For serious racers wanting smart weight cost savings and optimized rotating weight, XRAY's brand new optional lightweight 1st gear drive flange created from 7075 T6 aluminum is strategically lightened set alongside the standard #335530 flange, reducing rotating weight without having to sacrifice strength or durability. Includes factory-pressed top-quality German one-way bearing, hand-ground for optimum operating accuracy and energy. The one-way bearing needs to be serviced, washed, and oiled regularly (we suggest utilizing #309580 One-way Lube). The one-way bearing can't be changed as soon as worn out.
