The GS Magnesium is Blizzards World Cup GS ski, FIS-certified and intended for racers at the highest level. As the name suggests, it gets its power from magnesium layers above and beneath the wood core. The new 2012 version boasts an oil piston underfoot designed to dampen vibration, which is integrated into a Blizzard/Marker power plate, also new this year. The plate fits Marker bindings only. Other specs are what you' d expect from a race ski: classic sandwich construction with phenol sidewalls. Sold flat.
