The Kink Universal Driver Hub Guard is made from chromoly for maximum strength and long lasting durability, featuring an anti-rotation tab to keep the guard from spinning and an open ended axle slot for easy installation. Helps protect the hub flange, spokes and driver from damage caused by drive side grinds and is thinner than typical aluminum guards as to not affect the rear end spacing. Universal design fits most 14mm rear hubs. (2.2 oz) Note: Universal type hub guards will not work with most 14mm female axle hubs that use 3/8" axle bolts. However, if the hub uses 14mm female axle bolts, it should work fine.
