Renthal Grooved Front Sprockets

Renthal grooved front sprockets are simply the finest front chainwheels on the market today. They are designed to offer excellent durability with a lightweight design which delivers maximum power transfer. Each sprocket is CNC-machined from cased hardened and core refined 655M13 nickel chromium steel. Mud grooves are then CNC-machined into each tooth on both sides of these components to allow mud to flow away from the key contact points between the chain and the sprocket. This unique design helps reduce wear and can dramatically increase the lifespan of your drivetrain. Maximize your performance with the ultimate front sprockets from Renthal.

Test results prove that the proprietary liner material used in the Motion Pro T3 Slidelight clutch cables can last for 30,000 cycles with only minimal wear. This gives you a longer-lasting cable that provides consistent, smooth performance long after conventional cables have worn out.
