The Profile Racing Sabre Universal spline drive sprocket is CNC machined from 7075 aluminum in the USA, as with all of Profile's products. It's a unique "universal" sprocket that uses an adaptor insert to make the sprocket compatible with spline drive or bolt-on style cranks. 36t through 45t Sabre Sprockets do not have a spider bolt hole. They can ONLY be used as either 19mm or 22mm Spline Drive depending on adapter chosen. Can not be used as bolt-on sprockets.

The adapter is sold separately and is available for 19mm & 22mm axle sizes. Click here to purchase.
