The ultra-narrow Speed is designed for unbeatable edge-grip and ripping big fast GS arcs on hard snow, and is suitable for experts who spend most of their time dicing up firm groomers. Intelligence Technology uses fibers placed in an argyle pattern in the core, in front of the binding. At faster speeds, vibrations are converted into electrical energy, and the forefront of the ski stiffens up. At slower speeds, the fibers stay limp, making the ski easier to manipulate and maintaining its ability to flex into its sidecut. This ski is only available with the Free Flex binding system in either a DIN 11 or 14.
