The Key to the Active Stringers Strength is the stiff and ultra lightweight carbon I-beam through the center of the board. This prevents the board from over flexing and damaging the laminate when flexing beyond the working range. The secret to the Active Technology flex is the high memory polypropylene layer, that allows the full bi-axial carbon skins to flex and compress within the working range. The combination gives a perfect blend of maximum flex, with maximum durability.
