Description
If you’re running a 520 chain setup and want a rear sprocket that can actually survive the punishment of off-road riding, the Renthal Twinring 49T is built for longevity. The hybrid aluminum-and-steel construction delivers three times the lifespan of all-aluminum alternatives while staying lighter than full-steel options—a real engineering advantage, not marketing talk. Self-cleaning mud grooves and impact-resistant design mean fewer replacements and more time riding.
