Renthal Ultralight™ rear chainwheels are manufactured to extremely tight tolerances from 7075 T6 aluminium alloy which is 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life. They also feature Renthal's self cleaning mud groove technology between each tooth. This prevents mud build up and helps to increase durability of the sprocket.
Renthal's combination of a high strength base material and exceptionally hardwearing surface result in significantly increased chainwheel life over other brands.
