OneUp Components V2 Dropper Post 120mm ∅30.9mm

It's rare to see a mountain bike these days without a dropper post on them. Dropper posts are widely regarded as one of the best upgrades riders can do for their mountain bikes. With so many brands out there making dropper posts now, it can be difficult to choose the best one. The OneUp Components Dropper Seatpost is the second version of their dropper post. It is available in 120, 150, 180, and 210 mm lengths and they can all be shimmed down in travel by 10 or 20 mm. OneUp designed the post to provide riders the shortest stack height and the shortest total length of any dropper post which means you can get your saddle even lower. It features cable actuation and reliable sealed cartridge internals easy home servicing. It includes travel adjust shims so you can custom tune your post so you can dial in the perfect length.
