For serious racers hunting for smart weight savings and optimized rotating fat, XRAY's brand new optional lightweight first gear drive flange made from 7075 T6 aluminum happens to be strategically lightened set alongside the standard #335530 flange, reducing rotating fat without sacrificing energy or durability. Includes factory-pressed top-quality German one-way bearing, hand-ground for maximum operating precision and strength. The one-way bearing needs to be serviced, cleaned, and oiled frequently (we suggest using #309580 One-way Lube). The one-way bearing cannot be changed as soon as exhausted.
