Against the backdrop of the other GS race skis in this genre, the Kästle RX12 GS stands out like a ballerina among lumberjacks. Some of its superior fluidity has to be attributable to its lack of a racing plate or binding interface of any kind. The skier is closer to the snow, giving the RX12 GS a living pulse when pressured, unfiltered by extra layers of elastomers and metal.
By elevating the skier on what amounts to a taller tower, a race plate takes the subtlety out of turning; once you tip the tower over, you’re committed to the ensuing high edge angle. The lower altitude of the RX12 GS makes it easier for the skier to feather the edge throughout the turn, rather than relying on the brusque, all-in style elevation encourages.
It’s this suppleness that makes the RX12 GS so versatile in terms of both turn shape and terrain adaptability, traits not usually found in a GS race ski. All of its attributes considered in toto, the RX12 GS behaves more like a luxury cruiser than a brute gate basher. It requires less energy to guide, less force to bend and a less aggro stance to engage. Yet when you put the pedal to the metal, its edges exert a velvet grip, not quite of true race invincibility, but plenty secure enough for trenching on groomers.
As Jim Schaffner succinctly summarized its strength, “versatility is the defining thought on this model,” a comment that underscores how different the RX12 GS is from, say, the Head Worldcup Rebels i.Speed Pro or Nordica Dobermann GSR. The Head and Nordica mimic FIS race models in most ways; the RX12 GS is mellower, like a true race ski that no longer needs to train or specialize at one event.
If you want a race ski, but don’t intend to race, the RX12 GS is your kind of ride. While I don’t want to begin handing out Silver Skier Selections of Non-FIS Race skis, if I were to pick one model for an ex-racer whose energy reserves aren’t as deep as they used to be, the RX12 GS would be it.
