NIS running binding system. Ski bindings NNN and SNS: which ones to choose? Installing the nis platform mount

In 2005, Rottefella, together with global ski manufacturers Rossignol and Madhus, released an innovative system designed for NIS (or Nordic Integrated System) bindings. A special platform is mounted in the ski structure at the factory. That is why, without a platform, it is impossible to use this fastening fixation system. Currently, such skis are manufactured by Fischer, Madshus and Rossignol.

Using the NIS Platform

The mount moves along the axes of the platform installed in the structure. After reaching the desired position, fixation occurs with a characteristic click. The main part of the mount starts along the guides, starting from the toe. The heel kick starts from the heel. The fastening movement between the clamps occurs with the help of a special iron plate that comes with the kit. It also provides adjustment relative to the center of gravity with an interval of 5 mm.

Main advantages of NIS

• You do not need to independently determine the place of the center of gravity.
• No need to make holes in the ski yourself.
• Mounts are easy and quick to install and remove.
• You can use the same binding for several different sets of skis.
• Transporting skis without bindings is noticeably easier.
• The presence of additional adjustment gives great advantages when the weather changes.

NIS 5. A platform that is installed on racing skis (Race). Contains 5 mounting adjustment ranges with a radius of 2 cm.
NIS 3. Platform used on training (Sport) and pleasure (Touring) skis. It has 3 adjustment ranges.
NIS 1. Platform for recreational and touring skis. Has 1 position for fixing.
NIS 1 junior. Platform for use on youth skis. Contains a single item for shoes with small sizes.

The NIS platform gives the skier an edge when the weather changes. In case you are going to ride on a hard track, then experts recommend moving the mount forward. After such an action, the stiffness of the ski will be more involved.
After falling fresh snow cover, you need to move the mount back. This move will reduce the pressure on the toe of the ski. However, if the snow is loose, it will be better to set the middle position - to get an even distribution of weight.
Proper binding setup for the classic is of paramount importance for riding comfort. Depending on the position, you will be able to adjust the deflection distance with a constant weight of the rider. If you place the mount in front, then the stiffness of the ski will increase; if you take it back, you can achieve a decrease in "recoil".

With the release of the novelty, the Turnamic sole appeared, but the familiar Xcelerator is also compatible with the new bindings. There are no qualitative differences, the same sole in a different design.

The Turnamic Race, Control and Tour bindings are available with the automatic Step-in mechanism. Race Pro is fully manual only. Externally, the Step-in mechanism is indicated by arrows in the area of ​​​​the boot bracket.

If you turn the fasteners over, then you can see a spring in the mechanism - it is responsible for automatic operation.

Previously, the step-in mechanism was only on amateur mounts, they were not put on racing mounts. We have already talked about the disadvantages of automatic fasteners in the article. Tournamics do not have this drawback, they are unfastened without problems by a rotary mechanism, and not by a button. The solution is very convenient, in our opinion. Mounts are heavier by a couple of tens of grams, what will they affect? It is unlikely that they will worsen the result, but the automatic fastening is very convenient.

Features of Turnamic:

Swivel boot release mechanism

Fischer turnamic swivel mechanism

According to the manufacturer, such a system makes it easy to open and close the mechanism even with gloves. To be honest, there were no particular difficulties with the old mounts.

Fixing the binding on the ski at one point

Fixation occurs with the help of two metal pins. This is done in order not to affect the stiffness and operation of the skis. There is an opinion that skis become stiffer after installing bindings. Turnamik developers made a fix at one point. When the skis “work”, the mount moves a little on the guides, without changing the elasticity of the ski. For more information about this effect, see the video at the end of this article.

How much better is this design? In our opinion, the NIS system also did not prevent the ski from working correctly.

Adjustment without additional tools

Mounts are adjustable without a special key, unlike Rottefella. But the latest products from Rottefella are also adjustable with a flick of the wrist. The developers of Turnamic present keyless adjustment as an advantage, in fact they only changed the shape, they submitted the same mechanism in a different wrapper.

How to install NIS mounts on IFP?

Trying to put the Rottefella NIS on IFP rails will get you nowhere. The platforms are completely different. The NIS rails are a bit wider, so the mounts just won't physically go in, let alone the latches.

There are two options so far:

• remove (grind off, cut down, etc.) from the IFP ski and fasten the NIS with screws
• wait for the appearance of some kind of adapter (according to rumors, such an adapter should be released by the season 18/19)

On the other hand, usually new skis are bought with their bindings. And there are no problems with the compatibility of the boots, so you should not come up with various tricks. Moreover, IFPs are comparable in price to NIS mounts.

How to install SNS on IFP platform (Turnamic)?

The SNS system can simply be drilled. Yes, yes, as they drilled onto the NIS platform. Drills with screws will not create any platform barriers!

The only inconvenient moment is the gap between the front of the platform and the heel. The middle screw Pilot falls just on this empty spot and is in limbo. We put a washer there (the clearance is visible in the photo below). It is better to apply a strip of plastic there so that snow does not clog. In general, there is scope for imagination, but you can still put the pilots.

There was interesting news from Salomon. The SNS-IFP plate adapter has been released. The plate is placed on top of the IFP platform, and any fasteners are installed on the plate. The advantage of the plate is that it makes the platform for mounting the fasteners even without gaps.

Turnamic mounts for NIS platform

Not too advertised, Fischer released Turnamic mounts, which are installed on the good old NIS platform. Why they did this, we do not quite understand. Turnamiki do not provide any advantages, except that the attachment mechanism will seem to someone more convenient. Now let's show what turnmics on nis are.

Outwardly, they are not much different from Turnamic on IFP. Main differences:

• detachable heel
• nis latch at the back of the mount
• latch through the adapter in the front

The front part is attached in the same way as the turnamik on the IFP, only through a special adapter (pictured below).

Do not try to find this adapter separately. Turnamic ifp and turnamic nis are completely different mounts. Guides IFP platforms are slightly narrower than NIS. Mounts made for IFP and you will find an adapter for them, they simply will not physically fit on the NIS. So don't waste your time and energy on this. Put NIS mounts on the NIS platform, turnamic on the IFP and you will be happy.

Turnamic mounts marked nis are very easy to install: a special adapter is installed on the NIS, and then everything is the same as on the Xcellerator.

Interchangeable flexors on Turnamic

Replacement flexors will be on sale, but all of the same stiffness. There will be no division into Soft, Medium and Hard yet. There are only 2 stiffnesses: skate and classic. It is planned to release flexors of different hardness for the next season (18/19).

Which boots fit Turnamic bindings?

With the new system completely compatible with all boots with NNN soles. Xcellerator, Turnamic, Prolink and inexpensive NNN soles. For example, Tisa or Spine boots fit into new bindings without any problems.

Screwed IFP platform

For Salomon and Atomic skis that are pre-drilled from the factory, there are screwed IFP platforms.

Turnamic screw fixings

There is an option for screws. In general, everything is the same, only they are attached without the IFP platform. Designed for roller skates, but if you wish, you can also screw it onto skis 🙂 But again, screwing is not so simple - instead of the usual screws for a Phillips screwdriver, they put star screws.

In 2005 the firm Rottefella in cooperation with ski manufacturers Madshus And Rossignol developed a fundamentally new system for fixing the mount on the ski for racing skis ( NIS). The NIS board is mounted on the ski during the manufacturing process and uses specially designed NNN R4 NIS system mounts.

The NIS system involves the use of skis specially designed for it and having a NIS plate. To date, skis with the NIS system are produced by companies Madshus And Rossignol, Fischer.

Using the NIS system.

The mount is started according to the leading NIS-boards and is fixed "on a click". The main part of the mount starts up along the guides from the toe of the ski, and the thrust bearing from the side of the heel of the ski. Moving the mount along the latches is carried out using a special tool that is attached to each pair of mounts. The position of the mount relative to the center of gravity of the ski is discretely adjustable in 5mm increments.

Advantages of the NIS system:

• No need to look for the center of gravity of the ski.
• It is not required to drill holes in the ski.
• The mount is easy and quick to install and remove from the ski.
• One pair of bindings can be used with several pairs of skis.
• Skis can be transported without bindings.
• Mounting position adjustment allows you to choose the optimal position for different weather conditions.

Initially, the NIS system was used on the top models of skis in the racing series, but since the 06/07 season, several types of NIS boards have been produced that are used on skis for various purposes.

• NIS 5- boards used on skis of the racing (Race) series have 5 mounting positions with a long adjustable zone of 2 cm.
• NIS 3- boards used on skis for training (Sport) and walking skis (Touring) have 3 mounting positions.
• NIS 1- boards for tourist and recreational skis with a single fixation position.
• NIS 1 junior- boards for junior skis with 1 fixation position, for small boots.

The NIS system makes better use of the ski's weather range. For on hard trails, it is recommended to move the mount forward, while using the stiffness and weight deflection of the ski more.

With fresh snow, it is better to move the mount as far back as possible and thereby unload the toe of the ski. But if the snow is too loose, then it is better to install the mount in the middle position, which provides an even distribution of pressure on the snow.

For classic skis, the use of the NIS system is even more important - by changing the position of the binding, you change the height of the weight deflection and the stiffness of the ski for the same weight of the skier. If the mount is moved forward, the ski becomes stiffer. When the mount is moved back, closer to the heel, the ski is easier to crush and get rid of the "recoil".

The most popular winter sport is cross-country skiing. But in order for outdoor activities to bring only positive emotions, you need to take care of sports equipment. The article will focus on ski bindings. NNN and SNS are state-of-the-art fastening systems, and the debate over which one is better has been going on among professional and amateur athletes for a long time.

NNN

The Norwegian company Rottofella has developed a special system for attaching boots to skis - NNN. The originality consists in the presence of two rubber flexors that connect the boot to the binding, and two longitudinal guides that do not allow the boots to move to the sides. The toe of the boot rests against these springy cuffs, and after a push they return the leg to a horizontal position.

The NIS design used in the NNN bindings allows the binding to be mounted on a platform built into the skis. This is very convenient as the binding does not need to be screwed into the ski and can be moved to adjust the position of the boot in relation to the center of gravity. Many skiers use this feature to customize their skis for different snow conditions. This system also allows the athlete to place their binding.

SNS

The French company Salomon introduced its fastening system - SNS. The difference of this design lies in the presence of a central rubber flexor with one against which the boot rests. The special sole of the shoe allows the athlete to control the ski and ride any style.

The installation of the fastener does not provide for a special platform on skis, like the NNN binding, but original boots are required, suitable only for the SNS design. The usual SNS mount has only one brace in front of the sole of the boot, but there is also a modification of the SNS Pilot, which uses two metal axles that are fixed in two different grooves spaced 2.5 cm apart. This allows you to limit the lift of the foot into the air and thereby increase control over the skis.

System differences

In general, the differences between NNN and SNS mounts are minor and will be invisible to the average hobbyist, but there are nuances that a professional will pay attention to. For example, the SNS Pilot bindings are praised by many for the double engagement of the boots on the skis, which improves maneuverability, but at the same time, in not very cold weather, the snow gets under the second bracket and is compressed into an ice lump, preventing the boot from being properly placed on the binding. It also happens to unhook the second bracket when pushing. But in cold weather, these mounts work great.

Many pros appreciate the NNN binding because thanks to the platform on the ski and the NIS construction under the binding, the boot rises and the leg becomes longer. This increases the force of the push by lengthening the lever. At the same time, this effect reduces the stability of the skier, which is excluded in SNS bindings. What to choose: NNN or SNS binding, it is up to the skier to decide which boots and which bindings are more convenient for him to ride. This is an individual approach, and there is no definite answer.

Mounting installation

After choosing and buying a mount, you need to install it on your skis. You need to do this in the following order:

1. The center of gravity of the skis is determined. This is done as follows: the ski is placed flat on the edge of the ruler and shifted until it balances, like weights (parallel to the floor). If the mount is heavy, then you need to find the center of gravity by attaching the mount to the skis and shift until the balance line coincides with the fixing groove of the boot.
2. Hole drilling locations are marked. For this purpose, there are paper templates included with the mount. If there is no template at hand, you can mark with an awl by attaching mounts to the skis, according to the center of gravity.
3. Holes are drilled to a depth of 10 mm. A drill is pre-selected: for NNN - diameter 3.4 mm; for SNS - 3.6 mm. Drilling is done carefully, slightly pressing on the drill so as not to go through the ski. It is advisable to put a limiter on the drill. Then sawdust is blown out, and the holes are filled with glue for a more secure fixation.
4. The structure is being assembled. For this, fasteners are applied according to the holes and screwed. After that, it is required to dry the skis for 10 hours before use.

Everything is ready, now you can go for a ride. Apparently, there is nothing difficult in choosing and installing mounts.

Today I will share my impressions of the Rottefella Xcelerator Mounting Plate platform.
The platform is designed primarily to solve the problem of installing NIS standard bindings on skis and rollerskis without a pre-installed NIS plate by the manufacturer.
Rottefella has discontinued the iconic R3 bindings, which were exactly what they needed for bare skis and roller skates. And now only NIS mounts are produced.

I was interested in this platform as a person who shifts the NIS mounts forward or backward depending on the condition of the track. If the track is rough, I move the mount forward for better directional stability. If it is soft or medium hard, well prepared by a snowcat, then you can move the mount back, which will increase the speed of the skis.

So, what we have: OneWay Premio 10 skis, Xcelerator mounting plate black platform, Xcelerator Skate mounts.

I had R3 mounts, so I had to remove them and fill in the old holes.

For installation, we also need a special tool: a drill with a 3.5mm limiter, preferably special. conductor to install these platforms. If there is no conductor, you can mark it yourself. You can click the Xcelerator mount onto the platform at the middle notch and mark the axis of the boot. This mark will need to be compared with the center of gravity of our skis.

Conductor. The pink platform in the center sets the size of the boot, on the right the heel counter simply snaps into place fixedly.

Don't forget to fill the holes with glue. I use regular PVA glue. Can be any moisture resistant.

Bolts are included with the platform, they are twisted quite tightly. It is worth saying separately that in an unidentified form, the platforms are slightly curved and quite rigid. I had a fear that this was a defect and that I would have to heat it up to straighten it. It was made on purpose. At the time of installation and pulling the bolts, the platform sits tightly on the ski.
