For severe racers looking for smart weight savings and optimized rotating weight, XRAY's optional ultra-lightweight 1st gear drive flange produced from 7075 T6 aluminum has been strategically lightened to lessen rotating weight without having to sacrifice power or durability. Includes factory-pressed high-quality German 1-way bearing, hand-ground for optimum running precision. The 1-way bearing is non-replaceable as soon as exhausted, so it must certanly be regularly serviced, washed, and oiled frequently (we recommend using #309580 One-way Lube).
