The 1-1/4″ Light Weight Sprocket Carrier is made from high-quality aluminum and anodized. 

This sprocket is very lightweight to lower rotating inertia. 

The sprocket carrier has the standard 6 bolt 5.25 bolt circle x 4.5625 sprockets bore. Fits both our RSS #35 pitch and T5315 #40 sprockets. The clamping is made by two bolts rather than one; as seen on other models. This gives a better evenly distributed clamping force. Include 1/4-28 Hardware. Recommend use in Jr and stock kart classes.
