Spend less, drop more, no bleeding and a better remote.

OneUp has released the (claimed) world’s shortest, long travel dropper. The new post is said to allow you to maximize the travel you and your frame can handle and it comes in at a very competitive 248 USD. Bang for your buck seems to be a mantra with OneUp and the new post offers a range of interesting adjustability and free shipping worldwide. You can choose the post without remote for 199 USD. If you like OneUp's remote and already have a cable dropper you're happy with, it can be purchased on its own for 49 USD (includes cable, housing and either I-Spec-II, MatchMaker or bar clamp).


  • Available in 170mm drop (tuneable to 120mm) and 150mm (tuneable to 100mm). 
  • 30.9 and 31.6 diameter 
  • Cable routing is internal only
  • Weight: Post, remote, housing, and cable from 595g (150 x 30.9mm). Remote from 32g (I-spec II)
  • Stack Height (collar to rail): 170mm is 207mm and the 150mm is 187mm
  • Effective Length (Total length without actuator): 170 is 450mm and the 150 is 410mm
  • Min Insertion: 170 is 110mm and 150 is 90mm
  • Full range of service parts available. 

OneUp Dropper Post Base

OneUp says that more drop equals more fun, and who are we to argue?  Another claim is the post delivers the smallest stack height for a long travel dropper. More people will be able to fit a larger drop post into their bikes, and with more drop you can get that seat further out of the way on the descents. 

One of the most interesting feature is tunability. 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. So if you want an oh so fashionable 128.99mm drop, you've got it! It will also allow you to run the maximum amount of drop available with your frame, up to a full 170mm. The tuning can be done on-bike, tool-free, and without removing the saddle or touching a shock pump, which is pretty incredible on its own. The team also mentioned that lowering the post travel increases bushing overlap, which is great for heavier riders.

A carbon remote with oversized bearing and super smooth action is also part of the new post, but also available separately. The unique lever position allows you to keep a stronger grip on the bars while actuating your post. The OneUp lever mimics your R/H 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.

With a simple and reliable cable actuated remote you'll never have to bleed your dropper remote again. The cable 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.

The post is available now at and at good bike shops worldwide.

Yeah, nice to see another option, sad to see it only comes with a fixed straight head, no offset option for those of us who don't only pedal straight up to enjoy the downs and like to do more than spin the easiest gear on those climbs and need one to fight the modern stupid STA trend, which goes hand in hand with the flow trail crowd :-\ Guess I'll just be happy with my 9point8 FallLine and offset head

Nice to see more players in the dropper post field!  I wonder if this is a OneUp design or if it is a re-branded/re-licensed design from someone else?  Giving the full length of the post (without giving the length of the actuator) isnt all that helpful.  Maximum insertion has to take the actuator into account, so it is a required measurement for proper fitment.
Ill be interested to see if the shim design works as advertised, cool idea for sure.
