For serious racers selecting smart weight savings and optimized rotating fat, XRAY's optional lightweight second gear provider created from 7075 T6 aluminum happens to be strategically lightened compared to the standard #335520 provider, reducing rotating weight without having to sacrifice energy or durability. Includes factory-pressed ball-bearing. The ball-bearing must certanly be regularly serviced, washed, and oiled, but cannot be replaced when worn-out. Orange color.
