For serious racers looking for smart weight savings and optimized rotating weight, XRAY's new optional lightweight 1st gear drive flange made from 7075 T6 alu has been strategically lightened compared to the standard #335530 flange, reducing rotating weight without sacrificing strength or durability. Includes factory-pressed high-quality German one-way bearing, hand-ground for maximum running precision and strength. The one-way bearing must be serviced, cleaned, and oiled regularly (we recommend using #309580 One-way Lube). The one-way bearing cannot be replaced once worn out.
