Podium performance. A World Cup race ski for top athletes... but not only that... The Rossignol X-Ium Skating Premium+ SX ski features a full-length carbon blade and race-proven edge technologies. The result is an ultra-lightweight, balanced ski that offers maximum power transmission, glide, and fluid acceleration. The SX construction is characterized by flex and camber optimized for a wide range of snow conditions. The ski is compatible with the Turnamic® binding system to ensure the most natural ski flex and snow contact. The SX version offers: A full-length, high-modulus carbon layup maximizes the strength-to-weight ratio for optimized energy, power, and control. Total Edge Technology enhances energy activation through the use of full-length ABS sidewalls that regulate camber for maximum power transfer and acceleration. Optimized tail and tip profiles for skating provide an extremely light, balanced feel for improved fluidity, energy savings, and reduced swing weight. The Nomex® honeycomb core consists of ultralight aramid fibers in a honeycomb structure with a high strength-to-weight ratio for high-performance elite skiing. The Light+ Capless design reduces weight and balances torsional stiffness with a soft, supple flex for stability in all conditions and increased energy. The SX version of the Premium+ models is not just a World Cup version; thanks to the new pressure distribution and camber shape, this ski is extremely easy to ski and not at all demanding. The modifications to this model allow any expert-level skier to generate speed with significantly less effort. This model requires less energy from the skier than a more traditional model. Its effortless skating performance impresses not only the biggest champions but also every good skater.
