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.
Manufacturer's Note: This Profile Racing component was colored by anodizing. Anodizing is how we dye the metal. We make every effort to color match all anodized items, color shades and small color differences do occur. This is not a flaw or imperfection, but it is inherent to the anodizing process.
