You determined that you could get your AT boots into your bindings. You did not observe the forward pressure indicator to insure that forward pressure was correct and you did not have the release function checked by a reputable ski mechanic. Yes... but I've been doing like that for ages. 36 years of skiing and the last 25 without a mechanic. Actually after I broke my former skis I took the bindings in question to the authorised ski service and they confirmed the bindings still worked fine. So I attached them to the next pair of skis and they never caused any problems... TA |

You mean the indicator on the front binding??? Of course I did check that. I did set the usual settings (plus 0.5) and then I tested that (but in the home static environment :-). Later on in the mountains I realised the bindings released every time when I was skiing through the crud on the high speed... TA |

VtSkier wrote: There are three indicators on most bindings in general and on Markers in particular. The one you are noting above is the DIN indicator for the toepiece. There is a similar indicator for the heel. Right. There is also an adjustment for how much pressure the heel piece imparts to the boot sole and so the toepiece. Part of this adjuster is usually an indicator that tells you when the adjustment is correct when observed WITH THE BOOT IN PLACE. For a Marker step-in this is a large screw head near the bottom and rear of the toepiece. This screw head needs to be flush with the housing when forward pressure is correct. On the MRR, with its two large springs on either side, I don't know for sure where the adjuster is, but it's there someplace. I cannot see anything like that. Nor in front neither in rear binding... If a DIN setting of 5.0 works with your alpine boots, it would be OK for your AT boots. However, it may be too light for anything except cruisers and all else being correct, this may be the source of your troubles. Static testing of bindings as you describe is OK to test function, but there is no replacement for proper testing by a mechanic with the proper equipment. There are too many variables. For instance the length of the boot sole is as important as skier weight and ability for release setting. It's a function of lever arm length. I usually set the bindings to 6/7. Sometimes more - up to 9. I know my bindings and I know what setting should be set in which conditions. They call it an 'experience'. How can a machine (which never seen any slopes) test the bindings?? 'There are too many variables' The machine may only check if the bindings are compatible with the standards (DIN). Of course in a shop they ask you about your skiing ability, weight,..., they are taking your boots, and so on. But the result is approximate only... I used that (and other) bindings for years. The only thing is all of them had the standard (alpine) sole. And there was my mistake, presumably... You have described the DIN indicator on the toepiece and asked me if it's the forward pressure indicator. Because there is no any indicators others than DIN indicator in my bindings.. TA |

The idea is that when the binding length is properly set, the boot sole is slightly longer than the toe-heel distance of the binding - when you click into the binding the heel piece moves rearward slightly to compensate. How much it moves rearward is carefully controlled, for the release functions depend on this pressure. So the manufacturers put a mark on one piece of the heel binding and a range on the other piece and when the boot is clicked in the mark must be within the range. This can be as complex as actual grooves etched into the metal (or molded into the plastic) or as simple as a particular screw or rivet lining up with another - different for every binding and a function of design, not of DIN requirements. If the heel piece doesn't move into the proper preload range the binding release function is compromised. |

Like I said, it's there someplace. On the heel (rear binding). I went looking for a picture of this binding but apparently Marker is not bringing it into the US any more. It's not shown on their website. Any other pictures I could find were too small. Oooops. Shame on me. I used that (and other) bindings for years. The only thing is all of them had the standard (alpine) sole. And there was my mistake, presumably... In one post, you said that you had "moved the binding from one ski to another" or something like that. In other words, you mounted the bindings yourself. How did you set the boot sole length for your alpine boots once you had the bindings on the skis? You have described the DIN indicator on the toepiece and asked me if it's the forward pressure indicator. Because there is no any indicators others than DIN indicator in my bindings.. Well there is, it's just that your "experience" isn't enough to discover how your binding works. As I pointed out earlier, my AT boots work fine with both my Marker step-ins (same toe, different heel from yours) and my Tyrolia step ins, except that I need to adjust forward pressure, which you might be calling "boot sole length adjustment" because the boot soles of each pair of boots is different. [...] I am so sorry. You are absolutely right. I know there was that 'forward pressure indicator' in Marker Rotamat - 15 years ago. And I used it then. The indicator (actually there were two of them - on each 'spring') was clearly visible. But it was before the rotamat step-in era... In Marker Rotamat Step-Ins the indicators are just 2 tiny notches... For the last 15 years I had that bindings in every pair of skis (but I never mounted them myself). And I used almost the same boots (with the same sole length - always Lange) And I had just forgotten these indicators/regulators exist... Moreover you said 'For a Marker step-in this is a large screw head near the bottom and rear of the toepiece.' So I was looking for something like that at the toe/front part of the bindings and still was not able to find anything. But they are in fact these bolts/screws within the rear springs... I've just realised what did you mean. And - 'the regulation' took few seconds... .... I am rally thinking about seppuku or something like that... Regards TA |

Any other pictures I could find were too small. http://www.voelklfanclub.ru/catalogs..._sc_racing.jpg Still to small to see anything... But the case is closed. :-) BTW I've just visited European, Japanese, and American Marker sites. They do not offer Rotamats on any market anymore. And those new Markers are SO ugly. :-( Fortunately I switched to Naxos... But I will keep my Rotamats - the last real Marker binding - in a token of remembrance (sorry for that strange language - is this still English?)... TA |
