The XComp 12 binding, from Marker, gives you the response and capabilities of a traditional race binding, but it's able to be mounted on any all-mountain ski. The XComp toe piece is designed specifically for this binding by combining the horizontal spring, that Marker designed and perfected with the Griffon, with a vertical piston that more closely resembles traditional front side bindings. The wings on the side of the binding travel with the boot to absorb any small amount of motion and transfer energy to the ski. This is a binding for intermediate to expert skiers that want unmatched performance.
