Sometimes hand-me-downs are a fantastic opportunity. As in the Madshus Race Speed Skin ski. Has done some of the best engineering of cross country skin skis, but for the Race Speed this model is in essence a skin ski version of what was once their World Cup classic skis. While the World Cup skis keep getting tweaked, the Race Speed design could be considered the foundation design. But as a hand-me-down design, the performance is up there, but the price came down for the rest of us. This is a fun and easy to use waxless classic ski for training, racing, or just having fun. Highly recommended to match with the Rottefella MOVE Switch binding. Camber is modified to be optimal as a skin ski Skin insert is 70% Mohair/30% Nylon, and can be replaced Profile of 43-44-44mm Move 3.0 binding plate accepts MOVE or Xcelerator bindings Ski size selected by preferred ski length/skier weight in kg
