Renthal Ultralight Rear Sprockets

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.
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.
High strength specially enhanced 7075 T6 aluminium alloy is used to create the perfect rear chainwheel, that is both lightweight, durable and strong.
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.
Renthal Ultralight chainwheels are used by more factory motocross and supercross teams than any other chainwheel in the world.
