Made from extruded and CNC machined aluminum, this X2-SX is tough enough to handle the abuses of BMX riding without adding much weight to your set up. The SX is also equipped with triple-sealed bearings with a DU bushing for consistently smooth pedal action. Fixed front springs offer stiffer tension which eliminates unwanted unclipping and the 2-sided mechanism uses an adjustable cleat tension and release on each side. The X2-SX comes complete with exclusive X1 and X2 4D cleats, replaceable pins, and hardware.
