The #1 chainwheel in motocross & supercross

Renthal Ultralight Chainwheels are chosen by more Factory Motocross and Supercross teams than any other brand on the market. Our rear chainwheels are CNC machined to offer the greatest concentricity and optimum tooth profile for increased life and durability. Through the CNC machining process, we are able to create an extremely lightweight rear chainwheel which reduces revolving unsprung weight and increases the power transfer to the rear wheel.
