Fits E-sync hubs and includes pawls, springs, pawl retainer, 0.5mm freehub spacer, 1.8mm cassette spacer, and freehub seal. Bearings are pre-installed. Compatible with SRAM XDR style cassettes. SRAM XD cassettes are compatible when used in conjunction with the included spacer. Not compatible with any Shimano cassettes.
