„My adventures with the MX89 started mostly on-piste, but quickly lead all over the mountain once the ski proved its abilities. No snow is too hard for the MX89, nor is anything too soft. It truly knows how to shine in all conditions. "
Tom Stiansen
With a new innovative sidecut, HOLLOWTECH 2.0 and a race-inspired sandwich construction, the MX89 is the ideal all-mountain, all-condition ski. This all-arounder is at home on both hard pack and in variable terrain, with maximum performance and stability.

With proven technologies inspired by racing and utilizing only the finest raw materials, we create unique skis, made in Austria, for each category. Sophisticated Sandwich-Sidewall Constructions and patented technologies create new benchmarks in performance standards.


Our patented, key technology is unique to ski manufacturing. By removing unneeded layers in the front of the ski we make the ski lighter. This results in several advantages: the ski becomes up to 30 % damper, the ski feels more stable, edge-grip is more powerful, steering is more precise and the overall weight is reduced. Beginning this year, we are equipping all skis with the larger HOLLOWTECH 2.0 — with the size of each Hollowtech adapted to individual model lines. A larger design for even better performance.


Each Kästle ski is built with the finest wood core, manufactured with precision to one-tenth of a millimeter. This allows us to control the weight, responsiveness and dampening characteristics of the ski, resulting in a high-quality, durable product. The wood type, or combination of different woods, is individually catered to each model line, based on the ski‘s intended application. We guarantee unique handling with outstanding performance.


Sandwich-Sidewall Construction

We adapt our Sandwich-Sidewall Construction from alpine racing and consider this technology a distinguishing feature of all of our models. This design gives every Kästle Ski optimal flex and torsional rigidity, creating sensitive and direct power transmission and ensuring total control, even at high speed. For the MX89 we used the classic SANDWICH-SIDEWALL construction.

Elliptical Radius

Each model is designed to have its own carving characteristics, which is based on the ski’s intended application, by adjusting the radius along the waist of the ski. The shape of the Elliptical Radius determines how quickly and aggressively the ski enters and exits a turn.


Graphite Sinter Base

Kästle uses uncompromisingly high-quality UHM Graphite Sintered Bases, these are used in racing. The result: excellent sliding and wax absorption properties in a durable, long lasting base.


We build our skis with classic camber and distinguish between Standard Camber and Low Camber: With STANDARD CAMBER, the ski center is clearly elevated and the contact points to the snow are far forward and back. The effective edge is longer and the ski initiates turns more quickly and precisely. 

Shovel and Tail

With the shovel and tail design, we can refine the aggressiveness of our skis.

The FAST GRIP SHOVEL is a short shovel in which the contact point and the widest part of the shovel are located far forward. This ensures a faster response at the beginning of the turn.

The FAST GRIP TAIL is designed with a contact point at the widest part of the tail, near the end of the ski. This results is a more aggressive and precise performance at the end of the turn.


With Rise technology, we optimize the shovel of the ski and control its float depending on the ski’s application.

CLASSIC RISE creates improved responsiveness for on-piste and all-mountain-slopes.
