Nitro Alternator Men’s All-Mountain Snowboard. The Alternator has instantly become a team favorite because of its capable backcountry freestyle snowboard attributes – Designed for those looking to step up their game from the marked trails to the backcountry with a classic directional silhouette shape with an oversized width and loads of power under the hood -the brainchild of all-mountain maniacs Griffin Siebert and Tommy Delago. Directional Shape: The mother of all snowboard shapes. Purposeful, focused, and functional, a directionally shaped board will float in the pow, cut through the crust and provide you with a functional tail to rip it up all over the mountain. Progressive Width: A larger radius in the front, blended into a tighter one towards the tail. The Progressive Sidecut makes accelerating out of turns a breeze, while maintaining a catch-free nose area. Dual Degressive Sidecut blends a smaller radius in the center with two larger ones in the tip and tail, making it loose and playful. Nitro’s most forgiving sidecut. All-Terrain Flex: Nitro’s most versatile flex pattern, combining their signature pop with smooth response, allowing you to tear up the entire mountain. Snowboard Type : All Mountain. Range : 160 to 179. Best Use : All Mountain Snowboarding. Waist Width (mm) : 256. Sidecut Radius : 11.0 / 7.3 / 11.0m.
