For serious racers looking smart fat expense advantages and optimized rotating fat, XRAY's amazing optional lightweight first gear drive flange produced from 7075 T6 aluminum ended up being strategically lightened (set alongside the standard #335530 flange) to cut back rotating fat and never having to lose energy or durability. Includes factory-pressed top-notch German 1-way bearing, hand-ground for optimum running accuracy and energy. The 1-way bearing is non-replaceable whenever exhausted, so that it must be frequently serviced, washed, and oiled often (we recommend utilizing #309580 One-way Lube). Orange color.
