XRAY Lightweight Aluminum Drive Flange w/One-Way Bearing (Orange)
This is an optional XRAY Lightweight Aluminum Drive Flange. For serious racers looking for smart weight savings and optimized rotating weight, XRAY's optional lightweight 1st gear drive flange has been strategically lightened (compared to the standard XRA335530 flange) to reduce rotating weight without sacrificing strength or durability. Includes factory-pressed high-quality German 1-way bearing, hand-ground for maximum running precision and strength. The 1-way bearing is non-replaceable once worn out, so it must be regularly serviced, cleaned, and oiled (XRAY recommend's XRA309580 One-way Lube).
