Tapered Elliptical Progressive Sidecut allows for exceptional turn initiation and follow through. New lighter cored aluminum/carbon fiber top sheet increases high-speed control. Paulownia core reduces weight and increases flex properties for snappier turns. The low friction Race Base is made from carbon-infused sintered base material to ensure a fast ride. The Commissioner is designed for intermediate to high level riders seeking high speed all mountain terrain. He sounds pretty serious but the dude will also destroy a powder line. Wink wink.
