Product description
Renthal off-road front chainwheels are chosen by more factory motocross and supercross teams than any other chainwheel on the market today They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel Utilizes mud grooves which are CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the chainwheel This helps reduce wear and increases the drivetrain lifespan
