Renthal Grooved Front Sprocket

Renthal grooved off-road front chainwheels are designed to offer a long lasting front chainwheel in a lightweight design which offers maximum power transfer.

They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel.

Mud grooves 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.

Renthal Ultralight Rear Sprocket

Renthal Ultralight™ rear chainwheels are manufactured to extremely tight tolerences from a special material developed to withstand the rigours of supercross, motocross and enduro racing.

The 7075 T6 aluminium alloy rear chainwheels are 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life.

Renthal's combination of a very high strength base material and an exceptionally hardwearing surface result in significantly increased chainwheel life over other brands.

Renthal R3 MX O-Ring Chain

A premium high strength sealed ring chain with excellent impact load resistance designed specifically to withstand the stress found in offroad applications where an o-ring chain is desired.

This chain is the choice where a combination of high strength, lightweight and maximum power transfer are important considerations. The nitrile o-rings help extend the chain life by retaining the special vacuum injected grease near the critical pin area.
