The OneUp Components Dropper Post Rebuild Kit V2.1 kit includes all the parts required to rebuild your V2 dropper post and is an updated rebuild kit for V2 posts, which includes an improved midcap assembly with ultra-low friction SKF seals, upper and lower bushings and anti-rotation pins.

• OneUp has found that ~95% of posts with slow top-outs were caused by low air pressure. Please check this first and do so with the post fully extended. Proper air pressure is 280-300psi at full extension, and the valve is located under the top clamp
• If you are still having slow top out then there is a possibility that the upper white bushing needs replacement. This will be evident by the original bushing being difficult to reinstall after being removed
