Особенности конструкции:

Dyneema®

This plastic fibre is 60% stronger in relation to its weight than carbon fibre, and up to 15 times stronger than steel. It is also extremely light and highly resistant to abrasion. Unlike other materials it does not become brittle when exposed to low temperatures. zai is the world’s only ski manufacturer to use this highly sophisticated material.
Nano Race Base

When you ride a zai ski, you are riding the best high-speed race base in the world.

zai bases are nano-coated, pre-impregnated with wax and manufactured with a high graphite content, making them exceptionally fast and durable.

To further improve quality and performance, zai employs specialist grinding techniques to ensure a base finish that is unsurpassed. Our high-precision stone wheel grinding machines deliver a much more controlled grind than conventional belt-sanding devices.

During service, zai skis are treated with infrared heat to ensure a deeper penetration of wax, ensuring optimum performance season after season.
Stainless Steel

zai is the only ski-maker to build its skis with stainless steel upper edges. The hardened HRC 50 steel we use for this is extremely rugged and resistant to corrosion. Steel upper edges protect the ski against bumps and knocks, and can be re-worked to as-new condition during service.

We also use stainless steel in the upper surface designs of some zai skis. For this we use high-grade spring steel, the same used in the manufacture of fine Swiss watches.

Spring steel has a high yield strength, meaning it always returns to its original shape after bending. This is one of the reasons why zai skis maintain their torsion so much better than other skis.
UD Carbon Fibre

zai uses pre-impregnated UD (unidirectional) endless carbon fibres in an uncured thermoset plastic matrix. The fibres are applied to the ski by hand and in varying thicknesses, allowing tension to be precisely controlled at strategic points.

The ‘pre-pregs’ are then heat-and-pressure cured during the pressing process, resulting in an extremely strong, lightweight ski structure with excellent torsion dynamics.

Because zai ski designs are arrived at through repeated real-world testing (as opposed to being computer-generated) various thicknesses and arrangements of carbon fibres can be tried during the prototype phase. Only when exactly the right combination and placement of carbon fibres has been achieved is a ski approved for production.
Walnut Veneer

The wood surface of our testa ski is made from the finest quality French walnut veneer, sourced from sustainably forested walnut trees.

walnut provides natural damping, contributing to the smooth handling of the ski. It is also very durable, and can be re-worked to a beautiful finish.

Differences in the wood grain mean that every testa ski has its own unique character, which increases with time and wear.
