Adjusting Ski Bindings – How to Adjust Ski Bindings Right?

bindings.jpg

Correctly adjusted bindings play an meaningful role in skiing. It is important to secure your skiing by adjusting ski bindings correctly for your needs. If bindings are loosely adjusted, they can release while you ski, which can lead to a serious crash. If bindings are adjusted too tight, they can stay locked and won’t release even though you crash. Again, this situation can lead to injuries. Therefore it is very important to adjust bindings correctly at least few times a year. If you ski with your child, remember to do this to your child’s bindings as well.

Bindings might have differences, but basically they work like this; Front binding locks your boot from the top and sides. There are two things to be adjusted in the front binding. In some bindings height and width are adjusted by hand, while in some bindings this is done automatically. The release sensitivity is always adjusted by hand. Personnel in a ski service do this by adjusting the screw in front of the binding until the correct DIN number is reached. With rear bindings the pressure towards the front binding is adjusted by adjusting the distance between bindings. If this is done wrong, the front binding does not work. Stiffness of the rear binding is adjusted based on skier’s weight, skills and snow conditions. As soon as the right stiffness level is found, both front and rear bindings are adjusted to the same DIN level.

What do you need to know before adjusting ski bindings?

DIN stands for Deitsches Institut fur Normung, or German institute for standardization and was started as a method of measuring industrial standards in Germany. The modern DIN ratings for ski bindings assess weight, height, length of boot, ability and age and provide a very good standard for ski binding adjustment.

There are few things you need to know before you go to a ski service to get your bindings adjusted. You need to know your

  1. Body height.
  2. Body weight. Be honest, also in the store or ski service. Knowing the right weight is a must in order to get bindings adjusted.
  3. Your skiing ability (type of skier). Be honest again as you describe your skiing skills and experience, because all these have an impact when adjusting bindings.
  4. Your age.
  5. The boot sole length of your ski boots (just take the boot with you to the store).

Equipment you need in order to adjust ski bindings

Make sure you have these equipment before you start adjusting ski bindings.

  1. Your skis with bindings and your ski boots (obvious)
  2. DIN chart (you can get the right DIN chart from your ski binding manufacturer, ski shop or the Internet (here’s an example for Salomon bindings). If you can’t find, contact the local representative of your ski bindings (importing company or manufacturer).
  3. Screwdriver
  4. Tape measure
  5. Paper and pencil to make notes

How to adjust ski bindings? – General procedure

So finally we dive deep into the topic of adjusting ski bindings. Just follow the steps, but remember that you are adjusting your ski bindings on your own responsibility. If you crash due to loose bindings, you can only blame yourself. We give you general instructions for adjusting ski bindings, but because there are so many different ski bindings in the market, our instructions may not work well with each and every binding. Anyhow, the result of adjusting ski bindings depends on the person doing the actual work, no matter how good instructions he/she is given. If you feel unsure, please walk to a ski service or ski store and let a certified ski tech adjust your ski bindings.

In general this is the procedure of adjusting ski bindings.

  1. Calculate your personal data with the DIN chart. This is an easy step as long as  you have the correct DIN chart. Use your pencil and paper to document calculation steps and end result, which is the DIN number.
  2. Double check your calculations and see if they sound reasonable. In general the DIN number should be small if you were a light beginner skier. Also if you were heavier and experienced skier the number should be high.
  3. Adjust both toes and heels of the bindings to the visual indicator setting derived from the DIN chart.The large screws in the front and back of the toe and heal, respectively, are used for adjustment and the dial is easy to read and will change with the setting. Please notice that this may differ between manufacturers.
  4. Test release settings. As soon as your bindings are adjusted, it is time to test the system. If you see something wrong, such as front binding opening, the whole adjusting procedure should be repeated. Test your bindings always when you enter the slopes. A rule of thumb is that you should be able to open your front bindings just by twisting your foot to left or right. Notice that if you ski race tracks (gates), you need to adjust your bindings tighter so that they stand higher pressure.

These were the general instructions for adjusting ski bindings. Please remember that many things can go wrong when adjusting ski bindings, and that’s why ski shops and services have their certified ski technicians. If you are not familiar with ski binding technology and binding adjustment procedure, we really recommend you to let a certified ski tech to adjust your ski bindings.

How to define the right binding mounting point on skis?

Let's dive deep into binding mounting. Be prepared, this is pretty heavy shit...

    How do u ajust the wieght on ur ski so if u crash it falls off?


  2. Nick, good question. I noticed from server stats that people look for ski adjusting information. I was too lazy to write the second, and in fact the real part of this “adjusting ski bindings” article series. I’ll write the rest as soon as possible. I’ll also cover the question you asked, Nick.

    Waste of time. Should of checked to make sure that the second part of the article was there before I read this.

    Me too!!! How annoying

    I just bought some new Noridca Supercharge Blower’s(size 9) and need to know how to adjust the length setting of the bindings. My old boots were also Nordica’s (941′s – size 9). The new sole is just over 1/8 inch longer than the old sole and the new boots do fit the binding, but I’m worried about the micro adjustment. It appears the hieght is set automatically. The bindings are Marker MRR’s (final year of production). I realize the bindings are old, but they’ve hardly been used (I ski 99% on tele gear) My “alpine” gear has less than 30 days use.

    So, how do you micro adjust Marker MRR’s?


  6. I am not 100% sure about this; but 1/8 inch is only like 3-4mm.

    I did some searching and found this:

    “Q:Anyone know if these suckers are adjustable? they look like the heel can slide a little back, but it looks like adjusting them would be a pain, or they might just be like an fks heel and not move at all.”

    “A: They are similar to the FKS heel, in that there is not a lot of room to adjust them to different boots. The amount of adjustability is basically enough to set the forward pressure, but if there is more than 10mm difference from the boot soles they were mounted for, chances are you’ll need to remount.”

    “A: “They are similar to the FKS heel, in that there is not a lot of room to adjust them to different boots.
    Yep, and like the FKS they adjust via screws on the “arms”.”

    So, what I would do:

    - Try to just ski in them, 3-4mm difference probably won’t do anything
    - Try to find the said adjust screw in on the binding “arms” (MRR heelpiece)
    - Go to a shop and check the bindings – they are pretty old anyways, and a professional check about DIN reliability etc. probably isn’t a bad idea at all?
    - Go ski and have fun!

    What happened to the second part of this article?

    …In the second part of this article we will see how you can adjust ski bindings by yourself!

    Are you going to write it or not?

    Weak!


  8. Second part was never written, but now this article is updated. Sorry for letting you wait!

    This article is helpful and a good reminder for DIN setting. In the intro you say:

    “With rear bindings the pressure towards the front binding is adjusted by adjusting the distance between bindings. If this is done wrong, the front binding does not work.”

    But, I didn’t find the explanation for how to adjust the length of the binding for you boot so it has the right amount of forward pressure. Is there just a rule of thumb for this, or have I misunderstood something in your instructions?

    Thanks!


  10. Like the3 guy said in the first place..if your’e too weak to figure it out for youself ..take it to a shop
    turn the screw clockwise it goes in …turn the screw counterclockwise it comes out…you do know which way the clocks hands go..right?


  11. Steve

    Just for information,

    its Deutsches Institut für Normung, not Deitsches….
    but well, thats not the point- is it?


  12. i need to find a din chart for my bindings


  13. hello marco..
    my son’s din settings are fine for his height, weight, ski ability etc…the binding is set centered properly, but he says when he is on the ski lift and he moves his ski, the toe of the boots wiggles side to side.
    he began to adjust the screws on the sides of the toe piece (not the mounting or DIN screws) and i cannot find any information about adjusting these screws.
    can you shed some light on this adjustment?
    thank you


  14. Can binding be shinned to correct for not being totally flat on the snow? eg for being bowed legged.


  15. I have a set of Solomon skis that I bought when a sporting goods store stopped carrying skis. I don’t have the charts for the bindings but since it is the same gear that I have rented I am going to using that DIN number. I will rent the boots so I do not have them here. On the plate where the front toe is mounted there are A B C D E F, the A number is 280 and the F number is373, is this a reference for the size of boot to be used? Or do you place the toe either forward or rearward in order to make the ski react differently? These are shorter skis to be used when someone is learning, more than likely they will have womens size 7-9 shoe in them. Thanks

    Thanks man,
    Back in the day before I went telemark, we had to get our bindings set at the shop before working at the resort. Given our weight, and ability claimed, the techs almost always set them too loose for our taste. A guy had to take responsibility for himself and turn them up as the season progressed and as the guy skied harder and started losing skiis prematurely, usually in the bumps.

    Nowadays we get our kids skis at ski swaps and they ski hard and fast for their age and weight, but they are very tentative in bumps as of yet.
    I use the charts from the www. for ball park adjustment. I start sort of low in the range to be safe and intend to turn them up if the skis start to fall off prematurely. So far they have not complained of losing skiis too soon. They’ve been skiing since they were two and are 6 and 9 now so they will likely be pushing their bindings to perform any day now. Some day I expect them to tell me they want them turned up.
    For now, I feel safe enough that I am in the low end of the range from the DIN charts. When they were just learning at a VERY YOUNG AGE, with the bindings DIN set at the lowest setting, t skis would disconnect occaissionally just because the kids fell down. That made me feel safe.

    Now that I got a pair of alpine skiis and have not skiied with heels locked in in 20 years I am going to start at the low end of the DIN range again.
    I know if I tried to take my skis to a tech he would insist on selling me some new (and little short) skis.


  17. Keep up the wonderful work, I read few blog posts on this website and I conceive that your blog is really interesting and holds lots of wonderful info. apply for funding grants http://sportscurmudgeon.com/blog/2011/11/04/mythical-picks-nfl-weekend-of-11611-2/
