The TMX is designed with today's technical mountain riders in mind. Compared to the previous BX model, the TMX is lighter and more finely tuned for mountain-specific performance. This unique keel design makes sidehilling a breeze and provides excellent grip on the slopes. Raised tapered tail and snow scoops further enhance the ski's sidehilling capabilities and grip in deep powder and make it easier to reverse. The nearly 2" wide keel lightens steering effort on hard-packed snow, giving you more control for less effort.
