Default Trust Ski Manufacturers' Flex Rating

50% is probably close to the limit, tho it depends on how much residual
camber there is. 60% is stiff in a classical ski, stiffer than WC
skiers use. Up to a point in steepness, it's possible to ski stiffer
with a lot of wax - I have a pair of warm carbonlites like that. But I
find it also means having to "work them" a lot, what you describe as
athletic, meaning more energy expended per kick. It's harder doing a
30k race like that. I prefer a ski that kicks easy but rides high
enough to glide, so my again athleticism is going forward more than up
and down.

Btw, this thread has been about RCS's, but Atomic has for some years
used a different flex measurement. I'm told they may have changed
to the standard way of doing it this year. If I recall correctly,
the ones with the tags that have two figures are standard, while the
racing stock isn't (or maybe that's vice versa). I don't know about
Maddhus or Rossi, but they're all NNN now and I use Salomon.

In my case, at 80kg, the actual measurement seems
to be well less than .42, since I can't use more than about 6
layers + a thin binder in front of the ball of the foot before
seeing drag. That's a sign that the ski is too soft to be used as a
universal cold ski. *Which is the point where one goes back to the
seller.


FWIW, I've found that 50% is the softest RCS one might ski (If you
were a 'shuffler'). I wanted to make sure that my current skis are
about 60% of weight, and this range seems to be sufficient to ski
'athletically', use a lot of wax and still get some glide. Pocket
distribution is so important (and tough to test), layers need to be
built up according to how the camber closes.

Which leaves the question, how can 0.42mm, which is 8-9 standard wax
layers, be insufficient? There seem to be at least two answers. First,
skis don't necessarily close in an even manner across the entire kick
zone (I had a pair of Crowns where just squeezing I could see the front
5+ cm closed right off, which explained the drag). Second, the idea is
to match that 0.42mm with the skier's half weight (with adjustment for
skier's preferences). In my case, at 80kg, the actual measurement seems
to be well less than .42, since I can't use more than about 6 layers +

I'm simply amazed that all you wizards always ski on perfectly flat
surfaces, so that you can notice the difference between a few tens of um
of flex on top of the snow surface.

Frankly, I've never been able to do that, except that I'll often run up
a steep hill outside the tracks when I have marginal grip in the track.
I guess this _could_ be due to the less packed snow outside the track,
but that's a difference of mm, not um!

I see a tweak there, Terje. Actually, it's climbing up a moderately
steep hill in the tracks that's my ultimate test of how a ski flexes
for me. I figure at the price of skis in the States, it's worth the
mm.
