Mounting points - how many mm's or cm's does it take for a difference to be noticeable?

post #1 of 12

I see a lot of threads about mounting points and whenever I see someone recommending mounting points in 5mm increments (e.g., -1.5cm), I wonder how half a cm on a 180-ish cm ski could possibly make a difference.  2cm's I could see, and maybe, possible, 1cm if you are really in tune with your skis, but 5mm's?  

 

Unfortunately this recently became more than just a hypothetical question for me because I had my skis ('12 SFB) unintentionally mounted -5mm from the line.  There's no way for me to know if it's actually making a difference because I've never skied these on the line, so I'm just wondering what people's thoughts are on the matter generally, and specifically with respect to a -5mm mount.  Thanks in advance.

I'm pretty sure I wouldn't notice a 5mm difference, but I do notice a 10mm difference on my Shamans.  I have Schizo Griffons on them and experimented with them last year and feel most comfortable and in control with the binding set at -1cm.  I will likely have my next pair of skis mounted at -1cm.

I've heard that about 7mm is the minimum to tell the difference.

You're assuming that the error is purely fore/aft. In that case, yep, about 5 mm seems a lower limit to sense. But just a few mm sideways, meaning toe is not in line with heel, and you'll notice.

It also depends on the flex.   Softer skis - less noticeable.

Rocker also effects mount points, I demo'd the s7's at 3 different mounting points and could tell the difference easily.

It depends.  If that 5mm moves you out of YOUR sweet spot on the ski then you will most likely notice it.  Sometimes 5mm is very obvious to me on one ski and not so much on another.

Hmm.  Well I just measured and while I was told it was -5mm, it actually measured -8mm, so that may make a real difference.

Depends on the ski (big sweet spot will make the shift less noticeable), and if you ski the positions back to back. If you are experienced, you SHOULD notice a difference.

5mm is the diameter of your bolts. You aren't going to notice that.

Depends on conditions.  If trying to get the front hooked up on ice (like after prolonged freezing rain) with a fairly straight ski (old school or gs and above radius), being 5 mm back is noticeable.  If on snow, not so much.  Unless you are trying to rail arcs on a sheet of ice, I wouldn't worry about it; the benefits in added speed make up for the very slight exta effort to get more tip pressure when required.

Definitely not a straight ski - '12 Line SFB.
