Description
The Renthal TwinRing Rear Sprocket delivers the lightweight performance and durability demanded by serious riders who refuse to compromise on either metric. Its hybrid construction—pairing a high-strength 7075 T-6 aluminum inner ring with an electro-less nickel-coated steel outer ring—gives you the weight savings of aluminum without sacrificing the wear resistance needed for demanding track or trail conditions. Self-cleaning mud grooves and a permanent thermal bond mean this sprocket will outlast your expectations while maintaining consistent power delivery.
