Description
If you're pushing your bike hard on track or trail, sprocket wear translates directly to power loss and premature chain failure. The SUPERSPROX Countershaft Sprocket eliminates that risk with factory-grade materials and precision engineering that professional racing teams trust. You'll feel the difference in reduced friction, smoother power delivery, and significantly longer component life.
Built from SCM-435 carbon-free steel and impregnated to resist breaking, this 13-tooth sprocket is engineered for both street and off-road abuse. The ultra-hard surface layer minimizes chain drag, while radial lightening holes reduce rotating mass without compromising strength. Grooved teeth shed dirt and debris instantly—the same design choice that factory teams made long before aftermarket parts caught on.
