The Roxy Ally BTX is ideal for all-mountain riders that want a progressive Banana/ Magne Traction board that is smooth to ride, confidence inspiring & fun. More than capable of riding everything from park & rails, hard pack & crud through to powder, the Ally BTX features a light Alloy core & Biaxial fibreglass for a medium flexing ride that holds a mean edge. Its BTX tech means you'll float in powder with ease, catch less edges & have more control at speed, which you'll need as it has a super fast sintered TNT base. Features BTXDirectional Twin Light Alloy core TNT base Bi-Axial fibres 5 SW sidewalls Flex rating: 3 (1 = soft/10 = stiff) Glossary BTX: Banana/ Magne Traction combo. Rocker between the feet blended w/flat-to-mild camber to the contact points ? Focuses pressure between the feet for easy turns & great hold on ice, & mild pressure at the tip & tail for unreal float & catch-free freestyle. Magne Traction: Conventional skis & snowboards have two contact points. Magne-Traction boards have seven & deliver better edge hold! Control & turn initiation come from under your feet, not a foot & a half to either side of your feet, so when your two outside contact points lose grip, you've still got five more to take over! 5 SW sidewalls:UHMW (Ultra High Molecular Weight) exterior sidewalls made from soy-based elastomer are laminated to 5 internal wood layers for totally bombproof sidewalls.
