Jockey wheel set Ceramic Hybrid CX - Shimano - 9,10 or 11 Speed - Red

Independently tested and winning competitions for the least rolling resistance, the truly best part of these jockey wheels is the silent and crisp shifting they afford. Machined from solid Delrin at our California machine shop, not molded, they are much harder and precise than any competitor's that have copied this design. Where aluminum jockey wheels are loud and deteriorate almost immediately after installing, Enduro Bearings jockey wheels will shift perfectly and precisely a year or two from now just the same as the day you installed them.
