By reducing the amount of materials in low-stress zones, we’re able to reduce the swingweight of your snowboard, while also reducing chatter in the tip and tail - all without sacrificing strength. Built using the hardest and fastest Sintered base material on the market from Crown, the Wax-Infused Sintered 4001 holds wax longer than other Sintered bases for a smoother glide, longer. The smooth-flexing cousin to our A1 core, our NEW S1 Core is designed to be damp underfoot and stronger than hell. Constructed from Bamboo, Aspen, and Paulownia, the S1 Core let’s each wood do what it’s best for. Tip-to-tail Bamboo stringers add snap, durability, and damping underfoot and are balanced out by lightweight Paulownia in the midbody, tip, and tail help to reduce swingweight. Underfoot, Aspen and Bamboo are placed at 30 ° angles to increase strength, supercharge the edge-to-edge response, and increase the pressure distribution along the edge. An integrated carbon weave that runs the entire length of the board, intersecting at 90º angles in the tip and tail for adding torsional rigidity and responsiveness and a more relaxed angle between the inserts for handling and maneuverability. An American made Aerospace grade precure fiberglass core insert used to provide unmatched structural performance at reduced weight. SpaceGlassTM inserts increase edge hold along contact points, reduce chatter, and provide unequaled durability. Pre-cambered Carbon Power ForkTM additives are strategically shaped to offer greater response and energy return by increasing the width toward the tail - allowing for more material to be engaged, and more energy to be created the harder the tail is flexed. Add snap to ollies, increase edge pressure, and give energy in and out of turns. This top sheet material sheds unwanted snow build-up, keeping your snowboard light and nimble. 2x4 Insert packs allow for secure binding mounting while optimizing stance-width options.
