  1. Stefan, visit this page on ISMF website for application forms and procedures – http://ismf-ski.org/www/?q=node/38&page=WhiteListAction

  2. Hello, is it difficoult to geht the apprived for a new bindings?
    How to get a ISMF approved for the bindings? (who does that make)

    thanks for your answer

    stefan

  3. Skimo Co also carries Plum race bindings that have a very similar part available to provide a higher heel riser position.
    However, by “my cross country skis” I sure hope you don’t really mean nordic skis!

  4. Eric Carter says:

    Josep – as long as the boots you use are tech-compatible, most race options will be a good choice. SKIMO.co carries the Kreuzspitze binding which can have an added heel riser attached to it.

  5. Hi! Good comparison! I’m looking for light bindings to mount in my cross country skis, specific for winter mountaniering (ice climbing, colouirs, etc.) I would like them to be durable and have comfortable heel risers – I won’t do any racing with them, it’s just not to have too much weight when carrying them in the backpack! What would be your choice?
    thanks!

  6. Very interesting! Thank you Stano!

  7. That is correct Jonathan! Will be interesting to see further development in this story.

  8. So if you can’t beat ‘em, join ‘em — or rather, rebadge them: the PG Ultimate boot and Morpho boot will be rebranded by Dynafit for next season!

  9. Peter, in my opinion they better change/simplify rules they cannot or don’t plan on enforcing. As if anyone was ever going to measure that binding-boot gap :)

    And then I see a change about outside help – seems like now it is legal to receive outside help in terms of a broken ski or a pole, you can receive it from anyone and anywhere! That is a bit strange since you can end up skiing on unsafe equipment which the rules are trying to avoid :)

  10. just got that email from dD and what I noticed is that they have changed the binding rule AGAIN. They took out the 4mm gap, requirements for ski leashes, and have used less ambiguous wording regarding lateral release.

    “ The front part must have a release system that allows the lateral exit of the boot from the rear

    part of the binding. The front release system must have a lockable and un-lockable position. ”

    My Dynafit lo-tech autos are still on the white list, and it appears they have updated the downloadable regulations to the 2013-14 version. So I’m not sure if anything really changed.

  11. I answered my own question with the purchase of the Trab Race adjustable: The whole heel piece turns to give you a flat mode. And the heel piece moves a full 3cm, for what it’s worth…

  12. Jed, from what I know I don’t think any of these have a “flat mode”. However, the heel posts are so low that if you have a flexible enough boot (nice ankle movement) you won’t need a flat mode. But I understand your concern. My problem is that for some spring touring it would be nice if I could have a higher post ;)

  13. Excellent list! Another question: This one about heel lifts, and it’s not what you’d expect. Do any of these light bindings allow one to go “flat on ski”? For mellower touring? I’m in no need of stilettos, but being able to go flat would be nice for sections…

  14. And a whole bunch of new Maruelli M2 toe and heel variations, seems all toes have “2 safety positions” = full ISMF toe releasability?
    http://www.maruelli.com/NaturalWalkingPlate/PRICE-LIST/MARUELLI-PRICELIST.pdf
    Price is now a whopping 500 euro incl VAT.
    You need the traditional 70g m1 toe for downhill races.
    m1 toe + m2 heel = 90g and the combo is ISMF approved for downhill?

    http://www.skiforum.it/forum/discussioni-generali/63441-se-vi-interessa-un-attacchino-per-le-vertical-race-da-50gr.html
    Maruelli is answering questions.
    M2 only for vertical races and seems to take a sweet minute to get in and out of, you are actually hand screwing one of the pins in to your outer boot insert?

  15. hey everybody!

    Brand spanking new Gignoux Ultimate 2 with ISMF toe releasability:
    http://www.ski-alpinisme.com/actualite/2013/fixationGignoux2013.pdf (also has Morpho 400g boot closeups)
    http://www.ski-alpinisme.com/article.php?id=4682

  16. Thanks Jonathan, will fix the price right away.
    It seemed very low at 200 Euros for such a binding. 300 is seems more realistic.

  17. Maruelli’s website is now updated for both the M2 and M1-FR … as well as for a 50% price increase in the previously published price for the M2.

  18. Updated the bindings’ notes – Plum 135 and both PHK bindings are recommended for maximum 70kg (154 lbs) users. This should be the racer’s weight including anything he or she wears/carries above the bindings (boots, backpack…), I would imagine.
    However, this does not mean other bindings have or don’t have such “restrictions”. It simply means that Plum and PHK are doing us a good services of letting us know.

  19. I’m pretty sure that the 70g split is for the Plum 135 vs 145, and is in reference to the lower effective forward release values for the Plum 135 Ti heel fork. (Lateral release values are the same for both bindings.) However, since Ti is stronger than steel, if anything the 135 would be more reliable for a heavier skier, although the 135 heel pins do become notched over time leading to some rattling (but they are replaceable).
    The same is probably true of the Dynafit Low Tech race with its Ti heel fork vs the Dynafit Low Tech Radical.

  20. Hi James, good question.
    During the research I noticed that some had notices about person’s weight. I will go back, collect the info and put it in the notes.
    From some that I recall there seem to be 70kg “threshold” that is common – that means that even me would be above, heck, the whole Canadian men’s team would be above :)

  21. james minifie says:

    Great stuff Stan. One question though. Since many people are choosing to use these bindings for other mountain objectives other than racing, are there any indications that any of the models have user weight restrictions. For example, some light race-oriented mountain bike components have weight restrictions (pedals, wheels, tires). As you know, I am a bigger guy but I still like to move fast through the mountains!!!!!
