For serious racers finding smart fat cost benefits and optimized rotating fat, XRAY's unique optional lightweight 1st gear drive flange created from 7075 T6 aluminum is truly strategically lightened set alongside the standard #335530 flange, reducing rotating fat without the need to sacrifice power or durability. Includes factory-pressed top-quality German one-way bearing, hand-ground for optimum performing accuracy and energy. The one-way bearing must be serviced, washed, and oiled usually (we recommend making use of #309580 One-way Lube). The one-way bearing may not be changed whenever exhausted.
