We've all lost more than a few small parts in the hectic shuffle of swapping rotors and sorting equipment, and it's always good to have an extra Shimano SM-HB20 Centerlock Rotor Lockring in your toolbox in case the one on your wheel goes missing. Compatible with all Shimano 15mm and 20mm thru-axle centerlock front hubs, this lockring securely holds your rotor in place no matter the terrain.
