Bicycle Rear Dial Guide Wheel Aluminum Alloy Ceramic Palin Bearing 11-17T

Feature: *It can effectively suppress the horizontal swing of the chain and make the speed change more accurate. *Ceramic bearings are used which are smoother and quicker in response. With the spring design there is no need to worry about the bearings rubbing against the edges and causing abnormal noise. *Two reducing sleeves are given as a gift which is more compatible and can be converted into 4/5MM Palin bearings after installation with flexible rotation *Please check the number of teeth on the original car when purchasing. In principle it should not be greater than the number of teeth on the guide wheel of the original car otherwise it may not be usable.
