Rossignol's Delta Skating Ski is an easy gliding ski for racers who want to spend their time training instead of working overtime to pay for their new skis. They have the same Racing Cobra Sidecut and weight as Rossignol's highest-end skis but at a fraction of the price. The Racing Cobra Sidecut is designed for extremely free-flowing and stable skiing. This system enables a quicker return to the steering axis at the end of the gliding phase. The lightweight honeycomb core means longer days on the trail will be easier on your legs, and your skis will be more responsive and limber. Bottom Line: Performance at a price you can handle.
