NOTE: the hole of the 20T for the crank arm has another position than regular cranks. The 20T Ninja works ONLY with 2006 Hindenburg Flatland cranks! The Equilibrium Bikes are equipped with this feature!

This chainwheel is special made to fit to 9T Freecoaster hubs and works with 3/32” Road Racing chains. As the first company in BMX we used the Diamond Cut processing for the teeth. This is patented by a german CNC machinery and makes the teeth stronger about 30% !

Because of big interest into the Ninja CDs we added a few more teeth sizes. Now available in 20T, 25T, 27T, 28T, 30T, 33T, 36T, 37T, 38T, 39T. For this generation of Ninja chainwheels we now use 7075 T6 alloy.
