The longest lasting most durable off-road sprocket you can buy
In development for over 5 years, the new Renthal TwinRing sprocket will re-define the term durability in off-road drivetrain products. The goal when developing this product was simple: create a high quality rear sprocket that would outlast all others while keeping weight to a minimum.
The TwinRing sprocket combines a specially enhanced 7075 T6 aluminum alloy center and a high strength electroless nickel coated EN8 steel outer ring. The alloy center section keeps weight down and the steel outer ring provides durability where it is needed.
