Couronne RENTHAL bi-composant standard - 520

Moto Sprockets The origins of high performance chainwheels in motocross began at the Renthal® Factory in Manchester, UK. By applying the same relentless obsession to perfection we apply to every Renthal product produced, our chainwheels epitomize what a premium motocross sprocket should be. Computer engineered to achieve perfect concentricity and fitment using the highest grade raw materials the earth has to offer. CNC machined with Renthal's iconic 'Ultralight' lightening pattern to reduce weight and disperse chain load. Then finished with surface coatings to reduce wear and increase drivetrain life. Renthal sprockets continue to be the 1st choice to the world's premier athletes and race teams.
