From XRAY:
For severe racers on the lookout for good weight financial savings and optimized rotating weight, XRAY’s non-compulsory ultra-lightweight 1st gear drive flange created from 7075 T6 alu has been strategically lightened to scale back rotating weight with out sacrificing power or sturdiness. Includes factory-pressed high-quality German 1-way bearing, hand-ground for optimum working precision. The 1-way bearing is non-replaceable as soon as worn out, so it have to be often serviced, cleaned, and oiled often (we advocate utilizing #309580 One-way Lube).
