SUPERSPROX Countershaft Sprocket - 13-Tooth CST-824-13-1

If you're running a countershaft sprocket that can't handle aggressive acceleration or sustained high RPM demands, you're leaving performance on the table—and risking catastrophic failure mid-race or ride. The SUPERSPROX 13-Tooth Countershaft Sprocket is engineered with the same specifications trusted by factory racing teams, delivering the durability and precision you need to extract maximum power without compromise. Built from SCM-435 carbon-free steel and finished with an ultra-hard surface layer, this sprocket reduces friction-induced power loss while the radial lightening design keeps rotational mass minimal.
