The OneUp Dropper post is available in 120mm, 150mm, 180mm and 210mm lengths and all can be shimmed down in travel by 10 or 20mm.

Starting from $199 USD with free shipping worldwide, 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.
