New dropper seatpost from OneUp Components

I miss days where I could just go to the physical shop and try things out myself instead of reading contradicting info on i/net

Oneup dropper does NOT feel the same as Fox Transfer in terms of its operation! When you compress Oneup by hand or while riding you can feel that slightly grindy resistance …compressing Fox Transfer is way more smooth and easier in comparison (I can do it with my thumb). It’s hard to explain but it’s instantly noticable and there is abosolutely no way you cannot notice this. The same goes with lever operation. I used the same cable and the same lever (Wolftooth). It takes way more force to move the lever when you have Oneup post. It may or may not be dealbreaker for some but I think it’s important that people know before they part with their money. Even more so considering how often you will use the dropper (imo good dropper makes a night and day difference in ride enjoyment). The same goes with seat clamp torque as per my previous comment – that’s a proper dealbreaker imo.

Whoever says both of these posts (Trasnfer and Oneup) actuate equally smooth is misleading others. This applies regardless of the seat clamp torque and it’s not a deffective unit as I’ve had 2 of them (and if it is than QC is really bad). Some people seem to be blinded by the lower price and/or will take anything that has Oneup written on it.

It’s fairly clear you have a bit of an axe to grind. Not to say you haven’t had an issue with your particular seat post, but as you can see on here, you are pretty much the only one who has, that doesn’t make it gospel though.

I think you will find that was me. Not sure why my post is any more misleading than your claims though. As I said I’m replacing the transfer post on my other bike with another OneUp because I want the extra travel, I (as are many others on this post and other on the internet) mostly happy with our purchases. Mine is as smooth as my Transfer post, and as reliable so far.

For the record, this is the only OneUp thing I have ever bought. I won a chainring at a race once though, if that counts?

Maybe you should just go an buy another Fox post to make you happy again 🙂

Have tried to install my new One Up dropper today, but so far I can’t get the post to drop or rise

On arrival the post was probably half dropped. I couldn’t actiuate the post by hand, but figured once installed cable tension would suffice.

I’ve watched a couple of videos and followed the instructions. Took me a while to get enough clamping force on the One Up remote cable clamp to stop the cable slipping but this isn’t the issue

I checked the pressure in the spring and it’s 285 psi… so bob on

Any tips or pointers from the happy customers on here?

You should be able to do it by hand, but you push up on the collar rather than pull down on the bit the cable attaches too, if that makes sense.

Not sure, i fitted mine and it worked first time and faultlessly since then

So, I can’t get it to move by hand… reckon something might be wrong, but having had it for 3 weeks while waiting for my new frame, I’m loathe to lose any more time

The green ano housing into which the cable goes is very loose… turn the post upside down with the O ring off and it slides in, turn it back and it slides out. There is no resistance. There appears to be something black further into the actuator which perhaps should protrude further to allow me to fit the cable end into it?

Any more pointers before I contact One Up?

It should fully extend if you just push hard on that “housing” (the U shaped but of metal  that is held on by the o-ring. If it doesn’t then I guess it’s bust.

Anyone had any joy contacting One Up directly…. how did you do it?

Not getting any response via email

Can’t find a phone number

Only fair to say that the replacement post they sent me is a joy to use… very impressed based on ease of installation and driveway test ride

Strange they seem to have disappeared from UBYK’s website 🙁

They are still there.  Was literally looking to buy one this morning.

Well, bit the bullet and ordered one of these (170mm, 31.6). Going to shim it down to 120mm and hope it fits!

Also got the Bontrager Drop Line 2x remote so it doesn’t interfere with the Twinloc on the Spark.

Am I right in thinking that you can trim the spacers and get the exact height you desire? Just thinking if it goes all the way down to the collar in the seat tube, I’ll be able to get full extension to my desired height?

Cheers JohnW, it would appear their website it poop on mobile. Google links don’t work and their search is broken!!

Ok looking for some advice, i’ve got a 150mm Oneup post for my new build but it’s come to my attention that the way the post operates Via the cable out requiring to move(as opposed to the the inner like most others) may not be compatible with my new frame. The dropper exit port has a snug grommet and the clamps, ..as per this.

Always seeking minor improvements…. the readily available @rockshox Monarch’s air spring ramps up a fair bit and coupled with the progressive leverage rate curve on the Contour it was a challenge to get full travel unless you rode it really hard or ran more sag. Not really ideal for the lighter more ‘xc’ shock option. This is a different version with the highest volume air spring and a low compression tune, quick test ride reveals buttery performance to full travel at the normal sag levels, it suits the frame perfectly! Quite surprised to see a heap of strava pr’s on my mellow test ride! #rockshox #monarch #testriding

It;s not been used, can be returned…but i’d be struggling to get another 150mm post to fit i think :/ , I would’ve really like more drop.

Should be fine. My FlareMax is pretty similar. Just need to make sure that there is a bit of slack, but that’s just a case of pushing a few mm of the cable into the seat tube to be on the safe side.

Tight grommets on my Orange too, I was gonnna say the same as Roverpig – just allow a bit of slack in the seattube.

but that’s just a case of pushing a few mm of the cable into the seat tube to be on the safe side.

+1 it’s really not a problem.

My Oneup dropper is on a Kenevo where the cable entry is kind of really restricted around the motor. But it  still works really well.

Thanks fella’s, if it dont’ work..im blaming you now 😛

Received mine from UBYK (£166.50 with STW discount) and it looks like it should just fit. I hadn’t realised just how long the post is! It may be the shortest stack height above the collar, but you need a frame with a long seattube for full insertion. 450mm + 32mm for the the actuator gives me about 5mm to spare on the tube and I hope the actuator works because that will be in the kinked part of my frame.

Can’t try it yet until Shimano hurry up and release the E7000 ebike shifter to make room for the dropper lever. Current E8000 shifter is a crap design 🙁

Any more opinions on these posts? Has anyone tried them compared to a Revive? How smooth is it, any reliability issues? Is it best going with their lever or an alternative?

To add balance my Oneup dropper has let me down after 2 months. It loses 50psi a week. From new the travel was never smooth and slowed down towards the top even at the max 300psi. This quickly led to the post not going to the top and stopping where it slowed down. I always felt the tolerances were unnecessarily tight and that the total absence of sideways movement is at the detriment of very high friction but not sure this is related to my issue. A poor product IME and hopefully they’ll do the right thing from a warranty pov

Sorry @riklegge I’ve only just seen this.

I’ve had a Revive and a couple of rides on a One Up. Not a long-term test really, but to be honest they feel very similar in function. The One Up is the first dropper I’ve had with zero movement in the post.

I did have to warranty my Revive though and the replacement never felt as smooth. Can’t really speak on the longevity of the One Up though as it’s staying on the Spark when I get around to selling it 🙂

A bit of humble pie following my recent post : Oneup replied to me within 30mn with the following advice:
– It doesn’t leak but the cartridge is so small, the reading is down to air going into the pump when connected.
– They also explained how to resolve the high friction preventing full return : unscrew the collar, pull out the white insert, grease it, put it back together and move the post up and down 50 times. This has worked so all good, hopefully permanently.

Hope sram adapter, hacksaw and spacer. Solid

Looks like Oneup have brought out a new version with 150 / 180 / 210mm drops:

DROPPER POST – V2

UPDATES:
Shortest total length of any dropper
Shortest stack height of any dropper
New upper DU Bushing in the upper collar
Increased bushing overlap and durability
100-210mm post lengths in 10mm increments.
20g lighter

A new remote also which is made of aluminium.

Annoyingly I just bought the original one about a month ago.

210mm dropper, now that’s a proper dropper post!*

*applicants under 6ft need not apply 😀

Also like the look of their new EDC stem, no need to thread the steerer tube.

I think I might just be able to squeeze the 210mm into my Remedy. I’ve got a 185mm in there already (Bikeyoke) but it suddenly seems shrivelled and inadequate.

If anyone wants a MK1 post there’s currently $30 off the price – so making it around £129 delivered.
DROPPER POST – V1

I had a few problems getting the dropper to move, due to the outer cable housing being used to actuate it rather than the cable.

The bottom of the dropper is close to the exit port on the seatpost, and the cable routing bends tightly. Like dumbbot’s picture.

The moving cable outer was binding on the edges of the exit. First I enlarged the port but that didn’t help much. Then I ground a chamfer on the inside and outside of the exit which has fixed the problem.

The actuation is usable but heavier than other posts – Thomson, BrandX, Reverb.

I also found that, unused over the winter, the actuator got quite sticky and the post lost about a third of its pressure and wouldn’t return to maximum height.

Adjusting the air pressure is a faff as the saddle has to come off to reach the valve, and getting it all together again is fiddly.

Quite easy to check the operation off the bike – press the post down on a flat surface, to depress the green actuator at the bottom.

Apparently OneUp are working on a new actuation mechanism which will use cable movement rather than outer housing, which would be a welcome improvement.

Apart from needed air twice mine has been faultless in past 14 months. Been through all sorts of weather conditions and washed many times.

Hard to fault. I find it super smooth and has the least amount of play of any dropper I have tried. It’s also the only 150 dropper I could fit in my frame.

New one is out in June, but until mine proper breaks I feel no need to change it!

@dumbbot – did this dropper work on your Swarf in the end? Just ordered the same frame and was thinking of getting this dropper.
