All new for the young riders in BMX racing, an ultralight 2 piece Crank set, featuring a 4 Bolt Spider Arm with a 24mm Alloy Spindle Axle thats press fit into the crank arm. The Non drive side features a dual pinch bolt design to keep the cranks tight and running smooth, all the way to the podium!

Designed for younger riders who need a strong crank set up and want to move up to a 2 piece, 24mm axle crank with a 4 bolt spider pattern but need the shorter crank arm length.
