Progress in development of ski stock leads skis

to its rise in price. The prices of stock are serious minus of skiing in fight against other sports for young replenishment. Even for initial equipment parents of the growing-up skier or the skier should spread the notable sums. Compare at least to expenses of parents of the growing-up volleyball player or athlete...

And to adult fans of skiing should endow very much to acquire the desired stock promising progress on a ski track. And many of adult skiers and parents of the growing-up skiers often acquire stock, being only guided by the “untwisted“ brands and by all “last“.

In this article the author will try to help to understand what in ski stock is important and that is less important that the reader could make a right choice upon purchase of stock to himself or the children...

we Will begin

of the Ski with

with the most important - from skis. It is considered to be that the weight deflection of a ski defines 60% of the sliding properties of skis, 20% are defined by material, a state and structure of the sliding surface of skis and only the last 20% are defined by greasing of skis. So, the most important in good couple of skis - a weight deflection.

Ridge skis have to possess a weight deflection as it is possible more evenly distributing the skier`s weight on a ski track, at the same time the ski pressure upon a ski track from a sock has to increase smoothly is a guarantee of good sliding. The ridge ski at pushing away by a leg should not be crushed completely - it brakes. There is a wish to note that the popular belief that the ski “catapults“ the skier after a push, is delusion. Any knowing school physics clear that excessively rigid ski will “catapult“ rather easier snow under a ski, than the skier. At the same time the rigid ski slides on often nonrigid Russian route much worse.

When testing skis above-written means that when you squeeze and you release couple of skis both hands in the middle (vertically located skis are clasped with a brush approximately in 3 cm to a heel behind the center of gravity), and at the same time look between skis in noskovy part, compression of forward part of a ski comes from a sock evenly, you observe that the gap between skis is closed evenly. Before getting new skis, develop at yourself “feeling of good couple“ - a ski poszhimayta which at you “roll“, feel skis of friends on whom they “rolled“ you. In many shops flekstester - devices for determination of rigidity of skis began to appear.

Typical “signs“ of not really good skis.

    of
  • a ski contracts with noticeable effort from the very beginning.
  • the Ski since the beginning contracts very easily, and then there comes “stop“, at such ski at repeated frequent compression it is possible to hear knock in forward part of a block.
  • At compression socks of skis disperse.
  • At strong compression by the owner * skis adjoin under a block.
  • At strong compression by the owner * under a block remains a gap more than 2 mm (except skis on ice).

* the Note - as a rule, the maximum force of compression of skis hands of the skier is proportional to the weight and power qualities defining a push of this skier.

Weight deflection of classical skis. In respect of the sliding qualities everything to similarly ridge skis. At the same time it is very important to pick up skis with the correct block. The block has to be sufficient length to provide coupling of a ski with snow at a push, and optimum rigidity that, on the one hand, when sliding on two skis the holding ointment would not brake about snow, on the other hand, that the skier could crush without effort a ski at a push and achieve coupling of the holding ointment with snow. Do not get to the child of rigid classical skis! It will not be able normally to be pushed, skis will slip, and it will fight off it any hunting to skiing.

On character of a block and weight deflection classical skis can be divided into three main types: on soft fine-grained dry snow, on transitional weather around zero, on plus and a rigid ski track.

of the Ski on fine-grained snow 45 - 60 cm, usually nonrigid with a long block, and elastic noskovy part. Skis on “plus“ and a rigid ski track - rigid, with a short block of 35 - 50 cm and with a smaller area of contact of the sliding ski surface with snow. Skis on transitional weather are something between two above described types.

So, we know now how “to grope“ the correct ski. The following question - how many steam to have and what. It is desirable to have at least two couples on the fad - one training and one racing. If you are able to afford only one racing couple, it is better to give preference to couple of skis on dry snow, nonrigid (at strong compression under a block there is a gap of 0,5 - 1,5 mm). The uniform elastic forward switch of a ski is important. If there is an opportunity to buy the second racing couple - buy skis more rigidly, they well will approach on races on a rigid ski track and a firn.

- two couples of racing skis are desirable for

of the Classic at least: one couple on soft fine-grained dry snow, other couple on plus and a rigid ski track, if necessary this couple will go also to transitional weather with a little corrected greasing zone. At movement by classics the chance to spoil skis is less, than at movement by the fad therefore training skis are not so important unless on a vkatyvaniye.

the Sliding ski surface. At present all producers of racing skis use the sliding surfaces from high-molecular polyethylene with various additives from very limited number of the suppliers guaranteeing high quality. The sliding surfaces with various multi-colored inclusions in the form of granules, fibers, etc. are not recommended. The sliding surfaces with additives ftororganik are recommended - at the moment serially only on the Norwegian skis, other producers put such plastic only on skis for contract racers (so-called “basic“).

of the Ski go on sale with a surface, polished an emery stone (in German “shtaynshlift“). From - for storages in a warehouse the surface is oxidized therefore the racers competing are recommended to protsiklevat and pass accurately skis a bronze brush of times 50 - 70. Sometimes from polishing by an emery stone on the sliding surface “wave“ appears. Do not buy such skis - “waves“ will stsiklit very difficult.

It is very important

that in use skis the sliding surface was not oxidized, for this purpose it is regularly necessary to parafinit skis even if inexpensive nonrigid paraffin (like Sviks of CH7).

of Size of skis. Do not buy too short skis! The fad - growth of the athlete plus 10 - 15 cm. Classics - the adult man - 205 - 210 cm, the woman - 195 - 200 cm. Teenage classical skis - growth plus 20 - 25 cm. On short classical skis there will be no place to place a zone of greasing the holding ointment, and short ridge skis slide worse and do not allow to realize full-fledged equipment of the course.

What skis to buy

? At limited finance the excellent decision is purchase of skis of releases of last years, they, as a rule, are on sale at the price below $200, and often differ from the “last“ skis slightly or only cosmetic. One more opportunity - to buy skis not of the most “top“ model, but the model following it. Around the world the main sales volume just falls on model of this class. These skis possess the same geometry, they have a same sliding surface, as well as at the “top“ model, the main difference that in a design of these skis not so expensive materials are used. For example, instead of acrylic polyfoam it is used poliuretanoly, or instead of carbon fiber fiber glass is used. Usually such models weigh on 150 - 200 gr. it is more, but cost at $80-100 less. The brand of skis does not matter, it is important that skis possessed the high sliding qualities and approached under the skier`s weight. Another thing is that among skis of certain brands good skis meet more often, among others - is more rare.

Greasing

Limit to

the range! You have no opportunity to test ten options of greasing. It is not necessary to subtilize, force sjekonomta on race!

So, on the example of the range of Sviks: One powder or a tablet (the tablet is more economical!) FC200/FC200S At most four ointments of sliding - LF4, LF6, HF7, HF8 Solid ointments - VG80, VF60, V55, V45, V40, V30, V10 soil Liniments - K110, K115, K120, K124, K130. On the above-mentioned range at competent use it is possible to speak successfully at races of level up to the Championship of Russia.

At damp snow the pure ftororganika has indisputable advantage. Use of powder is expensive, risky, and in the absence of a respirator maybe is harmful. Risky because of probability of a perezhog of skis therefore skis do not go and need scraping. The pure ftororganika in a monolith is excellent alternative to powder. Rubbing on the street under a fist can show good results on testing, but no more. The recommended ways - rubbing at the room temperature with the subsequent intensive grinding by a stopper, the pith roller even better rotating or pro-melting by not really hot iron (temperature as on LF6) through paper fiberlen (T150), enclosed under the iron. The laid paper protects a surface from a perezhog and allows to distribute evenly to a ftororganik on a ski. After processing by the pith roller of a ski are polished without pressing with very soft brush (T160), after pro-melting through paper the cooled-down skis are processed by a brush with stuffing from a horsehair (T150). At very damp weather and rough snow procedure of rubbing under a stopper can be repeated 1 - 2 time.

Invest

in knowledge and abilities! You do not stint the special literature giving you knowledge of greasing. Be engaged in preparation of skis more often, and you maintain your abilities at height!

Ski sticks
Ski sticks differ in
on the weight, rigidity and durability. The best combination is an easy, rigid and strong stick, but ski sticks with such combination of qualities are very expensive. Between the most expensive sticks and the cheapest the price can differ more than by 10 times!
do not get to your child expensive sticks “for growth“. Get sticks more modestly better, knowing that for the next season you will be able to afford purchase of new pair of correct length, and “to attach“ old sticks in the ski club - sport school. In general avoid
to buy to the child any stock “for growth“. It is the prerequisite of the fact that at your growing-up athlete everything will turn out, and occupations will bring joy. Let`s hope that over time in Russia the system of an exchange of stock as in Scandinavia will appear. Once a year, usually in the fall, clubs suit “market“ of an exchange of stock where people can sell, get or just change second-hand stock. The main volume falls on children`s stock here, children grow very quickly.
Is very important to get sticks of the correct length (especially important for classics!) . Universal rule: classics - growth of the athlete minus 30 cm, the fad - growth of the athlete minus 20 cm. Too long sticks for classics force the athlete to last at the time of statement of a stick up - forward, it becomes more difficult for athlete to make competent podsed, and the push easily breaks. Tiny support - “pads“ are good for the Olympic ski track. On the Russian routes the support of the bigger size which often are on sale in the form of spare parts are necessary.

of Boots - fastenings System of fastenings and brand of boots are not so important
as convenient, warm boots which to you on a pocket are important. Boots of different producers have a different block. Choose boots on a leg. Boots of last releases are of course not so “abruptly“, but will allow to sjekonomit means. The ridge boot differs in more rigid, in comparison with classics, on a bend in a sole. The leg in a ridge boot has to move easily in the longitudinal direction and have good support in the cross direction. Extent of necessary support in a ridge boot is defined by technical skill of the user in the fad. The racer tekhnichny, the smaller support of a boot he can manage. There are athletes of the international level preferring low boots for the fad. Boots like “komba“ is a quite good exit, but if you really want to enjoy the klasschesky course, buy special boots for classics.

Roller skis

Roller skis are a training means which on movement speed, on drawing of equipment and the spent efforts has to remind as much as possible movement on skis on snow. Therefore avoid to buy fast scooters with the easily rotating wheels. For the fad scooters with the wheels of big diameter setting soft in motion even on rough asphalt are good.

Big to you good luck on a ski track!
