The cheetah is the fastest land animal on earth; the Super 7 RD is the cheetah of the ski world. In fact, “RD” stands for race department, and these skis are a super limited run, so get ’em while they’re hot. Rossignol’s updated 7 Series “HD” integrates its Carbon Alloy Matrix to complement the paulownia wood core. The Matrix is carbon and basalt integrated into an open weave that mimics the stability and dampness of metal without loss of energy. The Super 7 “RD” is built with an even beefier core than the HD, using thicker glass found in Rossi’s World Cup race skis and providing a stiffer construction of the Carbon Alloy Matrix. This translates to a barnburner of a ski with a 30-meter turn radius and a single size of 190 centimeters.
