RX10 Junior Classic Skin

All of our cross-country skis feature a carbon-reinforced CAP construction where the surface layer runs over the sides, effectively protecting the core.
Each Kästle nordic ski is thus impeccably designed for its designated application.

Nowhere is survival harder than in nature – and the solutions we apply here are fittingly sophisticated. Bees, with their hexagonal-shaped honeycomb, have developed a very stable structure that results in maximum strength for minimal material input.
That is why the core of a Kästle ski is made using the honeycomb principle and natural materials. It reduces weight to a minimum and simultaneously increases stability. It also maintains good flex and results in explosive rebound underfoot.

UL WOOD
The honeycomb structure is encased in a torsion box made of ultra-lightweight paulownia wood, which we call UL WOOD. It ensures optimum torsional and flexural rigidity at minimal weight.

Professional cross-country skiing is an extreme sport – both for athletes and for their equipment. And with a wide range of temperatures and snow conditions to contend with, there are variables that are beyond our control.
We´ve developed four bases to generate the best performance in the widest range of conditions.

SKIN
A no-wax ski that does away with the need for kick wax or wax application skills and heralds the revival of classic cross-country skiing. The skin in the kick zone ensures good grip even on hardpacked, smooth snow, yet enables the ski smoother and more silent glide performance than any other fish scale cross-country ski. This is the perfect choice for easy handling in all snow conditions and in air temperatures ranging from +10° C to -30° C

We only use high-quality graphite sintered bases. This results in excellent glide performance and durability. We offer three different types of base to perfectly suit every application and condition.

WC RACE PLUS
High-performance World Cup base with outstanding wax absorption and superb glide performance. Suitable for a wide range of snow conditions.

In addition to the base material, the grinding of the base determines glide performance and must therefore be selected according to the prevailing conditions. As a general rule, the warmer it is, the coarser the structure required.

We offer four different grinding structures – two for warmer conditions and two for colder conditions. The two top-quality UW1 and CW1 grinding structures are hand finished to achieve the best glide performance. UM1 and CM1 are machine processed.

The grind is applied at a temperature just above 0 °C. Maintaining a cool environment throughout the finishing procedure, allows the small futures to be precisely ground into the high-performance base.

UW1
World Cup grinding, hand crafted for perfect results. Ideal for changeable snow conditions and wet, fine snow.

We use a specially made press to make our new cross-country skis. With over 40 adjustment points it guarantees an unprecedented level of camber tensioning and stiffness adjustment.
For cross-country skiers, aside from the length, it is the stiffness of the ski that is a deciding factor. That is why we offer a SOFT, MEDIUM and HARD version to suit the weight and height of the individual athlete. See page 42 for a detailed table on selecting the right ski.

For the RX10 Classic Skin Junior we offer the gradations MEDIUM and HARD.
