Description
If you’re running a 520 chain setup, your sprocket choice directly impacts acceleration response, chain longevity, and overall drivetrain reliability. The Renthal Twinring 49-tooth rear sprocket eliminates the traditional trade-off between weight and durability by pairing a lightweight 7075 T-6 aluminum core with a hardened steel outer ring, giving you the strength of a full-steel sprocket at a fraction of the weight. Built with self-cleaning mud grooves and reinforced fasteners, this sprocket handles side-load stress while resisting premature wear—outlasting conventional aluminum alternatives by a significant margin.
