Step up to race-proven skate performance. The cross-country Rossignol Delta Comp Skating ski is designed for athletes and expert skiers looking for a responsive training or racing ski. It features the same lively World Cup-proven core as our X-ium line but with a large, accessible sweet spot that opens it up to a broader range of skiers. The ski is compatible with the Turnamic® binding system for the most natural ski flex and snow feel.
