Loose interface on K2 ski/binding

post #1 of 17
Thread Starter 

Hi all.  I have a question about my wife's 2007 K2 Lotta Luv skis with M1 11.0 Marker binding.  There might have been threads about the binding-interface, but I could not find it.  After looking at my wife skiing, I realized that each binding has about 10° of lateral motion.  In other words, the binding does not sit tightly on the interface.  Its hard to believe that the lateral rotation is a design flaw.  I can not find a screw that will tighten the binding on the metal rail interface.  Suggestions...  I am trying to be kind here, I've never seen such a sloppy binding interface.  thanks, cmr

There's something wrong with your wife's bindings. Take the skis to the shop where you bought them. I would bet they will fix them or get you a new pair gratis.

There will be a little slop/play, but it should not be more than a wiggle when twisting by hand.

Thanks for the response.  The binding/interface has lots of slop, really about 10°.  I will take it to a shop, but its still not clear to me how to tighten the binding.  The binding just slides on the rail interface.  I'll let everyone know what happens after I take it back to the shop.

Is there any slop with the boot in the binding?

yeah whats wrong is its system skis that forced her into some of the worst bindings on the market.

ah, what he said, poor system design.  The fact that system bindings are horrible, and and inherently weak binding and you get slop

it is ironic that the 'best' system ski also happen to use markers binding.

 

the Blizzard system with dukes is a really study design. Tats uses it and if he is not breaking them, I dont know who would.

While I am not a big fan of Marker, especially their system bindings, I know a couple people who have them and they aren't sloppy or loose.  I've tuned their skis, and would have noticed if it was as bad as the OP suggests.

It is rather ironic.  The Blizzard system is pretty impressive (though I'm still not a fan of system bidings) and the Duke toe and heel are really well made and well designed

The Blizzard "IQ" track is in fact (IMO) the best of the systems, although the Tyrolia railflex is also very good. Bad mouthing systems in general is not correct as those two are just fine. I agree however that the K2 deal is weak at best.

 

FWIW.....The Blizzard "slider" interface may in fact turn out to be exceptional. The "other Jim" is in St Anton right now with a 2010 Argos mounted with a slider/Dynafit and he is carrying an IQ 5:14 binding with the IQ centermount to slide when appropriate. Report when he gets back.

I wasn't actually bad-mouthing system in general Jim. I said that I don't like them.  By that I meant that they do not work for me.  There are definitely some decent systems out there and they can be fine.

Back after a few days of skiing.  OK, the binding still have the same lateral slop with the boots in the bindings.  It seems that the metal rail and binding interface get more and more sloppy with time.  I will bring it back to the store. New binding will have the same problem after a season of use.  Too bad I did not purchase flat skis or skis with plates.  cmr

I have some Head skis with Railflex system that work great for me.

I discussed the K2 Lotta Luv - Marker ski/binding interface problem with a few ski techs. I also removed the bindings off of the rail interface for inspection.  I think that the interface/binding is poorly designed. The binding mount onto a place shoe that fits on the rail interface.  The metal rail sits on the plastic shoe - thus the bindings rely on a plastic-metal connection.  As the ski techs mentioned, 90% of the public with not know the different,.  They thought that a few mm slop in the interface produced about 10° lateral movement - "so what, the ski are still flat and nobody could feel the lateral motion in the binding.  .

 

Next time around, I will make sure that my wife gets flat skis.  Oh yes, the skis are a few months past the warranty. Even with new marker binding, the interface/binding will have the same problem after a season of use.  cmr

I've found that if one person has a problem like this they may not be alone.  Yet this is the only reference I can google out for loose K2/MX bindings.  

 

My son has a pair of K2 Recons with Marker integrated bindings and they seem to have the same issue described here.  The toe pieces are loose, one more than the other, but they seem to tighten up when you put in a boot.   So the shop I had them at seems to think that's OK.   And there's no adjustment for this play.    But when we add in 190 lbs of seventeen year old skier,  he says they still feels loose enough to notice when he's skiing.  

 

Now my problem is I got these from Craigslist a two years ago, they were unused, unmounted, 'new in box', however they were at least a year old when I got them, probably 07/08.   So I really don't have a shop I feel I can lean on to force a fix or a swap out.   Hey - they were an integrated ski/binding system, I didn't expect problems like this!    They have only been used one season now, so this is kind of a bummer.

 

I'm thinking that perhaps the rail flange is bending up a bit, or maybe I could slip some shims in or something.   Or could I contact Marker or K2 with this issue?  Any ideas or suggestions of what I should do?

 

BTW, I'm a long time K2 skier, my own skis are new this year - flat 09/10 Recons with Salomon Z12 ti.    I couldn't find a good price on the integrated version, and now I'm glad I didn't..
