The Profile Spline drive sprocket is CNC machined from 7075 Aluminum in the USA. This sprocket does not require a sprocket bolt; instead, it has a hardened CrMo steel insert that matches up to the 48 splines on the crank axle for pure, direct power transfer. This has 1/8″ tooth width for use with most freestyle/street & single speed chains. It will only work with 19mm, 48-spline 3-piece cranks.
