The Mya No. 7 is the speed machine of Head's Mya collection of women's skis. It's the women's version of the men's Supershape series, a stiff, narrow, technical carver built for expert women who love fast arcs on flat, firm groomers. It's sold only as a system, with a 12-DIN Head Mya PRD binding. Like the men's version, this detuned race carver incorporates key Head technologies, most notably the use of piezoelectronics to turn mechanical energy (the vibration of the ski at speed) into electrical energy, which is then used to stiffen fibers within the ski as needed for higher performance at higher speeds. Those special Intelligence fibers are used in the tip to progressively stiffen torsional rigidity as speeds increase, ensuring positive edge grip (though the ski remains relaxed at slower speeds, for greater forgiveness). Meanwhile, Intelligence fibers work in concert with an electronic chip in the tail to stiffen the longitudinal flex as needed for powerful turn exits and rebound across the fall line. It also employs Head's ERA 3.0 technology, in which Head pays special attention to making sure that rocker, sidecut and flex all work in perfect harmony. In the Supershape line, that means wider tips and narrower tails for 2013-14, plus the addition of a touch of tip rocker. All models are built for maximum hard-snow integrity, with full sidewalls for edge grip and classic laminate layup for integrity. Unlike the men's models, the Mya No. 7 is metal-free, for a lighter feel.
