Product Information
Renthal Sprockets for Marchesini, OZ Racing and BST Carbon aftermarket rear wheels are ultralight, hard-anodized and manufactured to extremely tight tolerances. 7075-T6 aluminum alloy rear chainwheels are 66% lighter than steel, yet incredibly durable. Advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and
long-life. The combination of a very high-strength base material and an exceptionally hard-wearing surface results in significantly increased chainwheel life.
