JT SPROCKETS Ultra-Light Mud-Resistant Aluminum Sprocket 822 - 520 (Manufacturer part number: JTA822.51BLK) — black aluminum sprocket for 520 transmission, designed for Cross, Enduro/Trail, and Quad practices.
This JT Sprockets sprocket is aimed at riders looking for a weight-saving part without sacrificing the mechanical integrity of their transmission. Its Ergal design reduces unsprung mass while providing the robustness expected on muddy trails or roads. The mud-resistant option helps keep the chain cleaner for more consistent performance between maintenance intervals.
