Product Description

Experience the ultimate combination of light weight and exceptional longevity with the Renthal Twinring Rear Sprocket. Designed for riders who demand maximum durability without sacrificing performance, this innovative hybrid sprocket delivers extended wear life compared to standard all-aluminum sprockets while remaining much lighter than a solid steel alternative.

The inner ring utilizes high-strength Ultralight 7075-T6 aluminum to reduce unsprung mass, while the outer ring features an electro-less nickel coated steel construction built for maximum wear resistance. Bound permanently through thermal expansion, the Twinring is engineered to handle harsh off-road and adventure riding conditions.
