The smooth-flexing cousin to our A1 core, our 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.
