OneUp has added two new options into their dropper post lineup - a 240mm post and a 90mm post. When combined with the 20mm of travel reduction that's possible via shims, it means there’s a OneUp Dropper option available in 10mm increments from 70mm up to 240mm of drop. The 90mm post is there to cater to XS bikes, kids bikes and gravel bikes, as well as bikes that have interrupted seat tubes that inhibit more traditional, longer posts.
The 90mm post is priced at $199.50 USD, the 240mm is $229.50, and the Remote is $59.50. Their weights, in 30.9mm diameter, are 435g and 570g for the 90 and 240mm options respectively. The Remote weighs 41g. The 240mm post is available now via their website and the 90mm drop will be available later this summer.
All posts share the same removable and replaceable sealed cartridge, which sells for $60 USD should you ever need to replace it and a two-year warranty. If you're unsure of how to maximize your post-drop you can use the guide on OneUp's website
Bigger doesn't always mean better, but when it comes to dropper seat posts a larger amount of travel tends to make for a better ride. Concerns about weight to one side, there aren't really any drawbacks to having a generous helping of drop.
We are of course limited by factors such as our own leg length and the bike that we ride when we choose our seat posts. When going for longer drop we can also have the issue of the saddle height being too high and full extension. There is also the added complication that as our posts get longer there is also more flex going through them. This is exacerbated when run with a slacker seat tube or taller, heavier riders putting more stress through the post.
OneUp has been tackling the first two of these issues with previous generations of their Dropper Post. The post has, they claim, the shortest stack heigh and the shortest total length of any post with the same travel. They also offer small 10mm shims to fine-tune the amount of travel to your need, with the reduce the amount of travel by 20mm.
Changing the travel is easy and tool-free. The shims are provided with the post.
The last issue, which is particularly relevant as the new post goes all the way up to 240mm of stroke, is the problem of flex. They address this by having increased bushing overlap to help keep the post stiff even when loaded and at full extension.
At 183cm, or six foot, I can just
about fit 240mm of travel on my 120mm, low slung bike without needing to shim it down. I'm looking forward to seeing how the extra drop affects my riding, as well as its long term durability.
But 240mm will do nicely for now. I think I just set a new personal record for shortest time between "learning a product existed" and "deciding to spend $200". Meaning, I have been waiting for this to exist for a very long time. Thank you OneUp!
Either way this product is a big win for tall people.
Interesting to see the variety in seat post heights. Some real clydes are stuck with really long seat tubes, while Henry reports having an amazing amount of room for a long travel dropper on a 120mm frame.
This makes me think, I know that people at the extreme ends of the heigh spectrum make up a really small portion of the market, BUT, since there are little/no options in those size brackets, whoever introduces products designed for those extremes will instantly corner that ENTIRE market.
I can't speak to what it's like for people who are much shorter than average, but as a very tall rider, it's so difficult to find frames that are big enough. Very few brands carry XXL sizes, and those that do seem to use it as a way to reduce the gaps in their intermediate sizes. For example, Santa Cruz makes XXL, but it's marginally bigger than most brands' XL offerings.
Nicolai/Geometron is one option, but not everyone wants to (or can afford to) import a very expensive aluminum frame from Europe, especially one that makes so many compromises in the name of speed/traction.
Currently I'm riding a frame built for someone four inches shorter than me. Imagine being 5'9" and riding a bike for someone who is 5'5"! My bars are 75mm rise, I just bought an admittedly silly looking 240mm dropper, and I actually run my saddle pushed BACK against the rails so that I can get a little extra reach when seated. I would kill for like, 560mm reach, 700mm stack, and 480mm rear center.
And don't push your saddle back for length, that's terrible for climbing performance, use a longer stem to get cockpit length.
Geometron is waaaaay worth it.
It will be faster. It is wild fun in mullet setup.
You have room to size up and down all the way to 6'7.
Honestly I'm a hack of a rider and destroy bikes. Geometron has lasted me 2 years with no issues except a fair few derailleurs and carbon rims. Bearings still great. Taken some chunks out of it and it's still great.
Ride constantly up Mt Prevost and still not cracked it.
It's marvelous just having something metal and very well made.
Honestly tall people shouldn't look anywhere else. And I'm only 6'2 on an XL.
I feel like most riders like the most drop possible almost like a BMX but a lot of pro DH riders actually have their saddle surprisingly high. There's no right answer!
What I don't get is how people ride with the seat so slammed, on my DH bike my saddle rests on the inside of my thigh which is perfect, so thats exactly where I want it on my trail/enduro rig.
Only time you'd ever what it lower is for dirt jumps if you're banging out tricks, which the average rider won't be doing.
This seems great for those in 6'+ relm.
I'd like to put 190mm dropper on 4X frame with 100mm travel (which I use mainly for commuting) to have more fun during transports but I feel so sorry to drill a hole into the frame.
-13% price for 62% less travel !
Short legged people got robbed !
People just love to make up shit to bitch about... it's so weird.
It’s these no-skill Gumbys that have stifled bike design. Glad most modern bikes have geometry and parts that work for actual hard off-road use.
It's a 175mm dropper for that matter. Travel of the bike is 140mm only and the shock is not even bottomed out. I already explained in another post here. There's are enough bikes where it'll work, no doubt. But one should at least have this in mind...
As for @calmWAKI you answered your own question as like you said, your tire is higher than the seat, the point of a dropper is so you can get low and back, you don't need a dropper that big since you should not need to be occupying the same space as your rear wheel. I used to have a Bardino and at basically the same height as you I used a 125mm dropper and never had an issue getting behind the seat. The stack is so massive on that bike that you feel like you are elevated up on a platform, needing your ass 170mm lower wasn't really a concern as you will look like you are riding a chopper. I would like to see a picture of you with your body as far low and back as you can go with that post, your entire body will be below the bars.
When I had 125 on my Antidote CJ I had a hardtime jumping it on steep jumps as the seat was bumping me in my ass all the time. If I adjusted my positon to a more forward one I was blowing through the jump with little air. On steeps if you don't stay more forward than you think you should then you MAY be doing it wrong.
And that's exactly the problem. As we are not only learning from this thread, people are trying to maximize their drop. And short seattubes and long insertion may suggest that this is possible. But I bet you - because I can tell you from experience - that barley anyone thinks about the saddle clearence until it's too late.
The question is: What really is the point of such a short seattube on this specific bike in the link above? You can not use it. And this is an honest question that I have been trying to answer myself for a long time.
Also - to get back to your original point: This bike in the picture with a 185 Revive would result in saddle rail height of less than 600mm and that is easily lower than what most typical S riders have.
I have a saddle rail height of about 730mm and I'm about 185cm tall. Of course they will attempt to install 180mm (and more) drop, if the seattubes is short enough with enough insertion.
So we are far from extreme regarding the drop. There is room for even longer droppers on this bike (neglecting tire clearence). We have checked insertion.
The problem is that everyone is asking for more drop, but not thinking about consequences.
I would go as far as saying that designing a Medium 29er with more than 120mm of travel, with stays shorter than 440, proper shock length, water bottle and 210mm dropper is impossible. But it is banging the head against the wall, everyone wants more megapixels, more cameras in their phone and in the end the bulk of ignorants with unrealistic expectations are dumbing down the bike design.
Now... let's wait for a Nicolai owner to chime in hahahaha... I'll throw a water bottle at him
So... whoever is heading for 300mm dropper I have a solution:
The question is: Would it not make sense to push/implement 34.9 on a wider scale in the market, and then go longer? Because function and reliablilty - and that, I believe is clear for everyone - will for sure not improve with longer drop. Our 125mm REVIVE is much more smooth than a 213 for example. Everyone can feel it. The fact, that the longer drops are naturally also riddenr by heavier riders make it even worse. If we see troubles on our droppers, then these are concerning more the longer drops - naturally.
The 34.9 standard opens a whole different world and posts are getting much stronger, more reliable, and you can go even longer without having to compromise too much.
I am afraid of going longer than 213 with one of our 30.9/31.6 designs, that's why OneUp has all my respect.
Let me introduce to everyone:
THE DROPPED DONUT! Literally the most trendy frame out there
@brianpark @mikelevy make it happen
The idea is not that weird, as if someone would not think it can make sense.
And also: No water in the seattube. Big plus! ;-)
BTW I use your condom to keep the water away from the seat tube, works ace! Brilliant little thing. Will soon buy your seat clamp so that is fits in better.
And @calmWAKI, so you need a huge dropper on your Bardino because you are using it as a DJ bike, that doesn't mean that bikes in general are not designed properly for long posts.
Both of you are using your bikes/post outside of what the bike was designed for, the Bardino is not a DJ bike (still cool) and the Switchblade was not deigned to have the 185mm post slammed into the frame, it was clearly meant to have it a couple inches higher so its 1. Usable for the rider and 2. doesnt hit the frame.
It doesn't matter if this frame with a 185 REVIVE has a 600mm saddle height, or lower or higher. Or if that saddle height is more or less than what the average "S"-rider needs for that matter.
The point is that there will be customers who will slam the post all the way into the frame, because they want to maximise their drop. And at that point, it doesn't matter which length the dropper has or what is the extended saddle height is, because they are all the same, when dropped.
There will be contact between tire and saddle at full rear wheel travel. I don't want to make a big deal out of it., becaue it isn't to me. I just don't understand the point of such a short seattube if you can not utilize it. Ano the majority won't check such clearences.
Oh, this is a size Small fame. There is an even shorter (-25mm) seattube available.
Yes people want to get the biggest dropper they can use, but if you are going to choose to use a post that drops your seat into your tire then you're a dumb ass.
Its like saying that its stupid to make 2.6" tires because a lot of frames don't clear them but people want the widest tires they can get. Then you post a picture of a 2.6" tire rubbing on your frame as your argument. The solution is that you use the most appropriate tech that still fits your need. Same applies to a dropper, don't buy one that drops your seat into your tire.
I have tried to explain in my last post:
You do not have to use a 213 dropper (or any maximum length dropper) to cause this issue. The same will happen with a 100mm dropper of the same model (Transfer in this case). The compressed stack height of a 100mm Transfer is exactly the same as which of a 175mm Transfer.
So, as soon as you insert any Transfer of any length into this frame, you will get the same result as seen in the picture. Doesn't matter if 100 or 125 or 150 or 175, ...
So if I can not insert the post fully into the frame, without causing collision, then how exactly am I really able to utilize the shortness of the seattube as you say? I don't get it. Sorry.
I have a 370mm seattube, but it is useless, because I can not insert all the way. That means it would not make any difference if the seattube was let's say 390mm or 400mm long, whereever the tire does not cause any more collision. The extra short 370mm seattube length are of no use. Am I wrong?
What planet am I on right now that we can't understand this?
You are contradicting yourself in every single post but I don't know how to explain.
You say yourself, that it is correct that "any length post, if slammed to the frame will hit the tire." Those are your words!
If you can not drop any post to the last 2 or 3 centimeters to the frame anyway, then please explain to me, what is wrong with designing the seattube in the lenght, where this exactly can not happen aynmore? Nothing is lost. For no one.
But, and that is the key point: You avoid potential and very expensive complications due to misuse from the start.
Of course it is not possible to design every frame always for the shortest stack height dropper to the millimeter, because dropper dimensions and lowest stack heights change constantly. Saddles are different, too. But we are not even close to being clear of the tire. We are looking at a dropper with almost 60mm stack height and a frame which is not even the shortest of it's family. So things can be much worse.
Not sure if you now understand what I mean, but if not, then I will not comment anymore. I also don't think it is fair to be rude. I felt this was a normal and fair technical discussion, no need to get personal or start "screaming".
So a bold move by Sacki to come an comment here since sooner or later everyonewho comes here gets covered in crap by cowards without face.
"Not by coincidence our 185 already has a significantly longer bushing overlap than a 210 OneUp or our 213 has more than the 240 We trade build length for something else that we think is more important in our books. That doesn't mean we're right, but it means we set different priorities. You can not have everything. And the customer can choose what is important for him. Or OEs can choose what is more important for them."
This is false:
- The OneUp 180mm dropper has MORE bushing overlap that the Bike Yoke 185mm
- The OneUp 240mm dropper has MORE bushing overlap that the Bike Yoke 213mm
Wouldn’t go back to a shorter dropper.
Love how easy it is to service the OneUp. Love their customer service.
Concave pedals, on the other hand……
Seriously, OneUp stuff is great and this is good to see. I do predict some confused folks taking their bikes in because they're bottoming out harshly and also their saddles are all torn up for some reason.
Funnily, I started a survey last week on another platform to discuss with customers about the need and wish for leven onger drop droppers.
Already back in 2020 I tried to explain to some customers that it is not as easy at it seems to get a long dropper to work on their bikes.
1. You need to have sufficient length of extended post, which is already not easy, but manageable with quite some modern short seat tubes.
2. What makes it more complicated - and what most customers underestimate - is, that insertion is also limited and that is most of the time the bigger dealbreaker than the required extened length. The post needs to go a looong was down the seattube.
3. Now if you managed to take that hurdle, you may also want to check, if your saddle won't drop too deep, as you can see in the picture below:
Now that frame is not even the smallest of its kind (there is even a size smaller) and the old Transfer installed there is not exactly know having the lowest stack height. A OneUp slammed fully into that seattube instead of the Transfer, and the saddle would almost be 20mm lower than what can be seen there.
And we haven't even talked about that we're only looking at 140mm rear wheel travel here with the saddle nose pointed slightly down and the shock not bottomed out.
So there are a lot of things to consider with ultralong drop dropper posts, that one might forget on first sight.
So bottom line for me is, that the majority of people who will benefit from such long droppers are customers that are really tall with a seattube around 450mm or longer for Enduro caliber rear wheel travel. And those long guys are then usually not the lightest riders either, so we'd also have to think about heavily increased structural integrity.
I am sure the guys at OneUp have done a lot of homework to get this dropper done, so chapeau from my side, if it works as intended! I am not sure if I want to keep playing the chaser for the longest drop. Getting our 213 working as it does, already costed us some headache, but I am happy with how it performs now.
We already have overly long clavicles putting increased forces on shocks which are there because people want as much room for as big water bottle as the frame can take. Then the trunion mount thing that was supposed to solve that and fell a bit short. Some designs already have leverage ratios higher than optimal due to low standover and room for water bottle because there is no way to fit the longer shock. Finally the low swung downtubes proceeding forward for a good deal, being put at bit more risk of getting smashed as Bash no longer protects them. Yeti comes to mind first.
The problem now (and always has been) is that my bike and every other complete bike already has a dropper. It's time for more brands to make their build kits customizable or just leave fitament components out of the build all together like pedals. I'd like my next bike to come without a dropper, pedals, saddle, grips, stem, cranks, rotors, brake pads, bar, or tires. Basically, bikes should come with just the main expensive parts like frame, suspension, drivetrain, wheels, and brakes in order to gain some cost advantage. Everything else I'd rather replace, but it's hard to justify the cost when the other stuff does still work.
This is not true. Each length of post has it's own length cartridge.
Now, if some clothing manufacturers would listen and make some decent riding pants in 36" - 38" inseam, I'd be golden!
Thanks for the answers dudes!
At my saddle height i'm sure this thing would work in plenty of frames.
im 6ft and will easily be able to slam a 240 on my large altitude.
People keep whinging about seat post length and for whatever reason brands are b.s'ing that number by putting a huge trek/dh bike bend in the seat tube and claiming short lengths
However, there may be other priorities one may have, when designing a dropper post. Not by coincidence Fox's lower tube of their 200mm version is significantly longer than OneUp's 210mm version. Not by coincidence our 185 already has a significantly longer bushing overlap than a 210 OneUp or our 213 has more than the 240 We trade build length for something else that we think is more important in our books. That doesn't mean we're right, but it means we set different priorities. You can not have everything. And the customer can choose what is important for him. Or OEs can choose what is more important for them.
People also need to know shims exist and are very helpful for running a smaller diameter dropper in a larger tube size.
Weapon of choice must be a dedicated 34.9 dropper, because they work so much better. Not sure if the new 34.9 from OneUp is a dedicated 34.9 dropper or just a 30.9/31.6 with a bigger lower tube, but same upper tube.
The idea behind running a shim is you "CAN" get away with a longer/deeper insert depth post on some frames, ie running a 31.6 post in a 34.9, you can sneak a bit more in.
Oneup will always be my dropper choice, even just for the price, im not paying a heap for an air tube that makes my seat go up and down.
The main issue is that 30.9 and 31.6 are still the most commonly used diameters. 34.9 is the way to go.
Kudos to Ghost and their Riot for that! If they release a link that improves the kinematics, i'm buying that bike.
Eightpins + Formula suspension and brakes + Shimano drivetrain for 3600€ ($4057)? Yes, please!
And for 150€ more you have the option of going coil front and back.
I was replying to @Hairymountainbeast with my first comment, but effed up, ha!
Now, SRAM, please....will you stop messing around with flight attendants and release a 200mm travel AXS post, with a smaller battery?????
But that 240mm, Holy Moses!
I also seem to remember PNW & Brand-X make longer 27.2 droppers.
I have two.
She currently has a Brand-x 70mm that works great. Was going to get her one a bit longer and give the 70mm to her brother.
For me easily sufficient, still riding two excellent revives with 185mm. Asking out of interest.
I am personally seeing too much trouble with such long extension and a 30.9 chassis.
But longevity (also longevity in the mid) also matters a lot. I run a PNW post now and I know people who run TranzX or Bontrager and their droppers work perfectly fine as well after muddy rides. Whereas all my friends who use cheap droppers (ie ZTTO Zoom), and their droppers normally need frequent servicing or just fail annually.
all my 200 $ droppers are very much worth their price and have no problems with muddy or rainy conditions.
