Poster: A snowHead
|
Just bought 2 pairs of identical skis
Skier 1
Height 1.83m
Weight 95kg
Age 50
Boot sole length 358mm
Skier 2
Height 1.83m
Weight 80kg
Age 20
Boot sole length 328mm
Skier ability specified as the same using same model of boot..
Just wondering why bindings for skier 1 are set at 5.5 and skier 2 at 7.0?

antoeknee,
All those factors you mentioned are taken into account when calculating DIN settings. Haven't worked it out, but at a rough guess I'd say the difference is because of age.

Well, the person's real but it's just a made up name, see?

And boot sole length. Skier 1 has longer feet which provides more pivotal force on the binding, hence a lower DIN.

antoeknee, exactly what beanie1 says. (and the settings are what is recommended in the 2004/05 Salomon binding chart)

Anyway, snowHeads is much more fun if you do.

Am i being really dumb or should that be less pivotal force. If it was more then surely the din would be higher.
Not picking at straws just interested. Someone of the same height and weight but with shorter feet can exert more pressure per square inch. hence why racers ski with as small a boot as possible?

You'll need to Register first of course.

waitingforwinter, Think of the ski acting as a lever on the boot. A smaller boot will have more ski length acting as a lever, hence the higher setting..

Guessed that boot length was a factor but I'd figured that larger boot might have meant higher DIN setting.
The older skier is me so I'm not surprised that setting was lower for age.
Kind of anticipated that as my son (skier 2) was lower in weight the settings would have ended up similar.
Just seems to be such a big difference but interesting that thats whats recommended in the Salomon chart.
Kind of puts my mind to rest a bit now as I was anticipating probelms with too easy ski release, hopefully that shouldn't be a problem.
Can always get them adjusted in resort if its a problem of course.
Thanks to all for your input

antoeknee, the funny thing about DIN settings is that skier height also takes a role, big feet give a greater leverage on the body so the bindings need to release earlier so that you don't get an injury

Obviously lots of factors for DIN settings. I can see the subject is far more complex than it might appear.
Seems logical from what you say about boot size and leverage, my initial reaction was that as we are same height and he's lighter there might not have been much difference in the setting. I'm all for minimising ski injuries and its noticable that the bindings on these new skis are a significant improvement on the bindings from my 3/4 year old skis.
I'm now not concerned that the setting on my skis might have been wrong as from the comments/info here tends to imply that both sets of skis have been setup correctly. I'd have been suprised if they had been wrong but difference just got me wondering.

The binding manufacturers specify a mandatory DIN reduction for over 50'3 when training their techs, that takes no account of the fact that a skier who started late might be a lot better after 50 than before 50, yet still fall into the "middle" category of skier type. (For some reason the binding manufacturers are unable to distinguish between skier levels in the same way that ski schools do, and specify only absolute beginner, intermediate and aggressive expert types).
Consequently, I lie about my age.
- I don't know whether different binding manufacturers specify different DIN settings for a particular individual though. When I rented a pair in the US last January, I was rather surprised when the tech did the calculation and set the DIN 2 points higher than I have set on my own kit.
Maybe one of our gearheads can clarify this.
