OneUp Components 170mm Dropper Post
- OneUp Image


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.
OneUp dropper
I installed the OneUp post in an Ibis Mojo 3, which increased my drop from 125mm to 155mm.

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.

Measure your saddle height vs post at full extension...

Cut the spacer to that length...

...And slip the spacer into the key way slots inside the post.

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.

PRESS RELEASE: OneUp Components


OneUp Dropper Seatpost
Affordable, 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 100mm

Don’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.

OneUp Components 170mm Dropper Post Travel Reducing Shim
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 Remote
A carbon remote with an oversized bearing and a super smooth action

The 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.

 I dont even get how the Reverb is a reference point or "benchmark" as marketing people like to say?
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"....

 FINALLY, someone designs a proper remote. How has no one figured this out before??????? So many designs make you break your grip on the bar to engage the dropper. The Reverb plunger is the worst offender (might as well take your hand off the bar even when it's mounted underneath). Bravo OneUp.

 I thought they now have a grip shift to operate the dropper. Not saying it is the best solution for everyone, but at least it doesn't require you to release the bar to operate the dropper so they have that covered. I have no experience with dropper posts yet as most of my rides are under two hours long, so no need to raise the saddle and sit down. But yeah, this one indeed looks nice. Internal cable routing puts me off though.
  • + 6
 @vinay: i'd personally rather take my thumb off than change wrist positioning. Also - internal cable routing might be a bit of a pain to set up, but would 100% rather have it than external for a dropper post.

 @vinay: The appeal of having a dropper has nothing at all to do with ride length. They make rides more fun whether it's 10 minutes long or 8 hours.

flag vinay (Apr 18, 2018 at 9:53) (Below Threshold)
 @connorjuliusjohnson: Yeah, I'd probably also prefer using the thumb than the wrist. That said, when I used a front mech I operated it with a grip shift (with trigger for the rear mech). But I think I operated it with thumb and index finger, not my whole wrist. Only when my fingers were injured or frozen or for some other reason not strong enough, I'd resort to the wrist motion. But yeah for something more binary like operating a dropper post, I'd prefer a paddle like this.

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.
  • + 1
 @vinay: looks cleaner and no cable sticking out on it to get snagged on anything, especially if its a non collar option that moves up and down with the saddle. But you don't ride with a dropper so shouldn't really matter for you!
  • + 6
 @vinay: I used to ride non-dropper posts and lower with the quick release as you do. Thought people were crazy adding so much weight to the bike. And dropper posts were very expensive then. Then I bought a bike that came with one. Only 125mm drop. Within 2 rides I was a convert. Where I ride, Squamish BC, most trails have up and down components. So, to save stopping several times on the trail, you had to choose either up or down. Up, things got very hard on sketchy descents. Down, you wore your legs out on some of the climbs. Get off and adjust the post each time and you lost your riding buddies who weren't stopping.
Life is so much better with the dropper. Right up there with modern disk brakes and longer travel modern suspension.

 @Circe: All respect to WT - They make great stuff. The OneUp paddle position is concave vs convex and further under the grip.

 @jaimegrant: First of all let me get out of the way: I don't question the use of dropper seatposts. Actually I believe that probably every mountainbiker benefits from riding with a low saddle at least for some demanding sections of the trail. So as a consequence, whoever feels the need to also ride with a high saddle for other sections would benefit from the possibility to adjust saddle height on the fly. Which is what a dropper seatpost allows you to do. I also benefit from a low saddle. There are just no sections where I'd benefit from a high saddle. Back when I rode 30 to 45 minutes to and from the trails (over the road) I used to raise the saddle up to XC height on the streets and lowered them when I hit the trails. So that's where a qr clamp comes handy, but hardly any use for a dropper. Personally I don't like to climb seated. I find it much easier to stomp on the pedals when standing up. On my current (ten year old) frame my kneepads still hit the handlebars on the steeper climbs so that limits my range of movement, but my next frame has much longer reach so this gives me even more room to move around so standing climbing will only become more enjoyable. But my climbs are short. I can imagine really long climbs would wear me out whilst standing. But then again sitting down kills the fun of the climbing. No hops, rollbacks, weight shifts even. If I'm too tired for standing climbs, it is time for a picknick Smile .

 @vinay: your needs and wants are spot on for the year if your bike. I didn't know I needed a dropper ten years ago either. All good. How's your myspace?
  • + 0
 @dangerwank: maybe his needs and wants are spot on for him, regardless of bike. The reality is that the parts of a bike that make it function are not dropper posts. Bikes can still be super fun without a dropper, it is about what you are trying to accomplish. You don’t need a dropper. You can want one, you can love to have one, but if not having one means you won’t ride your bike, you should maybe check your priorities before you worry about @vinay checking a MySpace page. Besides, I just sent him an ICQ message, and he says he is out having fun on his non dropper post bike...

 @vinay: I hear you about the short technical climbs. A lot of the time I have a 40+ minute climb to get to the descent. Standing and mashing that long would likely blow out one of my old knees.Wink
  • + 0
 @jaimegrant: Yeah, I get that and I definitely get that a dropper seatpost makes sense for you. For me it doesn't, at this point. I live in The Netherlands. Height differences are somewhere in the tens of meters. A few hours driving gets me across the border and gives me more but nowhere the lengths of what you have there. Fourty minutes sounds like a good while. Standing goes with a heavier gearing than seated. And quite simply to sustain a heavy gearing like that for that long can indeed be tough. Different riders, different conditions, good we have the choice to ride with the equipment we want Smile .

@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.

 @stella10: then I wonder... why not make a valve and additional air chamber inside every air sprung fork? Like internal charger pump? You turn the switch, pump the fork by jumping on it. Turn the switch after you are done and it inflates the main chamber. Same could be done for a shock, just make an additional piggy back! I mean why not? Another great idea - make a double ring NW chainrings! Frame with internal water bottle in the top tube for @mikelevy. Then a bettery into a normal water bottle and 250W motor into the seat tube so that nobody knows!

 @WAKIdesigns: Waki, you should totally start your own shop, mass produce your products in Taiwan by the thousands, and then get them reviewed on Pinkbike. I think you will get some feedback!

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?

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.

 Spacers are something like $10 each? You can get a bunch and have as many different drops as you want.
  • + 17
 @MisterChow: Shims will be sold 3 in a pack for $10
  • + 5
 That's a smart product. With lots of companies specing super short seat tubes on long travel bikes, saddle/tire interference is bound to happen, especially for those with shorter legs.
  • + 5
 I love the fact that the remote is very inward, when things get sketchy i find it sometimes scary to take my thumb of the grip. I use the Fox remote on the handlebar not below... yes i still ride 2x10
  • + 6
 With an offer like this, why would anyone choose any other dropper? Well done OneUp...shame a few months too late for me...
  • + 3
 I like the idea of the lever being further back, so I can keep a better grip on the bars when changing position.

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)?
  • + 5
 The throw is a little more than an upshift but there is more then enough room to activate the post. As well our lever mounts provide some rotational and lateral adjustment to tune to your preferred position.
  • + 3
 Looks rad!

@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 Smile
  • + 1
 @hockeydavey the actuator mech is 32mm long.
  • + 3
 Hang on a second, am I missing something here? From what I can see, the overall length of the 150mm dropper is 410mm. Great, that's 30mm shorter than a Reverb 150mm. Hang on a second though, that length doesn't include the actuator? So really, the OneUp is more like 440mm with the actuator? @OneUpComponents what am I missing here?
  • + 1
 hmm, this is a good point. I guess it depends on the bike - some may have a pivot bolt right below their max insertion point, others might not. if you have nothing obstructing just below, then the effective length is 410, otherwise, yeah, it's probably closer to 440 like all the other posts
  • + 6
 We compared all post without actuator length. Our actuator is quite short at 32mm but more importantly it is small diameter and centered on the post. FYI - the Reverb 150x440 is more like 480-490 with actuator.
  • + 1
 @OneUpComponents: the 150mm post would require me to use the entire max insertion depth of the frame, before adding the actuator. If i try to fit it and it and the actuator bottoms out on something, assuming I don't actually ride on it, could I return it?
  • + 4
 @OneUpComponents, make a 200mm version that has the same total length as the 170mm Reverb Stealth and I will place my order immediately... Please? Don't forget us tall guys. Smile
  • + 5
 First thing I thought when I read "travel adjustable" in the title was: "duh! It's a dropper post!" And then I thought about it again and felt stupid.
  • + 2
 I didn't order because the shims aren't in stock & i'll definitely need one if ordering the 170mm.
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.
  • + 2
 Hi, has anyone any experience with ther customer service and can tell me about it? I'd really like to buy this seatpost (especially since I own their EDC set and am happy with it), but I can't find any information regarding that question, and since I have quite some talent in destroying bike parts, that's an important aspect for me...
  • + 2
 Their customer service is their strength.
  • + 4
 Simpler, cheaper, lighter and good looking on top of that, hell One Up, you make me want to put that Reverb in the BuySell section!
  • + 2
 But does the cable clamp at the post, or does the cable head simply fit in and the clamping is done at the lever?
Edit: Upon actually reading the post carefully, the answer to my question is the right one. Good shit, Oneup.
  • + 1
 Hoping it clamps at the post so i can use my xtr front shifter that is looking for sonething to do!

 @onemind123: It clamps at the remote

 This looks awesome! When my Fox dropper is donezo this will probably be my go-to. Excited about customizing my dropper height. Never quite got my dropper exactly where I want it between fully extended and dropped. One height is always off a tad.

 How long are the gas charged cylinders expected to last? Any other maintenance intervals for the shims? Seal? Bushings?

 Just got my 150mm today. But I can't use it until shims are available May 14th (per website) + shipping time.

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.
  • + 1
 Help! This or a Bike Yoke Revive?? I just want something that works well. It seems like One Up has a lighter option, better warranty and best of all I can get a 170mm without worrying about it not working for me. Also GEEEEZZ it's cheap.
  • + 1
 Hrmmm, tough call. I've got a Revive post and it's been flawless. Nice light action and it slides like a hot knife through butter. This does look super slick too. If I had my time over I'd probably give this a go based on the price, equal weight and equal short length. I could use the 170 too and slam it right to the collar. Enjoy.
  • + 1
 Well the Revive is nearly double as expensive- but is it 2x better?

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

 Want an oh so fashionable 128.99mm drop? You got it!

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.
  • + 1
 My biggest issue with droppers is that they add about an inch of height compared to running a post. I'm talking about its lowest possible seat position. Makes a big difference this doesn't fix that as it still has that fat collar in the way.
  • + 1
 @OneUpComponents From a serviceability standpoint, is the drop in cartridge is a sealed unit? Can they be opened to recharge air/nitrogen or is it like a car strut, once its done it's done? Are the slide bushings replaceable to fix fore, aft and rotational play?
  • + 1
 @OneUpComponents Just installed the Dropper Post today. The Green Actuator can swivel a few degrees left and right. Only problem is I need it to swivel forward and backwards. Can the actuator be rotated 90 degrees to accommodate this? This will allow the dropper to be inserted an extra 1/2 inch as it swivels away from the seattube bend and further down into it. With the actuator as is, the insertion depth (not total stack height) is a more or about the same as a 175mm KS Lev that I tried
  • + 2
 So does this has less stack than a 125mm reverb ?
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..

 It depends on the generation of generation of Reverb.

 @RichardCunningham when is the full review comming? you mention in the article this summer....summer has now gone! any issues? i went out and bought one straight away and its running great. Its interesting that there are barely any reviews on this post since the intial launch. @OneUpComponents
  • + 1
 I like the idea of shortening the cable at the lever, it makes for an easier set up, and the adjustable travel is brilliant, but who knows about durability, I do not really like the idea that they sell a replacement cartridge! I currently use a Revive post and it is flow less, including the great remote lever.
  • + 0
 I was hoping it wasnt at the lever as i wanted to use an unused front shifter for the post duties. Guess i have to go with a fox transfer. Or a ks.
  • + 2
 I hear you but geez man you can just buy two of these for the price!?!? Let alone an extra cartridge. I'm passing on the revive and going with this regardless of price. The adjustable travel (I'm a tall guy) is awesome

 @Svinyard: Actually the revive is just $50 more ...

 I have a bunch of Oneup components on my bike and while some of them are amazing, some of them are a bit lacking (cough cough minidriver). However, they gave me a full refund on any product I wasn't satisfied with and totally stood behind their stuff. Top notch company and stoked to see them put out a dropper.
  • + 2
 What's the recommended interval for the $80 cartridge to be replaced? Is this sealed cartridge filled with unicorn farts or nitrogen?

 The travel length is adjustable, but is the travel infinite like other droppers? (I.e., I adjust the travel length to 128.99mm, but I can still drop the saddle to whatever height within that range.)
  • + 1
 Yes, infinite adjustment within travel range.

 Will be getting. Forget the long-term testing; I'll be your guinea pig. Love me some One-Up.
(My reverb actually works great but has SO much play)

 The only question I have is after a little use is it going to sag under weight like the reverb does? Even with the newer generation with the gold lettering 10mm is an acceptable sag.

 That sucks. That's where the revive post nailed it. You can do an internal air bleed is 5 seconds. Such a nice post too.

 Is it me, or does it look exactly like the wolftooth componentes remote but in carbon? anyway, if it works anything like it then it'll be awesome and a worthy upgrade for any dropper

 Just like any other seatpost: depends on your frame material. Aluminum, steel, or titanium frame? Use grease to prevent seizing. Carbon frame? Either use carbon paste or leave it dry, grease will make it slip.
