Rigidity of skis Fischer skating table. All about the numbers on Fischer skis: structures, diagrams, HR, FA, SVZ. Fischer ski serial number: decoding

(XC ski, Nordic ski) - designed to move on relatively flat terrain by using the energy of the skier.

Cross-country skiing by skiing style are divided into several categories:
Skis for classic skiing, skis for skating, combined skis (Combi), tourist skis backcountry.

Cross-country skiing by skill level skier can be divided into:
Skis for beginners, skis for intermediates, skis for experts, skis for athletes

1.1. Classification of cross-country skiing by skiing style

1.1.1. Cross-country skis for skating

With the skating style of skiing, the skier resembles a skater with his movements: he pushes off the snow inside skis, transferring body weight to a sliding ski. The movement is then repeated on the other leg. Skate style skiing is ideal for well-rolled wide pistes, involves active work hands and body. Repulsion with sticks occurs in accordance with the rhythm of the footwork.

Skating skis, unlike skis for classic skiing, are shorter - the maximum length is 190-192 cm, and are rigid in twisting and in the longitudinal direction. Unlike a classic ski, a skating ski during a kick should not completely touch the snow with its middle part (the required gap is 2-3 mm), otherwise the kick will be less effective. Skis for skating can be distinguished by a blunt toe.

1.1.2. Cross-country skiing for classic skiing

AT classical style skis are located strictly parallel to each other on a specially built ski track.

Classic skis, compared to skating skis, are longer (maximum length 205-207 cm) and softer, and have a longer pointed toe. Less stiffness compared to skating is needed so that during the push the ski touches the snow with the middle part (block) and the holding ointment or notches “work”, then the ski will not slip back during the push. At the same time, classic skis should not be too soft, otherwise, while sliding, a block with a holding ointment or notches will prevent slipping and slow down the skier.

1.1.3. Combined skis (Combi)

Combined skis - skis designed for skating and classic skiing. Usually combined skis have a maximum length of no more than 200 cm. It is not advisable to produce combined skis with a length of more than 200 cm, in view of the fact that when skating, the heels of the skis will cling to each other. In their design, combined skis are closer to classic skis due to the fact that on classic skis ah, it is still possible to move by skating, but on a purely skating ah with a classic move - no, because due to the high rigidity of the block (part of the ski under the boot), the skier will not have a repulsion phase.

1.1.4. Backcountry touring cross-country skis

Skis for extreme tourism(BACKCOUNTRY) are for lovers ski trips in conditions where there is no ski slopes, nor recreational ski tracks for sports, tourist trips of various levels. They are distinguished by increased rigidity (they use the technology of a wooden type-setting wedge, sandwich, etc.), a wide, more than 59 mm, sliding surface - for off-road movement (virgin lands), in some models the ski is reinforced with a metal edging. These are relatively expensive skis that have passed a number of special tests for reliability, since the success of a hike or expedition, and sometimes the life of a person who has challenged the wild, depends on their quality.

2. Characteristics of cross-country skis

In this section, we will focus on the characteristics of cross-country skiing. To select the optimal characteristics of a cross-country ski means to provide excellent glide under specific conditions. It is generally accepted that 60% of the sliding properties of skis are determined by the load distribution along the length of the ski (diagram), deflection and stiffness of the ski, another 20% - by the material, condition and structure of the sliding surface of the skis, and only the remaining 20% ​​- ski lubrication. In order to thoroughly understand what the ski glide depends on, we advise you to familiarize yourself with the Theoretical Fundamentals of Ski Glide on Snow.

2.1. Load distribution along the length of the ski

The distribution of the load along the length of the ski (diagram) is the distribution of the weight of the skier on the snow through the ski. Plot - the most obvious characteristic of a ski, which determines the glide in different conditions. Diagrams are distinguished depending on the type of running (skating, classic, walking) and temperature conditions (cold, warm, combined).

2.1.1. Diagrams depending on the type of stroke

2.1.1.2. Diagram of skis for skating

As you can see, in skating skis, the load is distributed over the surface in a completely different way. During the point ( Bottom part figure) it falls on two powerful "bumps", while the middle part of the ski is almost not loaded during the push, when rolling ( top part figure) there is no pressure in the central part of the ski.

2.1.2. Diagrams depending on temperature conditions

Let's consider two main types of plots: COLD plot, suitable for cross-country skiing in frosty weather and soft skiing, and WARM plot, suitable for warm weather and hard skiing. The difference between COLD and WARM diagrams is in the sharpness of the pressure peaks and in the length of the part of the ski that is involved in the glide.

2.1.2.1. COLD plot

Cold diagram has increased in length, reduced in value pressure peaks under the front and rear parts skis, which evenly distributes the weight of the skier. A more uniform distribution of pressure in cold weather reduces the effect of the dry friction force, which prevails in frost, by increasing the area of ​​water friction, the resistance of which is much less than dry friction. On a soft track, the COLD plot is preferable due to the reduction of the plowing friction force.

2.1.2.2. WARM plot

WARM diagram has pressure peaks reduced in length and increased in value. This load distribution reduces the capillary attraction friction force, which creates the main resistance on a warm track, by reducing the contact area and reducing the "suction" effect. On a hard track, the WARM plot is preferable, as the control of the ski is increased by cutting the ski edge into the snow.

2.2. Rigidity of a cross-country ski

Modern sports cross-country skis have a deflection in the middle part of their design. If you place the ski on a flat surface, you will notice that the middle part of the ski "hangs" at a distance of 1-2 cm from the surface. With the application of a load from above, the ski will be pressed, and the stiffness of this "spring" is the stiffness of the ski.
The initial and middle segment of cross-country skis is performed in the same universal stiffness and varies depending on their length. The longer the ski, the stiffer they are and the better they are for tall or heavy skiers.
In the upper segment of racing skis, manufacturers divide each size into different stiffnesses, conventionally designating them as Soft, Medium, Hard, Extra Hard. Such a division is necessary for experienced skiers, as it helps to accurately select a pair according to the anthropometric characteristics of the athlete, his weight, the features of the running technique and physical data.
For various techniques skis with different stiffness in the block area are selected.
When choosing classic skis, you can use the following test:
- skis are placed on a flat surface and stand on them in such a way that the toes of the shoes are on the line of the center of gravity
- it is necessary to distribute the weight of the body evenly and ask the assistant to pass a thin sheet or probe 0.2 mm thick under the ski
If the skis are chosen correctly in terms of stiffness, then the sheet should move freely under the skis by 25-40 cm towards the toe, and in the opposite direction - to the end of the boot. If the stylus moves forward a shorter distance, select a more hard skis. If the probe moves back 3-5 cm beyond the end of the boot, then softer skis should be selected.
If you transfer the body weight to one of the skis, then the probe or sheet of paper should move freely 10-15 cm forward from the center of gravity and half the length of the foot back. After transferring body weight to the toe, the probe or paper should be firmly clamped between the floor and the ski. If the skis meet the above requirements, then they are suitable for you in terms of stiffness.
When choosing skating skis and distributing the weight of the skier on both legs, the probe should move forward from the center of gravity by 40 cm and 5-10 cm back from the heel of the boot. After transferring body weight to one of the skis, the clearance should decrease by no more than 10 cm towards the tip of the ski. The gap should not end under the heel of the boot. When repulsed, there should be a gap of 30-40 cm.

2.3. Cross-country ski base material

In the production of modern skis, a plastic sliding surface is used. First plastic skis Easily washable and poorly lubricated ABS plastic was used, which is almost completely ousted from the ski manufacturing market by ultra-high molecular weight polyethylene UHMW-PE, with the exception of the cheapest models of some manufacturers. Large modern manufacturers the sliding surface is made of synthesized ultra-high molecular weight polyethylene (High Performance Polyethylene - HPPE). This thermoplastic material is used in industrial applications where low friction and high abrasion resistance are required. The common name for the material is P-Tex. It is made by pressing crushed polyethylene particles under high pressure to form a crystal lattice with amorphous zones filled with lower density polymers or special fillers. 5-15% filler is added to the material intended for ordinary mass skis and for frost - carbon particles with a size of 20 microns to remove electrostatics, as well as graphite and fluorocarbon compounds to improve glide. Carbon black makes the base of the ski black, but also somewhat reduces its wear resistance. Gallium compounds add thermal conductivity to the plastic, the same property as boron nitride, but this additive further reduces the ability to absorb moisture. Ultramarine pigment is used in skis without carbon black to create a pattern on the base and improve glide.
Ointments can be applied to the base of any ski - for sliding and holding. By itself, HPPE does not have a porous structure and does not absorb ski wax, however, under the influence of high temperature, the ointment penetrates into amorphous zones and is retained there. From a chemical point of view, ski lubricant changes the water-repellent properties of the sliding surface by changing the forces of surface tension, and also provides its lubrication, thereby reducing the friction force. Additives included in the composition ski waxes, such as fluorine components, graphite and molybdenum, provide additional advantages to achieve a high glide quality.
Also, a rubber strip can be recessed at the base of the ski in the block area. Usually there is “zero” in the designation, such skis are designed for positive wet skiing and have a rather narrow weather range of use. The modern oil-free version of repulsion is the attachment of a skin imitation under the block, which is indicated in the name of the ski as “skin”. Also, to hold the ski under the block, a special adhesive tape can be glued or various mechanical forms of hooks are used in the design, which do not prevent slipping, but work when repulsed.

2.4. The structure of the sliding surface of cross-country skis

The factory application of the structure to the sliding surface adapts the skis to strictly defined conditions of use: air temperature, humidity, snow conditions, style of movement. It also improves gliding by reducing the area of ​​contact with snow and reducing the suction effect as a result of breaking the water film formed during sliding. The pre-applied factory structure allows you to select the racing pair best suited to the weather and track conditions on race day.

Below are the structure types of Atomic and Salomon cross country skis:
- AC 3 - universal cold -8-17 C, cut into classics and fad, works especially well in Scandinavia;
- AC 4 cold -8-15 C, universal structure, cut into a skate, especially good at high humidity;
- AC 5 very cold -8-20 C, wide range, cut into a skate, but sometimes into a classic, works especially well in Central Europe
- AM 1 medium -3-10 C, universal, cut into both skate and classic, especially good for a mixture of new and artificial snow
- AM 2 medium -1-5 C, cut into NO WAX skis and skates, sometimes into classics, under fresh falling snow and gloss, wet snow
- AM 6 medium -1-8 C, universal structure, cut into a skate, but sometimes also into NO WAX and classics, into coarse-grained snow
- AM 7 medium -4-10 C, cut into classic and skate, universal structure on dry snow, works well on classic and in colder temperatures
- AW 1 warm -4-0 C, cut into classic and NO WAX, universal for wet snow and wet snow
- AW 7 warm -2-0 C, cut into skates and classics, under coarse-grained (spring) snow, additional manual knurling / cutting can be applied from above
On skis produced without a special order, the World Cup Cold (WCC) or World Cup Warm (WCW) structure is cut according to the structure - universal structures for cold or warm, respectively. The task of these structures is to prepare the skis for the universal snow conditions of the track.

You need to choose a pair of skis that suits you in terms of height and weight, purpose, and you have difficulties or do not want to study the details, then experienced specialists of the online store site will help you with this.

The length of the skis is selected depending on the height, and their rigidity - on the weight of the skier.
The rules for selecting skis by length are different for skating and classic skis.

The classic form of ski selection: Skis for skating should be 10-15 cm longer than the height of the skier. The recommended length of skis for classic skiing is 25-30 cm more than the height of the skier. Pleasure skis are selected in the range of 15-25 cm more than their own height.

Fisher recommends choosing the length of the skis based solely on the Weight of the skier. We recommend that you determine the size of the ski according to the manufacturer's recommendations using the size charts. The rigidity of each ski of each size is strictly verified and corresponds to the indicated recommended weight.
AT racing skis, having differentiation in stiffness (stiff, medium, soft), this characteristic is determined by the stiffness index and the selection of skis should be carried out based on the manufacturer's recommendations.

Do not try to buy short professional skis, even if they are easier to ride and shove into the interior of your car. The nature of ski sliding on snow is such that the longer the ski, the more straight and better it rides.

After the selected ski length and stiffness - soft, med, stiff. Skis are selected by FA value.

HARDNESS INDEX FA, HR,

HR is the residual deflection, measured in millimeters, after the ski has been subjected to a standard weight for this size.

The stiffness index FA is the maximum load, measured in kilograms, applied 7 cm below the balance point, compressing the ski to a gap of 0.2 millimeters (ointment layer thickness).

For each weight of an athlete, depending on the qualification, technical features and the condition of the track, there is a fairly wide range of stiffness index with a spread of ten units.

This is a manufacturer's ski selection table.

For hard runs, skis with a large FA from the range are usually chosen, for soft runs, lower FAs are usually chosen. Also from the type of skis Cold PLus. For cold skis, lower FAs are usually used, for warm skis, higher FAs.

You can learn a lot more about skis than what is written in bright large letters on their surface. The ability to read information on skis will help you choose the right skis in the store and not be deceived when buying already used skis. We will tell you all about the numbers on Fischer skis in this article.

Fischer ski serial number: decoding

On the sidewall Fischer skis in the area of ​​\u200b\u200bthe heel of the mount there is a serial number that all amateur skiers want to decipher. There are even those who are looking for sacred meaning in these figures. In fact, everything is simple in the number, like in the number of any other product.

187/1450688580 031

• 187 - ski length in cm
• 14 – year of issue (2013)
• 5 - stiffness (4 - soft, 5 - medium, 6 - stiff)
• 06 - serial number of the week of issue from the beginning of the calendar year
• 88580 – ski serial number
• 031 – stiffness index (FA).

Since 2016, the number of skis is of this kind 191/1653513931 no hardness index. The sizes of the top skate models have decreased by 1 cm, and the FA index is written on a sticker with a barcode. An example in the photo is FA 80.

And this is what the “sports workshop” ski sticker looks like with more detailed information. What these indicators mean will be discussed below.

On Fischer 2019-2020 skis, the number is printed in the area of ​​the IFP platform. It seems that the place was chosen on purpose so that the number was hidden when installing the fasteners on the screws.

Fischer ski structures, diagrams and bases for weather and track density

On the toe of the ski from the side of the sliding surface, you can find two designations, for example: 28/1Q or 28/902 or A5/610. These designations contain information about the base of the base and the design of the skis.

Fischer bases (sliding surfaces)

The sliding surface markings can be found on the base on the toe of the ski. The design is marked there.

• A5- universal base for cold from t -5C and below. It is on skis marked Cold, the factory structure code is C1-1.
• 28 - universal warm base at t -10C and above. Suitable for all types of snow, suitable for skis marked Plus. Since the 17/18 season, it has become more versatile: -10 and warmer, against the old one from -2 and warmer. The factory structure code remained the same - P5-1.

Skis Speedmax, Carbonlite, RCS:

• Worldcup 28 (Plus) - 10% graphite
• Worldcup A5 (Cold) - 4.5% graphite

Skis RCR, SCS, CRS, SC:

• Worldcup pro - 7.5% graphite
• Protec - 7.5% graphite

Skis LS:

• Sintec - 3.5% graphite

Skate ski designs

• 115 (15/11) – design for well-prepared and icy trails. The support points are closer to the toe and heel of the ski. This arrangement increases the stability of the ski. It is especially relevant on an unprepared ice track and with lack of equipment. The main disadvantages: “sticking” skis and “burrowing” into loose snow.
• 610 (61Q, 1Q)– Design for a well-prepared and soft track. The support points are brought closer to the block, which makes the toe and heel of the ski softer. This design allows the ski not to “stick” and not burrow into loose snow. The main disadvantages: they “scour” on an icy track with lack of equipment.

Classic ski designs

• 902 (90/9Q2)- Design for soft and loose trails. Similar to ridge 610/1Q, i.e. Has soft toes and heels. The last is lower than on the 812 and makes it easier to hold in difficult weather conditions. The main disadvantage: due to the low location of the holding area, the ointment will come off faster.
• 90L- a variation of the design 902. It has a higher arc, i.e. the block is raised higher. It is found on skis from a special order, and since 2018 it has been used in Speedmax Twin Skin skis (but the marking is still 9Q2).
• 812 (81/8Q2)- universal classic design. The standard arrangement of the last retains the holding grease longer, but requires more momentum to push through.

Structures on Fischer skis

The most common structures are P5-1 and C1-1. They are, according to the manufacturers, the most popular at the World Cup.

Applying structure to skis is a delicate matter. To repeat the structure, there must be the same equipment, the same grinding stone, the same emulsion, etc. Real racing Fisher structures roll only in Reed. Structures P5-1 (Plus or universal warm) and C1-1 (Cold or universal cold) are applied to the skis.

Below is full list structures that are and have been used by Fischer. A similar list is circulating on the Internet, but in this list we have corrected the temperature ranges as of the 17/18 season. If you have something to add to this list, write in the comments.

Fischer structures

• P10-1 for dry snow below 0
• С1-1 all types of snow, including fresh, temperature below -5
• С3-1 for artificial snow, temperature below -5

FA, HR, SVZ indicators: what is it and how to find out through the ski barcode

This marking is not on all skis, but only on specially selected for a professional or pre-order. That is, at the “special workshop” or “sports workshop,” as our skiers like to call it. We wrote more about the existence of a special or sports workshop in the article.

If you have skis without a sticker in front of you, then these indicators can be easily recognized. Put any QR code scanner on your smartphone, launch it and read the barcode on the skis. The program will give something like 2.7 - 98.3, if such information does not come out, then try to read another barcode. For example, we got 2.7 - 98.3, that is, ski HR - 2.7, exact FA - 98.3. Do not be surprised that FA 98 or even 97 may be written on the sticker. Skis are not made in pairs, they are assembled into pairs later and such discrepancies are within the margin of error.

On the skis of the 2019-2020 season there is a sticker of this kind. It already has a QR code for reading all information about skis: barcode number, full number of skis with size, HR and FA.

After reading, you get a number of this kind, where

• 9002972387616 - barcode number
• 186/1865078755 - the number that is stamped on the skis
• 2.2-HR
• 90-FA

• HR- clearance in millimeters, which remains after pressing the ski with half the weight of the average skier. The load is applied to the ski 7 cm below the balance point. The remaining gap is HR. Simply put, this is the stiffness of the toes and heels of the ski. For example, if you take skis with the same FA, but different HR, a ski with a higher HR will be pressed more evenly, and with a smaller one, it will be easy at first, but it will be more difficult to finish. With a large HR - a large arc, a more arched ski, with a smaller HR - a smaller arc, the block is closer to the track in the rolling phase. A low last is especially important for inexperienced skiers. In classic it will make it easier to hold, and in skate it will improve stability at the box office.
• SVZ- a characteristic showing how the ski differs from the ideal ratio of HR and FA. The value is used in production to check the quality and selection of skis in pairs. When choosing a pair of skis for yourself, the indicator does not matter.
• FA(stiffness index) is the amount kilogram, which must be applied 7 cm below the balance point, to compress the ski to a gap of 0.2 mm.

Why FA and not specific weight? The FA index is a characteristic of a ski, not an athlete. Using this parameter, a specialist can choose skis for a specific athlete. The same ski can fit a 70 kg professional skier and a 90 kg amateur skier. At the same time, both will be comfortable and the skis will work as they should. It is more difficult to select with FA than by kilograms, but if you figure it out, the selection of skis will be better.

Skate ski designs

115 (15/11) - design for well-prepared and icy tracks. The support points are closer to the toe and heel of the ski. This arrangement increases the stability of the ski. It is especially relevant on an unprepared ice track and with lack of equipment. The main disadvantages: "sticking" skis and "burrowing" in loose snow.

610 (61Q, 1Q)– Design for a well-prepared and soft track. The support points are brought closer to the block, which makes the toe and heel of the ski softer. This design allows the ski not to “stick” and not burrow into loose snow. The main disadvantages: "scour" on the ice track with lack of equipment.

Classic ski designs

902 (90/9Q2)- Design for soft and loose trails. Similar to ridge 610/1Q, i.e. Has soft toes and heels. The last is lower than on the 812 and makes it easier to hold in difficult weather conditions. The main disadvantage: due to the low location of the holding area, the ointment will come off faster.

812 (81/8Q2)- universal classic design. The standard arrangement of the last retains the holding grease longer, but requires more momentum to push through.

FA, HR, SVZ indicators

This marking is not on all skis, but only on specially selected skis for a professional or pre-order.

HR- the gap in millimeters that remains after pressing the ski with half the weight of the average skier. The load is applied to the ski 7 cm below the balance point. The remaining gap is HR. Simply put, this is the stiffness of the toes and heels of the ski. For example, if you take skis with the same FA, but different HR, a ski with a higher HR will push through more evenly, and with a smaller one, it will be easy at first, but it will be more difficult to finish. With a large HR - a large arc, more arched ski, with a smaller HR - a smaller arc, the block is closer to the track in the rolling phase. A low last is especially important for inexperienced skiers. In classic it will make it easier to hold, and in skate it will improve stability at the box office.

SVZ- a characteristic showing how the ski differs from the ideal ratio of HR and FA. The value is used in production to check the quality and selection of skis in pairs. When choosing a pair of skis for yourself, the indicator does not matter. FA (stiffness index) is the number of kilograms that must be applied 7 cm below the balance point to compress the ski to a gap of 0.2 millimeters. Why FA and not specific weight?

FA index- a characteristic of a ski, not an athlete. Using this parameter, a competent specialist can choose skis for a specific athlete. The same ski can fit a 70kg professional skier and a 90kg amateur skier. At the same time, both will be comfortable and the skis will work as they should. It is more difficult to select with FA, but if you figure it out, then the selection of skis will be better.
