DT Swiss Ratchet LN Aluminum Freehub Upgrade Kit (Black) (36T) (SRAM XD)

DT Swiss Ratchet LN Aluminum Freehub Upgrade Kit Description: This DT Swiss Ratchet LN Aluminum Freehub Upgrade Kit converts the 370 series rear hubs and select DT Swiss rear wheels equipped with a 3-pawl freehub driving mechanism to the beloved DT Swiss Ratchet drive system. This upgrade will produce a 10deg engagement within the drive mechanism due to having double the contact points than what is typically found in a 3-pawl hub or even an 18t ratchet drive; this faster engagement will enable a rider to more easily position the pedals when cranking uphill and taking on technical sections of the trail. Best of all, this drive mechanism produces minimal pedal kickback, will maintain excellent durability, and require little maintenance to keep the good times rolling.
