Renthal Ultralight rear chain wheels are manufactured to extremely tight tolerances from a special material developed to withstand the rigors of Supercross, Motocross and Enduro.
The 7075 T6 aluminum alloy rear chain wheels are 66% lighter than steel, yet incredibly durable. Which reduces the power required to accelerate and brake unsprung revolving weight, resulting in improved race performance
Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life
Renthal's combination of a very high strength base material and an exceptionally hard wearing surface result in significantly increased chain wheel life
