The all-new Rossignol X-IUM CLASSIC 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 Classic 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 Classic delivers a larger sweet spot for more accessible, high-performance racing. The C2 model is a universal classic ski ideal for most snow conditions.
