EMC F - The HEAD EMC (Energy Management Circuit) features ceramic piezo plates incorporated into the front and rear of the ski. Here, the kinetic energy is converted into electronic energy and in turn, the electronic energy is used to absorb negative vibrations. This means that the ski runs smoother and allows you to ski at a higher level all day long. Graphene - GRAPHENE is the thinnest and lightest element ever discovered by mankind. GRAPHENE is also the strongest material on the planet, stronger than diamond and 300 times stronger than steel, all in the thickness of one atom.

An adjusted size split allows a wider range of junior athletes to access the slalom ski, which combined with the Worldcup Rebels binding and plate, create a winning package. The ski’s race heritage sandwich construction includes Titanal and Graphene—renowneded for its high strength-to-weight ratio, resulting in a strong, light and balanced ski. HEAD’s EMC Front technology manages energy by reducing unwanted vibration for a smooth, stable ride down the course. Head Youth WCR e.SL Rebel Team SW RP Race Skis
