Daily Grind Infinity Hub Guard Description: The Daily Grind Infinity hub guard features a redesigned shape to fit more 14mm rear hubs while maintaining maximum hub and spoke protection. The Infinity guard is CNC machined from 4140 chromoly for maximum strength and is designed to slide over your existing non-drive side hardware. (5.7 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.
