The new Twin Skin Speedmax 90 is the top skin ski with a race-specific design. The highly effective positioning of the offset Twin Skin skin strips allows maximum power transmission even in hard or icy conditions. The Air Core HM Carbon core ensures maximum weight reduciton paired with stability. Innovative Cold Base Bonding Technology for optimal wax absorption and grindability, as well as a liquid waxable Gliding Sidewall for reduced friction, ensures even more speed for ambitious racers. To clean the skin strips and to increase the gliding properties, we recommend applying VAUHTI PURE SKIN CLEAN & CARE. To protect the base, a thin layer of wax is applied to the skis which must be removed and brushed off before the first use.
