Manufactured to extremely tight tolerances from a special material developed to withstand the stress of Supercross, Motocross and Enduro. 7075 T-6 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. Combination of high-strength base material and hardwearing surface result in significantly increased chainwheel life. Self-cleaning mud grooves help prevent dirt build-up.
