The all new X IUM SKATING is a top level race ski developed for competitive athletes to expert skate skiers. Featuring the same construction and pairing process as X ium WCS World Cup Series skis, the new X ium Skating delivers a new level of performance for expert skiers not committed at the World Cup level. Skis are paired using the Rossignol Fit System RFS, which measures closing flex and camber shape, ensuring precisely matched pairs for optimum selection and fit. With the carbon removed, the X ium Skating delivers a larger sweet spot for more accessible, high performance racing. The S2 model is designed with a universal flex and camber height ideal for all snow conditions. NIS Compatible.
