For serious racers looking smart weight cost savings and optimized rotating weight, XRAY's optional ultra-lightweight 1st gear drive flange made from 7075 T6 aluminum is strategically lightened to cut back rotating weight without sacrificing strength or durability. Includes factory-pressed high-quality German 1-way bearing, hand-ground for maximum running accuracy. The 1-way bearing is non-replaceable as soon as worn out, so it must be frequently serviced, cleaned, and oiled regularly (we suggest making use of #309580 One-way Lube).
