The Pulse® SLS sprocket is made of 7075 aluminum alloy with heat treatment (T6). It is fully CNC machined.
This sprocket fits perfectly on all Shimano standard freewheel bodies, the machining allows optimized centering of the sprocket to reduce the risk of hard spots in the chain. The sprocket has a 8mm thick span at the splines to optimize power transfer and reduce deterioration of your freewheel body if it is made of aluminum.
