Binding location 101

post #1 of 7
Thread Starter 
Okay here is my first new thread post - I hope I am worthy!
I want to get a better,general understanding of the rationale behind why bindings are mounted where they are and how deviating from the "prescribed" location either way makes a difference. From what I know most non-rental/demo bindings heel will move somewhat to accomodate some different boot lengths but this generally moves the boot off the mark a bit. I have a pair of demo bindings that have independantly moveable heel and toe, so it seems to me I could actually move my center of gravity fore and aft on those. I also have some demo bindings that only the heel moves and a pair that move the heel and toe at the same time - I would think the latter would put any boot length on the mark. I have seen some mention of a homemade balancer to use for binding location. Is the general intent to put the skiers center of gravity exactly on the center of balance of the ski? Seems to make sense though I have read womens skis are mounted a little ahead.
More specifically I have a pair Salomon pocket rockets I want to re-fit with AT bindings and use soley for ungroomed, off - piste, b.c., and the like. I understand the factory location is somewhat unique on these skis considering they are designed for terrain/park. I don't plan to intentionally "ride switch", "grind a rail", or "huck my carcass"! (Old dog - new trick thing I guess). So I gather I might want to locate new bindings on these differently for my particular purposes. I like to do things myself and as such I believe knowing why things are done is as important as how things are done.

Thank you in advance for any of all your vast and abundant knowledge! Reading this forum is like trying to drink from a firehose!

Dang! I searched BOF the other day and didn't come up with much (musta been under the wrong topic or something???) There's tons here - I have much to read now!

Don't ya just love newbies?

I am learning a lot about this myself, after experimenting with different positions on my skis with RailFlex bindings this year. When I put my boot midsole mark about 7cm behind the ski's sidecut center, my BOF lines up with the sidecut center and the skis have an awesome feel. Even 1cm off that in either direction and I can tell a difference.

My Elans (M666 and Mag 12) had the midsole mark right at that 7cm back position and skied great right out of the box. My other skis tended to put the midsole mark more like 8-11cm back, and needed tweaking.

I have a pair of Public Enemys coming tomorrow, and this will be the first ski I put a fixed (ie, non RailFlex) binding on with the location determined by the BOF method. I will be curious to see how this compares to K2's "nominal" midsole mark.

if you already have railflex bindings, why not just get an extra plate and mount them on your new skis? I bought a pair of PE's on SAC and plan to do that.

I considered that (love the RailFlex -- and already share one binding among two other skis the way you suggest), but wanted to get away from a lifted binding on the PEs so I can get more stability for bumps and future park use.

Having just spent an hour making a paper template to mount my new Salomon bindings, I will say the RF mounting is a LOT easier! That alone is a plus to me. If there was a RF plate/binding with significantly less lift, that would be the optimum solution.

another good read on bind positioning


also, the attached pix is something I read out of the Tyrolia manual.
