Technical effects of binding placement fore and aft - Page 4

post #91 of 95

Artski:

Before you get to excited about Bud's reply he and I won't be there until end of March not end of April.  However, if you read through the research I did and I think the link to it is here somewhere you should be able to determine how to do your own testing.

another anecdotal experience regarding shifting binding placement-

 

I was on my 80 mm waist Salomon Scream Ltd with Tyrolia Railflex LD12 bindings this past week out in Innsbruck, Austria.  I ski these in not the northeast because they have minimal side cut and I think they ski well in powder, soft snow and spring crud.  I can;t get them to hold too well on hard pack though.

 

We got powder conditions the entire week and going off piste was awesome.  I usually just leave the bindings in the neutral position as I have never felt the need to move them.  In powder which is usually a rarity for me to ski, I usually have my skis flat to the snow and keep my weight forward.  Occasionally, my tips get a little "squirelly" in powder.

 

I moved my bindings to the rear most postion which is just a mere 15 mm difference than usual.  Maybe it was a "placebo" effect but in the powder, to me the difference felt like night and day.  I thought I might derive some added benefit from changing the position but I was pleasantly surprised to find that my balance in the powder was better, had better stability and control plus my tips were mostly surfing over the powder whenever I took the time to observe them.  another unintended effect, it seemed like for some reason, I could turn quicker and more decisively in the powder.  Usually, when I get in the powder, my skis seem to have a mind of their own and I am along for the ride.  so it was pretty enjoyable for me-jumping into bowls and skiing between catwalks, pretty much knocking over piles of snow and skiing over variable crud.

 

One of the days I was at a mountain with mostly hardpack conditions that we went to only because the bulk of the trails were below the treeline.  fog, vertigo and whiteout conditions was a reoccuring issue this trip so we had to see out a couple of lower elevation mountains.  So I decided to tryout the forward most position to see if it helped me make faster turns on moguls and hardpack.  I didn;t think a change of 30 mm would be so noticeable but my skis almost felt unskiable.  the tails of the skis kept getting hung up and I found myself making longer turns with less control.  I didn;t feel like taking too much time to get used to it so I switched back to the rearmost position. 

 

suffice to say, I think I will be leaving these skis in the rear most position and seeking out as much off piste action as I can get.

tekweezle - do some research on BoF mounting position and figure out how a BoF mount compares to the rear position on your Railflex.  I'll bet dollars to donuts that the rear position is very close (if not right on) a BoF mount.

 

I want all the ski manufacturers to start marking the center of the running surface on skis (along with the midsole mount position if they have to).  It's not a big deal to find the CRS, but if manufacturers would start printing them on skis then I think more skiers would finally get a clue that the binding mount mark (meant to align with a boot midsole mark) on most skis is merely a suggestion and not an absolute.  Even the park/pipe/freestyle skis with multiple mount marks are improving awareness, but in many ways they also add to the confusion.

 

I promise that most skiers, like 99%, are going to enjoy their skis and skiing much more if they would just mount their bindings so that their BoF is aligned with the CRS.  It's unbelievably important, but so far outside of the norm for the majority of the skiing population.

another thing I did notice with the bindings in the rear most position, on hardpack I found myself skidding the tails more.  this didn;t seem to hurt or impede me in powder and soft moguls. 

 

However, In the neutral position, I could have sworn that my turns were much more even and rounded.

Guys,

 

I made this thread into a wiki. Please have a look and feel free to edit it:
