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.
Felt might seem like an unusual material to use for ski building, but in fact it is ideal for the job, being strong, weather-resistant, flexible and shock-absorbing.
When pressed using zai’s special technique, the natural wool fibres in felt form a surface that can be easily re‑worked, in a similar way to wood and natural rubber. Innovation, quality and performance — pure zai.
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.
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.
Unsatisfied with existing carbon composite solutions for ski making, we developed and patented our own – zaiíra®.
An ultra-lightweight synthesis of the most modern reinforcing fibres and thermoplastic compounds, zaiíra® improves flexibility, stability and durability. Importantly, it also has far better damping qualities than regular ski carbons.
zaiíra® is key to zai's commitment to maintaining optimum damping and smoothness with minimal weight. It makes zai skis such as laisa, nezza and zai for Bentley the most balanced and durable of their time.
Available in 166, 177 and 188 sizes, this ski’s exhilarating performance has already won the approval of pro skiers, including former Olympic and World Cup racers.
scadin 166 delivers race handling across a wide speed range, from cruise to high speed slalom turns. Its generous width allows extreme carving.
