Profile Driver Shim

The Profile Driver Shim at J&R Bicycles is a small part with a big job as it is designed to fit between the driver and hub body to prevent it from grinding. Made from high-strength steel and only .025" thick, it is built for durability without adding much weight. Made for use with all Profile and Madera hubs.
