Fully induction heat-treated and hand-finished, this sprocket features a hardened surface structure that reduces rolling friction and prevents early tooth hook wear, outlasting standard mild steel components by two to three times. Dropping down to a 12-tooth front size is the ultimate way to maximize low-speed acceleration, corner pull, and climbing power on tight tracks or rugged trails.\u003cspan\u003e [\u003ca
