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 3/32″ tooth width for use with most BMX race chains. It will only work with 19mm, 48-spline 3-piece cranks. It comes with 19mm splined steel insert.
