Question on binding

post #1 of 4
Thread Starter 
Please excuse my ignorance, I have couple of questions on ski binding, would someone please answer them for me:

1/. In the old days, a piece of cord was used to stop runaway skis when skiers took a tumble, the use of this cord disappeared when ski brake was introduced. Ski brakes work perfectly but what about when you go off-piste and skiing in deep powder? Do you still tie your skis to your feet with a piece if cord or do you crank up the DIN setting on your binding so that it won't come off when you fall?

2/. We have been talking about DIN setting and the importance of setting it right, but be practical how accurate can you set it - to 0.1, 0.25, 0.5 or what?

Most powder skiers use either a long powder "cord" to help mark their ski when it releases. The cord is typically flat tape, folded and tucked under your pant leg. When you release, it unfurls and hopefully is visible when it stops. Occasionally, it isn't and then you have a problem. A release strap works but then you have the potential of a windmilling ski or getting stuck in an awkward position with both you and the ski immoveable due to the powder. This will require releasing the strap to allow you to reposition yourself to reset your ski. Rare but it does happen.

Your second questions is a bit confusing. DIN settings are usually specified at 0.5 intervals on the binding charts. Occasionally, a junior binding will specify DIN settings at 0.25 intervals. I forget what the ft-lb difference is in each DIN number but there is a degree of latitude in setting your bindings. Most charts provide a torque range for each DIN setting since bindings springs degrade over time. Being off a fraction of a DIN will not cause a significant problem. Many skiers adjust their DIN settings higher than the charts based on experience.

Remember to release your binding tension during the summer! :

fudman22 - Many thanks.

So, do you think cranking up the binding DIN setting is a bad idea in steep deep powder situation?

The reason I asked about the accuracy of the DIN setting was because I have seen skier tabulated and said they set their binding tension at (say) 9.3 or 10.7, and I thought surely it could not be set at that accuracy, nearest 0.5 is fine but nearest 0.1 no way (unless someone come out with a digital indicator).

Merry Christmas.

I would only crank up the DIN if you are experiencing pre-releases. That is if your bindings are clearly releasing you before you feel any significant torque on your limbs. To do it just to avoid having to search for a ski is NOT really a good idea as you may wind up having to take an unplanned sled ride down the hill.
The actual DIN setting you need depends on many factors (ability, speed, terrain, snow conditions, skiing style, etc.). I used to have to crank them up a full DIN because I skied eastern bumps and the anti-shock recovery in the toe piece was not fast enough to completely reset before the next icy bump would kick me out of the ski. It really stunk to literally ski out of my binding and still be on my feet and moving forward, only to bite the big one at the next bump.
The spacing between some binding DIN indicators can allow for small incremental settings. However, even new bindings can have different torque values for the same DIN settings (within their allowable tolerance range). As bindings age (and when people forget to loosen their settings), springs degrade and the settings will deviate from their original torque values. Hence, you will probably experience more pre-releases, when using the same DIN setting, as your bindings age and the springs degrade.
