The mountain in the ski. This idea is incorporated in the zai spada, the worldwide only ski with a core made from stone. The granite with the carbon fibre laminate CFS is encased ®, which makes the pressure resistant stone bendable. The result is a ski with excellent turning and unparalleled quiet running and gripping properties. The spada is constantly being refined. The newest model consists of the proven CFS®-.technology and a revolutionary surface made from natural cellulose acetate, which makes every ski unique. Efficiency, robustness and simple beauty characterize the ski. Its true power becomes evident, particularly on hard slopes.
