For serious racers selecting smart fat cost benefits and optimized rotating fat, XRAY's optional lightweight 2nd gear provider created from 7075 T6 aluminum is clearly strategically lightened compared to the standard #335520 provider, reducing rotating fat while not having to lose energy or durability. Includes factory-pressed ball-bearing. The ball-bearing should really be usually serviced, washed, and oiled, but cannot be changed whenever worn-out. Orange color.
