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 Twinring

A long lasting durable off-road sprocket developed over 5 years.

The unique flat face design keeps weight to a minimum and means the Twinring rear chainwheel is as narrow as a standard chainwheel.

Outer is expanded at 200°C and then fitted to inner, creating a permanent bond for the life of the sprocket.
