Renthal Ultralight Road 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.
To help improve overall wear resistance of Renthal Road Chainwheels a hard anodising coating is applied which increases the hardness of the material giving better wear resistance.
