Hypersonic is a fast, stable ski, built with the most technically advanced materials. 2012 Hypersonics have a PR90 Triaxial Carbon core and a P190 Nano universal base. Older Hypersonics have a PMI Acrylic Core and a sintered P-Tex 4000E base impregnated with Cera-F fluorocarbon wax that resists absorption of dirt and debris. Edges are reinforced with epoxy to stay sharp in icy conditions. An aggressive, torsionally rigid ski, Hypersonic has a triaxial lifter - a center ridge built on top of the ski that effectively distributes the skier's weight and effort along the entire length of the ski.
Three flavors of Skate: R (Regular); HP (hard packed snow) and SC (soft conditions). Compared to Regular, the SC has less sidecut to give it more "float" in softer snow, while the HP has a higher carbon fiber content for extra stiffness.
Madshus Hypersonic Skate SC: Weight 1050g/190cm, Sidecut 44-43-44mm, Lengths 180-195cm/5cm
