Description
The Renthal TwinRing Rear Sprocket delivers the durability and lightweight performance that serious off-road riders demand. By combining a high-strength aluminum core with a steel outer ring, this sprocket outlasts standard all-aluminum alternatives by three times while remaining lighter than all-steel options. Smart engineering—including self-cleaning mud grooves and a permanent thermal bond—means less maintenance and more consistent power delivery on the trail.
