The Renthal UltraLight rear sprocket is CNC machined from 7075 T6 aluminum. It weighs 66% less than a steel sprocket, cutting rotating mass. Computer-engineered tooth profiling maximizes power transfer to the rear wheel. Precise fitment and concentricity ensure smooth chain engagement. Self-cleaning grooves shed mud and debris for longer chain life. This 428 pitch, 49 tooth sprocket comes in Blue.
