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.

 Features:

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