Polveriera

A true ski with all-wheel drive 4x4

Natural materials, high-tech performance

The most eclectic kastelaar ski model, that directs 50% alpine and 50% off-piste. Thanks to the generous size of the ski that allows excellent flotation.

It confirms a technical skiing, for skiers different technical level. The 178 and 188 is chosen by the alpine guides, who goes on foot with skins and those who dare in the mountains.

  • Solid wood structure
  • -50% vibration
  • Carbon fiber and Kevlar inserted in a suitable way to improve the quality of wood
  • Fitted with any type of ski bindings
  • Piste, Off-piste, Telemark, Ski-alp

Your 4x4 kastelaar ski

The Polveriera ski is available in different solutions aesthetic and of performances: Pure, Carbon, Sport, Carbon Sport, Superligth, Extreme Superligth

Each version, both aesthetic and performance, can then be sorted Ash or Hickory wood. The Superligth versions instead are made with various wood type: Ash and Japanese Kiri wood or Hickory and Japanese Kiri wood.

The ash wood allows the creation of high quality ski, stable and performantles, from minimal vibrations that give safety even at high speeds.
The Hickory wood is probably the wood which is optimal for the construction of a ski. In the golden age of skiing, when used in ski racing in wood, all the national athletes were using skis in Hickory.
The Japanese Kiri Wood is a very light wood, very stable and impermeable that has a good balance between its lightness and the mechanical qualities

No limit

Tested in almost every gully in the Alps, track, snow conditions and situation. But not only that: also used as a snow shovel or grip for mountaineering rope.

kastelaar all one

In this model you can mount both traditional ski bindings that telemark or ski alp.
Following our company policy that favors materials and products km Zero propose traditional ski bindings Vist,
produced a few kilometers from our company and used at the World Cup.

For telemark we propose The M Medjo ski bindings

Each ski is customizable and is guaranteed two years.

Frequent Asked Questions

The character of polveriera

Skis very balanced and easy, it prefers the soft snow, but is still able to bite the ice so decided, also suitable for women. Always very stable, with minimal vibrations and safely even at high speeds.

Model very balanced and eclectic directs 50% alpine and 50% off-piste, thanks to the generous size of the ski that allows excellent buoyancy. It confirrms a technical skiing, for skiers different technical level, optimal for medium narrow radius curves. Always very stable, with minimal vibrations and safely even at high speeds.

Model eclectic directs 50% alpine and 50% off-piste, thanks to the generous size of the ski that allows excellent buoyancy. It confirrms a technical skiing, optimal for medium narrow radius. The 179 (and 189 cm) is chosen by the alpines guides, who goes on foot with skins and those who dare in the mountains.

polveriera 190 offers effortless handling at all speeds with increased tolerance for mid-turn adjustments, responding easily and precisely.

Ski Kastelaar: the best of tradition and innovation.

Kastelaar builds the best of modern wooden skis and the largest collection in the world. The increased amount of this wood in our ski is designed to drastically reduce the vibrations, the critical point of the ski, up to 50%!
Skis with this approach are high performance, they also become more stable at high speeds and give a sense of security, they are easy, precise, not tiring, ideal to preserve their body from microtrauma created by the vibrations, or for those suffering from back pain, leg or it is not in top form.

The carbon fiber, Kevlar fiber and graphene combined with proprietary epoxy resins are inserted in a suitable way to improve the quality of the wood and neutralize weaknesses that allow high-level performance based on computer simulations with sophisticated engineering programs.

Ecological and highly protective coatings ensure its durability. This allows, if necessary, at any time to easily restore the skis.

Solid Wood

Over time, the structure of wood in the ski has been replaced by metal and plastic, but since these materials do create vibrations and not reduce these there is realized the need to start to use it.
The metals are among the main causes of micro-traumas due to vibrations that create without being able to absorb them.

Today all the best ski contain wood in a percentage from 25% to 45%, but not as a structure, or use it as an aesthetic element.
In the Kastelaar ski the wood is skiing (for a percentage of 90%) and it is for this reason that we can further reduce vibration compared to all up to 50% less!
We use the wood for this and not because we are nostalgic.

The ash wood allows the creation of high quality ski, stable and performantles, from minimal vibrations that give safety even at high speeds.

The Hickory wood is probably the wood which is optimal for the construction of a ski being very stable, elastic and at the same time allows still better performances than the ash wood for precision and sensitivity. Hickory has almost disappeared in all the skiing because of its high cost. Kastelaar is now the only one in the world producing skis with hickory wood with exceptional features and incredibly forgotten. It is no coincidence that in the golden age of skiing, when used in ski racing in wood, all the national athletes were using skis in Hickory: Zeno Colo', Jean Claude Killy, Lo Lacroix, Carlo Senoner, Celina Seghi, Lo Lacroix...

Kevlar

The Kevlar fiber is an aramid fiber, high-performance, lightweight, but stronger than steel and abrasion, but above all it has the great advantage of absorbing vibrations. Here is the reason for using this material in our ski and to have in the kastelaar catalog for all models of skis the Carbon version that is realized with a larger amount of this material.

Carbon Fibre, software high-tech and tradition

To make the best of the world wooden skis need a special mix of tradition and innovation. This does not allow the use of prepreg carbon fibers, because the high temperatures used for polymerization reduce by 35% the mechanical properties of the wood.

It is necessary to work at low temperatures of the carbon fiber and with polymerization times long (about six days) to create a polymer of three dimensions, something not possible in metal skis or prepeg that use of carbon fibers, which has the mechanical characteristics very high.

In this sense we have developed specifically an epoxy resin that responds to the best to these needs. The carbon fibers unidirectional and multidirectional and are inserted along the ski with particular inclinations and in some points according to a scheme developed by a parametric CAD software in finite elements. The appearance is that of a collage.

Cutting Edge

The best quality 48HRC hardness, the same used in the competitions. Allow skiing with greater safety consuming less, in particular in artificial snow, very aggressive.

Graphene

Our visionary spirit leads us to be the first in the world to combine the graphene to the wood in a ski. All Kastelaar contain a certain percentage. This incredible material allows us to significantly increase the mechanical quality of our skis. This is not a coincidence that now our skis are also used by athletes for the World Cup competitions and in the Freeride World Tour.

Today this incredible technology is present in a traditional, yet futuristic solid wood skis!

Graphite Ski Base

Like being in a race car with maximum safety.

Best ski base whit high proportion graphite of hand-prepared by a professional ski man with long experience in the World Cup and the Olympics: ski fast, easy, accurate and stable. Quality & Tradition.

Warnings! Mounting Ski Binding - Ski edge - Tuning

Mounting binding: pierce skiing tipped by 3.5.
IMPORTANT: putting epoxy in the hole before screwing. DO NOT USE PVA GLUES.

SKI EDGE & TUNING: 88' and 0.5. The ski comes already with base waxed.
On request with a virgin base and ski edge to prepare.
Ski very sensitive to the ski edge finish, if done badly you feel, use the diamond finish.
