Features

19mm 48 spline axles only. This is a spline drive sprocket made for 19mm splined crank axles, so it will not fit 22mm or 24mm spindles.
No sprocket bolt needed. A hardened CrMo steel insert matches the 48 splines on your crank axle for direct power transfer, and the insert is supplied.
3/32 inch tooth width. Cut to suit most BMX race chains, so it drops straight into a standard race drivetrain.
36t through to 45t. Ten sizes in single tooth steps let you fine tune your gearing without jumping several teeth at a time.
CNC machined 7075, USA made. Machined from 7075 aluminium in the USA, with a 36t at 140g and the biggest 45t still only 172g.
