How to distinguish the nnn mount from sns. How to choose ski boots and bindings
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 bindings (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.
I'll start with the SNS mounting system. 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 riding - 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 mounts PROFIL EQUIPE (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. Not only have the manufacturers reduced the weight and retained great control over the ski, they have also incorporated a wedge plate that improves roll stability and kick-off range. 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 with 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 ones are perfect for athletes of different levels of training with a foot size of no more than 42, because. 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. Their light weight and practicality make them the pinnacle of the NNN range. In addition to the skating version, 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 the summer on roller skis). If you have skis without a plate (for example, it is not on SALOMON, ATOMIC, YOKO, JARVINEN, SKI TRAB), then Salomon bindings 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.
Good bindings are an essential piece of equipment for every cross-country skier. It is they that help to clearly transfer the efforts of the athlete to the ski track, set the direction of sliding, significantly affect the speed, comfort and safety of the walk.
There are 4 types on the market today, each of which has its own advantages and features, requires the purchase of special boots or even ski models. Therefore, the choice of equipment is recommended to start with the choice of mounts.
Mounts NN 75 (Nordic Norm 75 mm)
The simplest and known to many from the very early childhood the type of cross-country ski bindings is called NN 75. This is an obsolete welt system with a locking device, when the toe is rigidly attached to the ski by rods using a metal bracket. A rubber or plastic heel is installed under the heel of the boot, but the foot is not fixed in any way at the back. Such mounts do not provide sufficient transverse and longitudinal rigidity and make skating almost impossible. Perhaps the main advantage of NN 75 mounts is their low price. Among the shortcomings, one can single out the difficulty of control on the descents and poor fixation of the foot.Ski bindings SNS (Salomon Nordic System)
Creation of convenient and modern system cross-country bindings SNS skis we owe to the French company Salomon. It involves placing the boot on one rather wide longitudinal guide. In the front part there are special rubber stops that the toe rests against when pushing. The stiffness of the rubber bands is easily adjustable, which allows you to choose the desired level of ski control.SNS mounts are divided into 2 types depending on their purpose:
SNS profile. These are universal models for skating, combined and classic skating styles. In their manufacture, flexers (elastic bands) of different hardness are used;
SNS Pilot. Designed exclusively for skating. Structurally, such mounts are distinguished by the presence of a second axis and the use of a spring instead of a rubber flexor.
Ski bindings NNN (New Nordic Norm)
NNN-type mounts were developed by the Norwegian company Rotefella. There are also special rubber stops in the front part, where the toe rests when pushed. The level of rigidity is adjusted by selecting the appropriate rubber bands in accordance with the style of riding. NNN bindings differ from SNS systems by the presence of two parallel longitudinal guides (instead of one for SNS), due to which optimal stabilization of the boot sole is achieved.In addition, there are differences in the principle of fastening the boot. Type NNN has a bracket slightly shifted back (by 10 mm). As a result, the fasteners are almost under the fingers, and the control of the ski during skating is improved.
Depending on personal needs and style of riding, the athlete can choose the appropriate elastic band for hardness. For convenience when buying gum have different colors. For classic move black (standard) or red (soft) options are recommended, and for skating - green (soft style) or white (strong).
In general, according to the main indicators and consumer qualities, NNN type mounts are in no way inferior to SNS, they are distinguished by the same comfort, controllability and reliability.
Ski bindings NIS (Nordic Integrated System)
This is the latest cross-country ski binding developed in 2005 by Rotefella, Rossignol, Madshus and Alpina based on the NNN type. The system allows easy installation on cross-country skiing fastening without the use of screws. However, on the skis themselves, the NIS platforms must be attached at the factory.The main advantages of NIS fasteners are ease of installation, as well as the possibility of their longitudinal shift. The NIS system is fully compatible with standards, NNN boots.
Each of the listed types of bindings requires the purchase of appropriate boots. Bindings and boots of different systems (for example, SNS bindings and NNN boots) are not compatible with each other.
NNN is a ski boot attachment system. This type of fastening is offered by Rottefella. The mount is considered universal and will fit any boots, with the exception of boots for children and teenagers.
A distinctive feature are two parallel stops. The mount has four stiffness options and two notches. Boots with this binding are better suited for skating due to the fact that the brace is moved back.
SNS is a profile type of fastening created by the French company Salomon. It has three stiffness options, one notch on the boot and a brace at the edge.
The main differences between NNN and SNS are:
- Fasteners. At NNN, it is located under the fingers. This improves controllability. And at SNS - in front of the toe.
- Guide points. NNN has two parallel protrusions, and SNS has one central one.
- Control. The NNN binding has the best steering control, especially when skating, which cannot be said about the SNS.
- Number of stiffness options.
Types and models
By riding style
- High boots are used for skating. They tightly fix the foot to avoid injury while riding. It is important to choose the correct size when choosing boots for skating to avoid injury.
- Low boots provide comfort while riding in classic style. They have soft uppers and soles.
- Universal or combined - suitable for both the first and second riding styles and have an average length.
By appointment
- Professional - withstand heavy loads and last a very long time.
- Hiking boots are made in such a way that it is convenient not only to ride in them, but also to walk. They are made of a combination of leather and synthetics, withstand heavy loads and do not let moisture through.
- Amateur models - have a bright design and do not have fundamental requirements and are designed for walking.
- Children's - should be easy to put on and take off, be comfortable and keep warm. Some manufacturers include an extra insole when selling children's ski boots so that the size can be adjusted and the boots last longer.
Brands
There are hundreds of brands that manufacture ski boots. How not to get confused by the names? And which brand should you choose?
Salomon. All the same French company that produces SNS mounts. Not just big, but a huge choice for any level of training. The constant improvement of boots is the release of a new model.
Lange. One of the best manufacturers. No wonder their slogan is No1 in the world market. The top models of this brand are designed by Ferrari designers.
Main feature Italian brand Tecnica is a sleeve gate. It is designed not only for top models, but also for models of other, lower levels. Another difference is the minimum vibration from the skis, this allows the leg not to get tired during long skiing. Boots of this company perfectly keep warm even at low temperatures.
Rossignol. Perhaps one of the first firms that paid attention to the design of women's skis. The brand cares about the marketability of the product, so it uses various marketing ploys, such as skis for "fatal women".
nordica. The largest manufacturer. More than 700,000 pairs of shoes are produced annually. And in the middle of the last century, the Kastle ski factory was purchased by the brand.
Fischer produces boots of its own concept. The products of this brand are considered relatively inexpensive and very popular among young skiers.
Material
When choosing ski boots, an important role is played by the material from which they are made. Leather, tarpaulin, synthetics - it all depends on personal comfort. But you need to understand that the denser and stiffer the material, the more difficult it will be to remove the shoes after use. For some hard models, you need 20 minutes of being warm.
Another disadvantage of hard rubber is that the holes made for the fasteners are pulled out very quickly. Although the price of such models is much lower than the rest. But we all remember the saying: "The miser pays twice."
Artificial leather. The most common material in the manufacture of ski boots. In good manufacturers, boots made of synthetic materials and artificial leather do not crack in the cold and last a very long time. Such models have high-quality heaters. There are, of course, boots made of genuine leather, but there are very few of them and they are purchased only by those to whom this moment is fundamental. The indisputable advantage of synthetic and artificial materials, of course, is the preservation of shape. What can not be said about boots made of natural materials.
Binding systems transmit power, determine the direction of the skis in any style of travel. Therefore, quality fastening is as important as good equipment and Sports Equipment. Therefore, before buying, it is recommended to study the mounts for ski NNN and SNS, the differences of which can ensure safety, reduce the risk of injury.
Important! The choice depends more on the preferences and needs of the person. You can finally decide for yourself which option is better only after several years of training, based on different indicators, individual anatomical features.
What is and how NNN differs from SNS
Types and models
Both systems exist in the form of various models, both for beginners and for professional athletes. Therefore, when choosing, it is recommended to rely on specific indicators. Models differ in platform height, rigidity of flexors. NNN has 4 levels of rigidity, SNS - 3 levels.
SNS can be divided into Profil and Pilot models. The Profil system is designed for all types of travel, including mixed travel. They are marked with the appropriate marks - "Classic", "Combi" and "Skate". They differ in the level of rigidity of flexors.
The Pilot binding is designed for skating. The structure of the device is the main difference. It has a double mounting axis, and instead of the usual rubber flexor, a spring is attached. It is acceptable to use Pilot boots with Profil bindings, but Profil boots cannot be used with Pilot bindings.
If we compare SNS PROFIL EQUIPE and SNS PILOT EQUIPE, then the second model has better geometry and mechanics, it is lighter, provides more precise ski control. Also on this model, repulsion is more powerful, rolling is better.
The SNS PILOT CARBON RC and RC2 systems have been upgraded to reduce weight and improve steering control as well as stability.
Tourist subtypes of the system usually fasten automatically. They are used for different styles skating, as they are universal. Such models have a flexor of medium rigidity. The main disadvantages are that the system is heavy and freezes at very low temperatures.
NNN is divided into models suitable for different styles of running, including mixed ones. They also differ in different rigidity of flexors. At the same time, an additional flexor was installed in the high-level R3 Skate and R4 Skate, specialized in skating. But it can be removed, adjusted, as a result of such changes, the fastener becomes universal. HHH also has self-closing touring models.
The Xcelerator Junior, which comes in classic skating styles, is suitable for athletes and beginners alike. Exercise is a simple model used by basic to intermediate skiers.
The XCELERATOR is a state-of-the-art device, also available in "Skate" and "Classic" versions, used by professionals. The model is lightweight and comfortable. There are also modifications for the skating version - a specialized XCELERATOR SKATE SPACER platform is installed, which raises the toe. Thus stability and repulsion are increased.
Important! The New Nordic Norm boots fit almost all NNN systems except the backcountry model.
By riding style
As mentioned above, the style of riding does not depend on the type of fastener, but on the specific model. Moreover, many of them are universal, therefore they are used for different styles of skiing. They depend on the rigidity of flexors on a particular device. However, HHH systems help to better control skis when skating.
Brands
There are brands that make boots adapted to these systems. Ski boots for SNS are produced directly by Salomon, as well as Adidas, Fischer, Alfa. Brands producing boots for the HHH system are Rossignol, Alpina, Atomic and Karhu.
Material
Mounts are made of modern materials, however, an important difference lies still not in them, but in various details. Namely, in the presence of brackets, flexors and lower fasteners. For example, flexors are made of rubber, or a spring is used instead.
For both systems I use high-quality plastic, rubber, metal parts.
Conclusion
Despite the points by which NNN and SNS can be distinguished, they are equally popular and are used almost equally in sports. Although HHH systems with automatic fastening. As the improvement progresses, the desires and abilities of a person are evaluated, based on which, he chooses the fastening system on his own.
To date, there are 2 popular types of mounts: SNS and NNN. The difference between SNS and NNN is the number of protrusions for fixing the boot. SNS has one central, and NNN has 2 small ones at the edges.
Available skating Valso and TISA mounts type NNN.
The first thing we do when installing bindings is to find the center of gravity of each ski. I did it with a corner.
Skis must balance. We draw a center of gravity line on each ski.
We press the edges of the skis to a flat surface. 
And we draw an average line between the centers of gravity on each ski.
I do this so that the mounts are symmetrical. This line should be at the junction of the ski boot and binding.
We attach the mount focusing on the line.
We put dots in the holes for the screws. We measure their symmetry relative to the edges.
Drill holes with a small drill. The drill diameter must be smaller than the bolt diameter.
Pour glue into the holes made.
We attach the mount.
We tighten the bolts.
Here's what happened.
According to the size of the boot, you need to install heels. The thrust bearing in this mount has 2 fixation points, since it is not a continuation of the mount, but goes as a separate element. In other mounts, the thrust bearing extends from the mount to the desired length and is screwed onto one self-tapping screw.
Measure and drill 2 holes. We insert the thrust pin into one, and tighten the self-tapping screw into the second. Thus it is fixed.
