OneUp Components Dropper Seatpost

The OneUp Dropper is engineered for the lowest stack height and shortest total length of any post available. This design allows it to fit into frames with limited seat tube clearance where other posts simply won't fit.

Thanks to updated internals, including high-quality SKF seals and IGUS bushings, the service interval is 350 hours. This is significantly longer than many competitors, meaning you spend more time riding and less time in the workshop.

Yes, the post features an infinitely adjustable travel mechanism. You can stop the saddle at any point within its 120mm range, allowing for precise positioning regardless of the terrain.

You must check your bike frame's seat tube diameter before purchasing. While 34.9mm is becoming more common on modern enduro and trail bikes, it is not a universal standard, and using the wrong size will prevent installation.

A shorter total length allows you to run a longer travel post on a frame that might otherwise restrict how far the seat can be lowered. This gives you more clearance for technical descents and better handling confidence.
