Kästle’s MSRP’s hover near the peak of the retail pricing mountain, where the air is so thin only a few brands can survive in it. The relatively new Czech ownership wants to expand the line by dropping a few experimental models down to a lower altitude, where the people, particularly less affluent younger people, can afford to acquire them.
Hence the ‘Z” in its name, a reference to Gen Z, otherwise known as young adults. The first foray in this direction was the ZX108, a non-metal, robustly rockered Big Mountain model with surprising moxie, introduced just last year. The ZX100 is its first offspring, with a retail tag of $799, a pittance for a Kästle and right in line with the rest of the market.
The low price wouldn’t be worth much if the ski couldn’t cut it, but the ZX100 is a knockout, particularly in the softer snow it’s made for. This became evident on a spring day at Mt. Rose, where the snow surface evolved from boilerplate to mush in the span of three hours. As soon as the top surface became loose enough to dislodge, the ZX100 was in its element. Without metal to dampen its response to pressure, the ZX100 feels quick and lively even though its natural sidecut radius is 18m in a 180cm and short turns aren’t really its wheelhouse.
Any ski with a Power/Finesse Balance score above 90 is doing a lot of things right. The flex is balanced and even, and the ZX100 resides comfortably on the borderline between drifting and edging as it dances close to the fall line. If you want to make a tighter turn that’s more carve than swivel, be prepared to work for it, but that’s the case for just about every ski in this genre. It somehow manages to feel lightweight and more maneuverable than most AMW models, yet it’s not particularly light; the Kastle FX 96 Ti is actually lighter, despite sporting two sheets of Titanal.
Any clear-eyed assessment of what transpires on a powder day at any popular resort would conclude that the “powder” part of the day begins around 9:00 and ends around 10:00. For the rest of the day, all accessible terrain devolves into something considerably less idyllic. The Kästle FX106 Ti is built to cope with this reality, for it wields its smear-ability like a weapon when deep snow switches from a fluffy texture to something closer to tapioca.
During the “powder hour,” any ski with approximately the FX106 Ti’s dimensions will spool out mid-radius turns with unconscious ease; once perfect conditions are in the past, the real work begins. It’s in the slop that the FX106 Ti’s stout, wood-and-Titanal construction proves its mettle, planing over afternoon porridge that would kick a lesser ski off course. With two full sheets of Titanal in its guts, the FX106 Ti isn’t one of those fat skis where the width isn’t noticeable; rather, its heft imparts confidence that in the battle against crud, its pilot is well armed.
Left to its own devices on firmer snow, the FX106 Ti likes its turns long and laid over. Not that its probable owner is likely to be a big fan of groomers, but they’re an unavoidable aspect of resort skiing, so you might as well make them fast and fun. Of course, the FX106 Ti won’t hook up at the top of the turn like a carving ski, but it’s more than solid enough so you can open up the throttle on the dash back to the lift.
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.
