2023 Kastle FX96 W

The cornerstone of the FX96 W design is a poplar and beech wood core inside a fiberglass torsion box that is itself encased in a laminate, with poplar and Paulownia bookending the central core. The torsion box rides higher than the outer sections, creating a 3D top surface, which is the first weight-saver. Second is the concentration of hard woods in the center, so lighter woods can be used in the remaining 2/3 of the core. Third is using a thicker core profile in the central torsion box, which gives it more power without adding more materials. The proof of the FX96 W’s terrain proclivities is found in its double-rockered baseline. Its shallow camber pocket transitions to a long, gradual front rocker – Kästle refers to it as Progressive Rise - that starts 310cm from the tip. The tail rocker rides up a similarly slight slope 150cm from the tail. This creates a relatively short contact length that works in concert with its slalomesque sidecut (14m @ 164cm) to create a fat ski that skis skinny.
