The OneUp Dropper post is now available in 120mm, 150mm, 180mm and 210mm lengths and all can be shimmed down in travel by 10 or 20mm.
We've been obsessed with shaving every last millimeter from the latest OneUp post to give you the the shortest stack height and shortest total length of any dropper post. No other post can get your saddle lower.
Cable actuated with reliable sealed cartridge internals for easy home servicing and includes travel adjust shims allow you to custom tune your post to dial in your perfect length.
The dropper market is dominated by expensive big brand posts and generic catalog shopped posts with different logos. We want to offer something better, a post with class leading specs, innovative useful features AND real value. Want more from your dropper? Get OneUp.
