Reviews

The V3 Dropper Rebuild kit

"The V3 Dropper Rebuild kit updates the old V3 Dropper 1-piece upper bushing to the new V3.1 Dropper 2-piece upper bushing ... Certainly worth doing IMHO ... Very easy install according to my LBS ... Thanks OneUp !!!"

— Jim R. (5/5)

So easy to get like-new performance from V3 dropper post with rebuild kit

"The OneUp V3 dropper rebuild kit is so easy to do, took me 45 minutes working slowly while being distracted. I use my dropper at least 200 times per ride, so the rebuild as necessary after about 200 hours of riding. After the rebuild the dropper is tighter, smoother, and easier to control, just like new. This is for a 210mm dropper that started out on a 2023 Trek Fuel EX size M/L, and now it is going onto a 2025 Trek Fuel+ EX size medium."

— Jeff A. (5/5)

Replaced the dropper pin kit

"Replaced the dropper pin kit with the oversized pins. Used the thickest ones to correct play on my V3 dropper. Corrected the excessive play enough to not notice there was play while riding. Highly recommend to do when performing maintenance."

— Alfredo L. (5/5)

Great service and upgrade kit - thanks OneUp

"Great kit to get your V3 dropper up to top notch shape with updated internals. Don't really remember the exact name for all the parts but the instructions made it all so easy that doing the work yourself didn't mean taking all day. I did watch the video twice before the service kit arrived so when it did I could get started right away. I had no issues with any part of the service."

— Paul H. (5/5)

parts were as expected. this

"parts were as expected. this provided a much tighter fit to the original parts. i actually had to go with the 2 notched pins rather than the 3 notched pins as they were too tight. other than that, great cheap solution to rebuild a great dropper post."

— Kraig K. (5/5)

On time

"Part arrived on time."

— DANIEL P. (5/5)
