I'm not sure about that one, Jim.  As far as I know, the Freeflex hole pattern is the same as most other adult Head/Tyrolia bindings.  According to the Tyrolia tech manual, you can use a number of different bindings on those plates, using the same holes in the plate -- Freeflex, Mojo, LD, and SL.  Of course, the system bindings won't work, nor will rental ones, but the ones mentioned are listed as compatible with all their plates.


I think you are probably right about mounting any Tyrolia binding on the rail.

 ??? ?Are we talking about rails or plates? Sorry if I'm off base on that.  I must have misread.  I thought we were talking Freeflex bindings and plates, and mounting other Head bindings on the latter.

You are correct - wrong word on my part.  :D

Additional data point on binding height. I skied for half a day on a buddy's skis, one of which had an additional plate on one ski to compensate for leg length difference. He was concerned that the different binding heights would make the skis difficult, but, I found that very quickly, the differences made little effect on skiing. I might give a small plus to tipping the ski with the higher mounting point. The placebo effect may have been a factor, but, I think it's more about the skier movements and the ski, rather than small change in height.

Certainly a much easier thing to do with stack height Max...

But gotta say for those curious....it's not only for hard charging, high edge angle  skiing. If you have a hard snow ski that you want to make more repsonsive, more sensitive edge to edge, better feel edge to edge....stack height IMO is a big plus.

Binding stack height makes a BIG difference for skiers that want to put their hip a few inches from the snow.
It's going to take a LOT more than stack height to get my hip a few inches from the snow.
Maybe hip outriggers or some such exo-skeletal support mechanism.

Couple of things:

1. The Head/Tyrolia free flexing plates, those that have oblong holes in the most forward and rearward parts of the plates, actually do permit more free flex for the ski even if you mount a non-free flex binding (like a Mojo 15) on the plate.  This is because the plate reduces the size of the flat spot to the area between the inner sets of screws.  Of course this means that the plate needs to really "float" on those outer screws and Head/Tyrolia is very specific in the mounting instructions about how far those screws should be screwed in.  It wouldn't surprise me at all if a shop mount completely disregarded this fact and they've screwed them in too tight.  I not only check that those screws allow the plate to move once I'm done with my mount, but I also grease the plastic "collars" that ride in the oblong holes to ensure that they keep moving.

2. As already noted, the band between the toe and heel on the freeflex binding models connects the two together to ensure that the distance between them is maintained during flexing so that the forward pressure doesn't change.  I guess somewhere along the way Head/Tyrolia decided that the springs which were supposed to "calm" the ski's rebound energy after flexing really didn't do much for the performance so they decided to scrap the springs.  They were similar in idea to the old Marker piston and the current Blizzard IQ Max pistons.

HA:
A little bit of lubricant where the screws slide in the slots is a great idea.
What would you suggest that wouldn't stiffen up and make things worse in cold weather.
Thanks.

Jim - I recommend Phil Wood Waterproof grease which is good down through below freezing temps.

H-A, thanks for the tip on the grease and over-tight screws.  I just had the Tyrolia CP13 plate installed on my wife's new iM78's, with a non-Freeflex binding...the LD12.  I'm pretty sure they were installed correctly, as the ski flexes extremely well under the plate, but I will check regardless just to make sure.  And smear a dab of grease in there.  Good advice....

Question:  how many times can I re-insert the screws in the holes of the CP13 plate before risking weakening of the screw's grip? I heard that 3 times is the max.  Is this correct?

BTW, I may have mentioned this, but the CP13/LD12 setup is sweet.  Light, no added stiffness, no dead spot, great performance, ability to move bindings fore and aft as needed (with a few minutes work)....it's all good.

Svend:


If this is like the other plates, it is metal. Once you have the hole tapped (created) it should be just like screwing a bolt into a metal nut (as long as you are careful to not cross thread the screw). I would think you could reinsert the screws a lot more times tham three. The concern would be to not over-tighten and strip out the hole in the plate.

Jim, I'm pretty sure that the CP13 plate that I put on the iM78's is not metal.  It has a coating that is the colour of aluminum, but the plate appears to be plastic.  FWIW, the plate on Terryl's Supershape Speed is also a white plastic.  Check your Magnums, I think you'll find the Speedplate on there may be plastic too (but I'm not sure on that, as it's different from the CP13).  Hence the question re. how many times I can sink a screw into a hole....

Don't have my Magnum's any more, upgraded to Fischer Progressor 800 (and really like them).
But you are right, it they are plastic, then much smaller number.
It's hard for me to believe that there's not metal in there somewhere, though.

Can you helicoil them or something once the holes are done?

The guy who does my grinds pulls the bindings before running a ski through the machine, and said he could pull and reinstall bindings quite a lot of times before worrying about any ill effect.  Since most of my skis have plates, I presume he's removing the binding from the plate.  I don't know anything about bindings or plates, though..

Will there be a review forthcoming?  :)
