Skis come out of the mold flat, then tips are bent into place, causing a natural outward pressure. Preloaded tips absorb much of a bump’s load before it reaches the sled. While other plastic skis use rigid, bolted-on metal mounting saddles, the patented C & A all-plastic saddle is molded into the ski, allowing the most flex and reverse flex around. Simple 90° angles on a square keel and flat-bottom design floats on the snow instead of relying on engineered-in lift the way other skis do. Exclusive ball and cup ski tip loop assembly reduces rigidity and increases tip flexibility. Mounting kit must be purchased separately. High-performance Razor Ski has been designed to provide aggressive control for experienced riders and racers. Features are very similar to the ADX ski but with "V" shaped outboard keels. Total weight is 6.6 lbs. (including handle).
