Renthal Grooved Front Sprocket
- 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.
- Machined self-cleaning mud grooves at each tooth to help increase wear resistance
Renthal front chain-wheels are simply the finest front chain-wheel on the market today. Our Front chain-wheels feature a specially developed nickel-chrome-molybdenum steel which is case hardened and core refined to give the ultimate combination of strength and hardness. Grooved chain-wheels have cut outs at the bottom of the tooth to allow the escape of mud that would otherwise be trapped between the chain-wheel and the chain. Allowing the easy escape of the mud prevents tension being placed on the chain and the resulting accelerated wear.
