The OneUp V3 is built to make more room for dropper travel. A short overall length and low collar help you fit a longer drop into a frame that might otherwise force a compromise. Travel can then be reduced by 10mm or 20mm with the supplied shims, so you can get the saddle height right rather than settling for the next size down.
Low-friction IGUS bushings and an SKF wiper seal help the post move smoothly. The sealed cartridge doesn't need you to top up its air pressure, and the post can be stripped for service with common workshop tools. That makes the V3 a useful option for riders who want plenty of saddle clearance and straightforward upkeep.
Measure before choosing
Check your frame's seatpost diameter, maximum insertion depth and the distance from the seat collar to your saddle rails at pedalling height. Travel alone doesn't tell you whether a post will fit. The 27.2mm version is offered in 90mm and 120mm travel; larger diameters have a wider range.
Travel reduction: 10mm or 20mm using the included shims.
Compressed stack height: 30mm, or 25mm for 34.9mm posts.
Seat clamp accepts 7x9mm and 7x10mm oval carbon rails.
Supplied with a cable barrel end, light suspension grease and two sets of 10mm travel-reducing shims.
Remote, bar clamp or adapter and coloured thumb cushions are sold separately.
A short overall length and low compressed stack help fit useful travel into limited seat-tube space. The included shims let you trim that travel by 10mm or 20mm to get your pedalling height right.
Smooth movement where it matters
Low-friction IGUS bushings and an SKF wiper seal support smooth movement as you lower and raise the saddle. The sealed cartridge takes air-pressure top-ups out of normal ownership.
Keep servicing manageable
The V3 is designed to come apart at home with a 14mm spanner and 2mm and 5mm hex keys. Replaceable service parts let you maintain the post as a working component, with the official instructions guiding each job.
