend the post, measure the space below the tape and that's how long the three-fingered plastic spacer has to be cut. The spacer slides into key ways inside the post. No tools are required - you simply unscrew the seal-head by hand, slide the plastic bushing out of the way, and slip the travel spacer into the three grooves. I was riding in fifteen minutes with a 155.5-millimeter-stroke OneUp dropper post.
I prefer to ride 150-millimeter droppers, so that's a win. In action, the post has a swift but measured extension rate that can be easily modulated for mid-stroke stops. The carbon-reinforced plastic remote has just-right ergonomics and tucks nicely beneath the left brake lever. So far, the post has no play in any direction. I think OneUp has a strong candidate on their hands and you can expect a full review later this summer. In the meantime, OneUp's Official press release is included below. - RC
PRESS RELEASE: OneUp ComponentsOneUp Dropper SeatpostAffordable, more drop, no bleeding, and a rad carbon remote. More drop equals more fun. The farther out of the way you can get your saddle on downhills, the more confidence you’ll have and the harder you can ride. Our OneUp dropper post has shortest stack height of any dropper, period. No other post on the market gets your saddle lower. And with the shortest effective length of any equivalent travel post out there, most riders can now upgrade their 125mm or 150mm post to a 170mm OneUp dropper.
TUNEABLE 170mm tuneable down to 120mm | 150mm tuneable down to 100mmDon’t get stuck between dropper sizes. The unique OneUp travel adjust shims allow you to custom tune your post by lowering the travel and extended length of your post by as much as 50mm in any increment you like.
The Travel Adjust Shim (patent pending) allows you to fine tune post travel to your ideal length.
Want an oh so fashionable 128.99mm drop? You got it! Drop tuning can be done on-bike, tool free and without removing the saddle or touching a shock pump. Lowering the post travel also increases bushing overlap, which is great for heavier riders.
The Shim fits into the keyways and sits under the top bushing.
No bleeding, Simple Setup With a simple and reliable cable-actuated remote, you'll never have to bleed your dropper remote again. The remote setup is quick and easy. The cable clamps at the lever, making shortening the housing length for clean routing a breeze. Unlike a hydraulically actuated dropper, there is no temperature sensitivity and If your remote gets damaged you can still lower or extend your post by removing it from your frame and pushing on the actuator by hand.
Unique Carbon RemoteA carbon remote with an oversized bearing and a super smooth actionThe unique lever position allows you to keep a stronger grip on the bars while actuating your post. Don't think twice about dropping your post, even when charging into technical sections. The OneUp lever mimics your shifter’s inboard upshift paddle position instead of the usual downshift paddle position of most remotes. This position requires considerably less thumb movement to reach the lever.
Three lever options: Discreet clamp, SRAM Matchmaker and Shimano I-Spec.
OneUp Lever (not pressed). Your first thumb knuckle provides a lot of grip strength when riding
Usual Lever (not pressed) No thumb contact on the grip = No grip. Next time your ride, try covering your R/H downshift lever for a descent

MENTIONS:
@OneUpComponents
Just because it comes OEM?
It is one of the worst droppers out there, I have ridden many on demos and rentals, none of them worked properly. Even the new one.
Then again, the Pike and Lyric are "benchmarks" as well, so the "guide"....
Good job OneUp, this is putting them on the next level!
Next: a crankset. Please.
Things are changing drastically now though so we'll see the effects of that in the next couple of years.
As for internal cable routing, I see no advantages.
@goldfly: To me, the bike feels alive when I'm standing and the saddle is low. Raising the saddle and sitting down definitely takes that away for me. I can understand that for longer rides the seated position may preserve some energy so being able to switch on the fly allows those on longer rides to preserve energy where they need and still drop the saddle to make the bike come alive. But my rides are so short that there is no point preserving energy. Last week at the pumptrack I saw a guy on a 29er with a raised saddle attempt to do his laps. I was on my BMX. I explained him to drop his saddle. It would go only so far as the seattube was blocked by the bottle cage bolts. It may have been 128.99mm drop already though. Helped slightly, but not enough. Eventually I removed the entire seatpost. That must have given at least 170mm more room. I tried to ride that bike, felt scary as! Of course a mountainbike trail is no pumptrack, but I really wouldn't like to have my saddle that high as being the lowest position. Now with external cabling, you can use a qr clamp to drop the entire dropper post when the trail calls for that. So that you can switch between slammed and 170mm higher than that (as a "trail" setting). But with internal cabling, you don't want to do that. It may kink the cable inside. So you lose the flexiblity. I'm about 6ft tall, my seattube is 400mm long. If I want to go all the way up to XC height (when I have to ride a longer section over the road to get there) and I use a 400mm seatpost and raise it until I've got the minimum required 100mm inside the frame. And I can still slam it when I need to. I have 300mm of adjustment, just not on the fly. No dropper has that amount of travel. Paired with a qr lever you can have the flexibility, but then you need external routing.
Life is so much better with the dropper. Right up there with modern disk brakes and longer travel modern suspension.
@dangerwank : Surprised to see you didn't think you would have needed it ten years ago. It is simple to check. Ride with the saddle high. Then ride with the saddle low. See what you like. If you enjoy both from time to time, get a dropper to have this adjustment on the fly. If you only like the saddle high, learn to ride with a low saddle too and then get a dropper. If you only like saddle low then well, what to do? Learn to ride with a high saddle? I tried it for a while, didn't like it. Not on the climbs, not on the level stuff. For me it is only good to relax on the not so interesting bits. For me to have a dropper make sense there are three requirements. 1) I need to have such sections in my ride. 2) I feel the need to relax on those sections (so they need to be at least of decent length). 3) Interesting and "boring" (saddle up) sections have to alternate frequently enough for on the fly adjustment to make sense. I can imagine those conditions, but as it is they don't apply to me. My current hardtail frame wouldn't even take a dropper post (the DMR takes a 26.8mm seatpost). My next one is on the way and does have a compatible seattube, should I feel the need for one at some point. And just to prepare you, yes I have no intentions to hold onto that one for less than ten years. So here are the answers to the questions you have ten years from now. No I don't have Facebook, Snapchat, Whatsapp, Twitter, Whateverishipapp. Not now, not ten years from now. If you want to talk, drop by for a cup of tea.
@VwHarman : No need to worry about @dangerwank. Let him be upvoted to where there is no good music anymore.
I'm a OneUp fanboy too, but apparently we have differences. I don't understand why you would want to charge a fork by park jumping your fully, or why you would want to store a multi-tool in a dropper. That's like trying to stuff a flat tire patch kit in your rear shock. Do you have any common sense?
How about if OneUp makes a really nice cassette or some sweet brakes? I absolutely love their Switch chainrings.
Pleeeease.
Is it possible, sure, you can do it if youre well organized and have step by step instructions in front of you, but it is in no way "easy"
you mean a piece of ready rod nut and washer ?
not tring to argue but it was by far the easiest post i have rebuild to date yet
I still wouldn't consider it "easy" not stupidly difficult, but not easy. way too many small parts Especially when servicing the brake assembly (which is not part of the regular rebuild, but I had to do it on mine) Even the guys at 9.8 warned me that it wasn't "easy" Hell I'm pretty sure the pinkbike review of the post even noted how much of a pain in the ass it is to set up initially.
So, no, not "easy"
I take my hat off Oneup!
Cant really decide between these two...maybe Oneup for my hardtail and the Manic for my FS.
Get them ready for European Dealers as soon as possible please
Looks like a winner if it turns out to be reliable. Price and features are bang on.
That said, does having it that far back allow enough thumb extension to activate the post or is the throw required to activate it really short (e.g. like upshifting)?
@OneUpComponents...what is the FULL insert length including the mechanism on the bottom? That is how KS measures theirs: www.kssuspension.com/wp-content/uploads/2017/11/2018-LEV-integra.pdf. Their 150mm dropper is 240mm in total length including the attachment mechanism.
Looks like yours @150mm is 223mm, but what about the mechanism on the end? That's what matters

Now they're all out of stock...are there gonna be a lot of people with seat posts that are too long until the shims come into stock??
Might have been an idea to release all the items at once...pity, because I really wanted to try one of these.
Edit: Upon actually reading the post carefully, the answer to my question is the right one. Good shit, Oneup.
If Youre not worried about money go Revive .. otherwise the Oneup
The Revive has been out for quite some time and got only positive reviews... you cant really go wrong with either imho
My gf has got a small reign and the 125mm reverb is slighty too high for her as she cannot pull it all the way down.
if that fixes it then you got yourself a sale..
Checkout our guide here.

Love the dig at SRAM! Right in the press realease. 1 28.99. Such a joke. “It’s 28.99% better” has become a standard piece of sarcasm amongst my friends.
The seat post was free shipping (good), but it took 10 days to get here. If the shims take a week as well I won't get to install the dropper until... about a month from now.
Please call it the OneDown Dropper
(My reverb actually works great but has SO much play)
I am likely to pick one up at the Sea Otter.
I laughed.
Why only i-spec II though?
Saddle in my Spec Command is so far back it's not even funny. And that's on a 74.5 degree seat tube. I'm physically not able to ride bikes with 76 degree seat tubes - the seat just won't slide far back enough!
I only know of Command and 9point8 posts which have setbacks - am I missing something?
plus why would you want to? the reverb remote sucks
"Hi,
This sounds frustrating.
I can tell you that no direct mount ring has more offset than 6mm, our or anyone's.
Sorry i don't have more answers.
(Person from Oneup)"
A+++ Very helpful.
I just wish they had more knowledge about chainlines to help customers troubleshoot OneUp chainrings.
Makes me wonder if I'd get the same helpful response if I had an issue with their seat dropper... "Sorry, we don't have any answers". Pretty disappointing product support.
