Description

The Profile spline drive sprocket is CNC machined from 7075 aluminium in the USA. It requires no sprocket bolt: a hardened chromoly steel insert matches the 48 splines on the crank axle for pure, direct power transfer.

It is available for 19mm splined axles only and is supplied with the 19mm splined steel insert. The 1/8" tooth width suits most freestyle, street and single speed chains.
