Description
A worn or undersized countershaft sprocket kills acceleration and forces your chain to work harder than it should, draining power before it reaches the rear wheel. The SUPERSPROX 13-Tooth Countershaft Sprocket delivers the precision engineering and durability of factory racing parts at a price point that makes sense for serious riders and racers. Built from SCM-435 carbon-free steel with an ultra-hard surface layer, this sprocket eliminates the friction and premature wear that plague stock components, giving you faster throttle response and extended drivetrain life.
