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. Color: Blue Size: 28t This is a stock photo. You will
