close-window open-window

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.

Weight

Designed to keep revolving un-sprung mass to an absolute minimum and power transfer at a maximum, Renthal Ultralight™ rear chainwheels are 66% lighter than steel.

CNC Machined

Each Ultralight™ Rear Chainwheel that leaves Renthal's engineering facilities in the UK is individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit.

Premium Materials

High strength specially enhanced 7075 T6 aluminium alloy is used to create the perfect rear chainwheel, that is both lightweight, durable and strong.

Mud Grooves

Ultralight™ Rear Chainwheels feature Renthal's self cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components.
