For severe racers looking for smart fat expense advantages and optimized rotating fat, XRAY's amazing optional lightweight 1st gear drive flange created from 7075 T6 aluminum wound up being strategically lightened (compared to the standard #335530 flange) to reduce rotating fat without having to lose energy or durability. Includes factory-pressed top-notch German 1-way bearing, hand-ground for optimum operating precision and power. The 1-way bearing is non-replaceable when exhausted, such that it must be frequently serviced, washed, and oiled frequently (we suggest making use of #309580 One-way Lube). Orange color.
