"I rebuilt a thoroughly under-serviced dropper with the parts from OneUp, and now it functions like new again! Heads up: the updated madcap assembly is a tight fit on the V2 stanchion. In order to install it, I had to work the seal back out once it was pressed on. No worries."
— Sam A. (5/5)
"I feel the One Up dropper is the best on the market. Being able to give it a refresh at such a low cost is amazing."
