SNS and NNN systems. Why only these two systems: everything is simple - they are the most common on this moment(everything else is a thing of the past - NN 75 mm mounts (for boots with three holes that may gather dust on your balconies) are already less practical and not so convenient, they do not fix the boot well relative to the plane of the ski).

I must say right away that both binding systems have many models that are designed for beginner skiers (amateurs) and for professionals. World-class athletes perform on both bindings, everyone chooses for themselves.

Let's start with the system SNS mounts. Developed by Salomon. Tourist (walking) options, as a rule, are automatic (with automatic fastening, you only need to insert the boot into the mount) and are suitable for a combined style of skating - classic or skate. Flexor (elastic band) of medium hardness. Their disadvantages are heavier and sometimes freeze at low temperatures.

The next step will be SNS PROFIL EQUIPE bindings (classic or skate). The only difference is in the flexors (rubbers). For skate style rides are tougher. Suitable for both amateurs and athletes of a higher level. These bindings will give you better control over the ski.

One level up are the SNS PILOT EQUIPE mounts (classic or skate). Pros: Better geometry, lighter weight, great ski control. Many professional skiers choose this model. Additionally, a WEDGE plate is installed between this binding and the ski, which raises the front of the boot by 5 millimeters, which, according to Salomon research, increases the repulsion phase and roll on the ski. There are two types: narrow and wide, your choice.

Salomon's top model is the SNS PILOT CARBON RC (RC2) ski bindings released in 2015. Manufacturers not only reduced the weight and retained excellent control over the ski, but also integrated a wedge plate that improves stability and roll distance when pushing off. The cost is much higher than previous models, but it's worth it.

All Salomon bindings are mounted on skis with screws.

Now I will talk about the NNN system. Developed by ROTTEFELLA. Just like SNS, amateur, recreational (for beginner skiers) options will be mounts - automatic machines, for example: step-in, costing about 1000 rubles. Mounted on skis with screws.

The next in the NNN line are ROTTEFELLA R3 bindings, which are also installed with screws, but they were discontinued in 2015, hence we conclude that the entire NNN line (not including amateur ones) comes with a screwless installation system (bindings are installed on pre-installed on skis NIS platform using a special key). Approximately in the same price category with R3 there are two models of mounts:

Xcelerator Junior and Exercise (There are skate and classic). The first is great for athletes different levels training with a foot size of no more than 42, tk. the length of the guide platform will no longer allow - it is one-piece. The second is for amateur athletes, of an average level of training, who do not strive to achieve the highest results.

The ROTTEFELLA XCELERATOR bindings (Skate and Classic) became the top step in the evolution. For athletes who are serious about sports. A light weight and practicality make them the perfection in the NNN range. In addition to the skating option, they put the XCELERATOR SKATE SPACER platform (similar to Salomon's WEDGE plate), which raises the toe of the binding, thereby improving stability and repulsion. It is also attached to the NIS platform with a key and the mounts themselves are installed on top of it.

Or you can choose the mounting option with an already built-in platform - ROTTEFELLA XCELERATOR SSR

Summarize. When choosing bindings, look at your skis, now most manufacturers are already embedding the NIS platform on skis (FISCHER, MADSHUS, ROSSIGNOL). In this case, I recommend installing the NNN system mounts, because. they are easy to remove and put on (can be used without problems in summer period roller skis). If you have skis without a plate (for example, it is not on SALOMON, ATOMIC, YOKO, JARVINEN, SKI TRAB), then Salomon mounts are perfect, or you can put amateur Rottefella step-in.

I have tried both systems over many years of training. In my opinion, the Salomon Pilot bindings have much better grip between the boot and the ski, due to two axles, and, accordingly, controllability at a height. The choice is yours. Below is a photo of skis with and without the NIS platform.

NNN in the online store is a widely demanded model of ski bindings for running by the well-known company ROTTEFELLA from Norway, which has a leading position in the market of sports goods. In our online store you can find NNN ski bindings for both lovers skiing as well as for professionals.

In the front part of the product there are stops made of rubber material, which contribute to the abutment of the toe of the boot during a sharp movement.

Depending on the style of riding, the consumer has the opportunity to choose the stiffness of the rubber. It is she who has a direct impact on the regulation of the rigidity of ski control.

NNN ski bindings have two parallel shoe guides. Boots are fastened with a bracket in the toe area. At the same time, the brace is shifted 1 cm back, practically under the fingers, which improves skating management.

This design of the bindings prevents snow from sticking to the boot when ski trip, since the risk of lateral movement of the boot is reduced to zero.

Benefits of NNN mounts

• Variety of shoes to choose from
• the possibility of acquiring fastening both manual and automatic
• a wide range of fasteners regardless of age categories
• affordable price

As a rule, when purchasing fasteners for the first time, beginners are recommended an automatic type, which is easy to operate.

NNN ski bindings in Moscow can be purchased through our online store NovaSport.ru. The price is unique, the goods - quality and originality, service - on high level. If you have any difficulties with choosing the type of fastening, the sales assistant is ready to provide qualified assistance. Delivery is carried out in a convenient way for the customer in the shortest possible time.

To get real pleasure from skiing, you should pay attention not only to the choice of skis, but also to the quality of the bindings. Bindings are a kind of drive, an important link between the legs, shod in boots, and the actual skis. If not everything, then a lot depends on the quality of this “intermediary”. What is the best ski carrier?

Selection of ski bindings

The right mount tightly covers the shoes, but at the same time it is able to quickly come unfastened in a critical situation. For example, if you suddenly fall during a sharp turn.

Another important point! Under heavy loads, the binding should respond adequately - continue to hold the foot in place, and not immediately unfasten.

Choosing the right mount starts with... selection. Having shoes suitable in size and all other characteristics in your sports equipment, you can start choosing bindings for specific shoes and available ones.

General information about skis and bindings

Skiing is an ancient invention. They first appeared about 4.5 thousand years ago in Scandinavia. And to this day, many improvements have been made.

For fasteners, this transformation is the most impressive. The banal tying of the leg with a belt passed through four holes sawn into the ski has been replaced by modern fastening systems made of plastic and metal.

Due to the wide range of ski equipment on the market and the literal translation of most foreign names into Russian, choosing a fastener for a beginner is not an easy task. The concept of "cross-country skiing" is especially broad. They can be "professional", "racing", "recreational", "universal" and so on.

It is best to choose inventory, based on speed.

• Sports equipment will be required for those who ride at a speed of 15 to 30 km / h on a good track.
• Amateur equipment is ideal for those reaching speeds of 9-15 km / h.
• Movement on the ski track no faster than 4-8 km / h will require tourist equipment.

Types of ski mounts

Mounting is carried out directly on skis or on special platforms. The latter can be installed by the manufacturer and have pre-drilled holes. In this case, the fasteners themselves will have to be bought by a certain company. Any fixing systems can be placed on platforms without holes. Holes in this case are drilled independently.

Mount consists made of two separate parts and a plate under the toe, which reduces the friction of the boot. The front part is responsible for the side release, the back provides the upward release.

The size of the front and rear coverage is the same for all models. So you can use shoes any manufacturer.

Mount adjustment skiing carried out depending on the weight of the skier. It also takes into account the experience and manner of skating. When skiing aggressively, the skis should not come loose.

1. To determine the unit of actuation of the fasteners, you need to divide the weight of a person by 10. And for beginners, subtract 1-2 units from the resulting indicator.
2. The maximum adjustment limits for ski bindings are plus or minus 3-4 units from the figure obtained at the beginning (weight minus 10).
3. Sometimes the force is indicated not in units, but in kilograms. In this case, 20-30 kilograms are subtracted from the weight.
4. To install the correct fastening unit, you can use the special tables that come with the fastening system. It is better for inexperienced skiers to resort to the help of an instructor or a seller.

Mounts are:

• Fastened by hand. Disadvantage: relatively high price.
• Semi-automatic and automatic. Flaws :
  - jamming when water enters and freezes;
  - may not open without support on a hard surface (for example, when falling into deep snow).

Fastening Features for cross-country skis are determined by the tracks on which they are used. When driving on flat or slightly rugged terrain, simplicity and low weight of the mounts are required.

Manufacturers produce 3 main types ski bindings: Roteffella (NNN system and its new version NIS), Salomon (SNS system) and c (familiar to everyone in the USSR).

1 77 mm (NN 75)- consists of three spikes mounted on a metal plate with a springy shackle.

Until recently, this type of binding was most often used among recreational skiers. He is well known to all of us from early childhood.

Advantages ski bindings NN 75:

• low price;
• the best option for teaching a child (enough for a year of use).

Flaws:

• difficult to put on and take off;
• a lot of cheap and low-quality models;
• boots for this type of binding are gradually leaving the market;
• inconvenient division into right and left fasteners.

2 Ski bindings SNS (Salomon Nordic System) designed for professional use. Both automatic and manual fastenings of this system are produced.

Advantages SNS ski bindings :

• high quality and reliability;

Flaws:

• special shoes are required - boots with a rod included in the groove of the fasteners;
• used exclusively on tracks treated with a snowcat;
• shortage of shoes for this type of fastening.

3 Ski bindings NNN (Rottefella) are produced in two types: fastened directly with screws and put on a special "sled" (NIS-mount).

Advantages ski bindings NNN :

• a wide selection of boots by price, manufacturer;
• the ability to choose the type of fasteners: automatic or manual;
• optimal combination of price and quality;
• availability of children's and youth models.

Flaws: automatic fasteners may freeze if water gets inside.

Secrets of selection and settings

• Experienced skiers are more likely to choose hand-attached systems.
• For beginners and amateurs, automatic options are more suitable, the easiest to use. Considering that speeds and elevation changes will be small, and the tracks will be more even, accidental shooting or, conversely, not detaching skis (in case of freezing water) is not as dangerous as when downhill on a difficult track for professionals.
  The dimensions of the bindings are selected according to the width of the skis (their "waist"). Usually they are specified by the ski manufacturer and directly depend on the ski stop, a special wire at the back of the binding.
• Screws with load scales (for adjusting the actuation) must be installed in accordance with the tables attached to the fastening mechanism. If in any doubt, seek professional advice. Arbitrary unfastening of skis, as well as failure of the release mechanism, can lead to serious injuries - fractures or sprains.
• For all beginner skiers, the soft binding marked "Classic" is suitable.
• The choice of ski bindings is an exciting process, and with sufficient theoretical preparation, it is also quite simple.

Skis are one of the most popular equipment for winter views sports. There is a heated debate among amateurs and professionals about the best option mounts - NNN or SNS. Which alternative is more reliable, and what is the difference between them? Differences are already visible at a superficial study of the issue.

Definition

NNN- This is a special system for attaching a boot to cross-country skis, proposed by Rottefella from Norway. Distinctive feature- the presence of two parallel flexors (stops), in which the toe of the shoe rests during the push. The binding is universal and fits all boots produced for NNN, except for children's and youth's.

Mount NNN

SNS is a system for fastening shoes to cross-country skis, created by Salomon from France. The most important design feature is the presence of a central protrusion, against which the toe of the boot rests when pushed. The presence of two brackets (one of which is in front of the toe) for fixing the shoes allows you to increase the controllability of the ski, which is more sensitive to the movements of the athlete.

SNS mount

Comparison

Thus, the question of choosing between NNN and SNS depends on the individual athlete, his requests and preferences. The technical differences between these types of fasteners are as follows. NNN has two parallel protrusions for fastening boots, SNS has one central one. This point must be taken into account when choosing boots, as they must be compatible with the fastening system.

At the same time, the NNN lock is located under the fingers, which makes the trip more manageable. The SNS has it in front of the toe and is considered a more reliable wear solution. Mounts NNN represented by 4 stiffness alternatives, while SNS only three. However, choosing the right option for professional sports it is possible only after training, since it is necessary to take into account the anatomical features of the athlete.

Findings site

1. Location and number of guides. NNN has two parallel protrusions, SNS has one central one.
2. Fastening system. The NNN retainer is located under the toes, 10 mm from the nose of the boot, for the SNS it is directly in front of the toe.
3. Controllability. NNN provides more control over the ski when skating than SNS.
4. The number of species. NNN is represented by 4 stiffness options, SNS - by 3 options.

Mounts - important element ski equipment. As a rule, the installation of bindings is done by a store, however, some skiers prefer to do it themselves. Let's find out how they do it.

Types of ski bindings

There are three types of ski bindings:

1. Rigid (welted) - Nordic Norm 75 mm.
2. Semi-rigid - straps, elastic bands and buckles.
3. Systemic:
   • SNS Salomon
   • NN Rotofella

Since the first two types are gradually falling out of use due to their total imperfection and moral old age, there is no need to talk about them. It is much more interesting to talk about system mounts.

It is worth noting that if the skier decides to install the NN 75mm, the installation instructions below will suit him.

Systems from Salomon and Rotofella

These binding systems have a different number of longitudinal components, functionality and boot stabilization indicators, and are also presented in various modifications. They are great for cross-country skiing - the most common in skiing.

• Rotofella system NNN appeared somewhat later than NN 75mm. The fastening and stabilization of the boots is carried out here, thanks to two longitudinal guides. The functionality of these mounts is not inferior to NN.
• In SNS Salomon only one hinge is used. Due to the nature of the soles of the boots, designed for such bindings, the skier can control the ski, making any move. This is the most modern version of ski bindings.

There are no significant disadvantages or advantages between these systems. They are more convenient, more practical and more modern than their predecessors, so they cost a little more.

How to install bindings on cross-country skis yourself

To install the fasteners, you will first need the following inventory:

• cross-country skis and fastenings on them;
• Paper template for marking or jig;
• Screwdriver (cross bit + drill 3.4 - 3.6 mm);
• Marker;
• PVA glue;
• Ruler;
• Awl.

Installation instructions

Installation of ski bindings takes place in several stages.

Step 1: Center of Gravity

The first step is to determine the center of gravity of the skis. To do this, the ski is installed on the edge of the ruler and moves along this surface until the skis freeze, like balanced scales, parallel to the floor.

The middle lines of balance should be marked with a marker. The marked line will coincide with the axis of the bracket attachment.

Step 2: Markup

The next step is to mark the holes on the ski platform. This action is performed using a paper template, which is usually supplied with the mounts. If it wasn’t on your hands, it doesn’t matter, you can download it from the Internet, or mark the ski with an awl, attaching the assembled mount so that the center of gravity coincides with the axis of fixation of the shoe.

At the same time, in the NNN system, the holes are located in front of the axis of the center of gravity, and in the SNS, the axis lies directly under the mount. For professional marking, a conductor is used.

Step 3: Drill holes

Before drilling, you should check the distance between the holes located on the mount with the distance between the points marked during marking.

Holes for Rottefella are drilled with a drill with a diameter of 3.4 mm, and for Salomon - 3.6 mm. The depth of the holes is 10 mm. Drilling is performed at medium speed with light pressure. To ensure reliable fixation, the finished holes are blown and then filled with glue.

Step 5: Assembly

Now that the holes are ready, you need to attach the fasteners and tighten the screws tightly. After that, the ski is left to dry (about 10-12 hours).

Now cross-country skis are ready for use. As you can see, there is nothing difficult in this. The main thing is to exercise caution and attentiveness, as well as to have all the necessary tools.
