i don't actually know the details....

I'm equally ignorant of the exact process razie!

Checked some of the speed ski quiver.  Couldn't get to the back of the closet to get the DHs but here we go

201/33 D2 SG (2012/13)   50/40

205/40 D2 2015 Womens FIS SG 47/37

I got a pair of 2016 Atomic FIS SL 165.

33/26

Can't wait.

uh-oh, so considerably stiffer in the tip - so these are considerably softer  It's ok - he's moving from a 145 to a 165 :) and missed one season!

Why would it be so significantly stiffer in the tip ???

I think you are misreading the handwritten numbers.

I am sure that is 38/28  0r  36/26.

I believe SS is right 38/28 is going be softer than a 158 at 37/27

Thanks. I'll try them back to back when I have snow and report.

I have a pair of 165cm FIS slaloms that are marked with 38/28.

I'm glad I got the "soft" version because I can't imagine anything stiffer!  They are fun to ski though.

These were the only numbers hand-written on the skis. Looks like 33/26 to me, just interested because these are my first Atomics.

Earlier there was talk about the numbers being deflection. If deflection is the first number, is the second number the measured pressure applied for the testing?

some extra stiff tips on those

The tail number looks more like 25 than 26.

Dude - you got a stiff one!!!  I also thought you mis-read that, but it looks like 33/25 to me . ohoho... assuming the numbers are comparable across years.

The first number is the tip the second is the tail. That's my understanding. It is normal for the tail to deflect less at the same force, because it's shorter.

33 - 25 here as well. stiff year. Hey which mounting holes are you using, front or rear? mine came with no guidelines....

i believe it's related to the sole length - let me check

ehh no... my X16 says nothing about that, but i'm sure that's what it is - so you'll have to eyeball it. play pretend and see what numbers the thing can slide to if it fits your sole size or not

or measured by the same drunk austrian guy on that same friday night batch !!!

Good thing about the atomic x bindings is that they can be moved fore and aft with a flip of the lever. Easily done on the hill.

My son's BSL is 295 & my BSL is 283.  It's his ski so I mounted the toe piece on the 2nd set holes initially. On the hill, he was not happy with the feel of the ski. We move the binding ahead 1 notch at a time until he was happy. We ended up moving it 3 notches by the end of the day. Each notch is about 7.5 mm. So that night I just remounted the binding to the front set of holes so the toe piece can be on the center of the toe track. When I borrow his skis I like the ski with the binding moved forward 1 notch. Which seems consistent with our differing BSL.

We do not race so you may want to set up your skis differently.

how did you guys mount the toe binder plate on the sl's? my plate has 3 pre drilled holes but last years x19 has a square 4 pattern.....

Had the same issue - I called then and they said to use just the 3 screws that match... I will do another pair tomorrow

I bought a pair of never used but with bindings installed 2015 Masters 183 GS last spring. I think they were set up for 320 or so BSL. My boots are 295 and when I changed the setting, I couldn't move the binding farther forward than the #4 or so position. I remounted them in the forward mounting holes and was able to get the full range of movement in the varizone adjustment.

Yes, on some Atomic plates, particularly on the speed skis, even using the forward holes you can not always get all the variozone positions if you have a 285 or smaller BSL

2013-2014 158 @ 38/28

here is how i mounted last year and i'm about to mount a new one the same way:

and

that's for a 295mm boot, which is default for this binding - you'll see the markers.

howeber, top is a 2014 158 and bottom is a 2015 165 and the plates are little bit further apart on the 165... don't think it makes any difference...

which reminds me - I dip the screws in loctite blue before screwing them - does that make any difference? I think we're supposed to use some silicon of some kind... the point is to prevent water (or beer) going in, right? i usually fix dirt bikes so i have loctite instead... heh

I've had Loctite react with the plastic on bindings and cause cracks.  I wouldn't use it again.

I've been using Vibra-tite without issue though.

I'm not sure, but don't the screws go into the plate, not the ski? If so shouldn't need to be sealed.

I'm going to use red high temp silicone

Not sure why you would use anything on a plastic plate?   I have done an awful lot of Fischer plates and a lot of Atomic plates and never used anything on them - and never had them fall off!

Okay donkey no use nuthin'

I've never used anything on a plate.  I use the Vibra-tite on binding inserts like quiverkillers and machine screws though as they can back themselves out.

Demoed some 165 FIS SL's yesterday and they were 33/25.  Seems like a trend to a stiffer ski.  They skied both lighter and stiffer than my 38/28's.

I just skied them all day yesterday. They were really stiff but amazing. It is still kind of powdery mix so it wasn't their favored condition.

When I did hit a packed or icy area, they were a dream. Solid, agile, and ready to throw me around when I relaxed.

It really put into perspective of how out of shape I am. Skiing at 100%, halfway down each run I had to take a 15 second break.

I loved 'em.

Along with the change in flex on the new SL skis, Atomic switched from the cap construction to more conventional sandwich and sidewall.  Anyone know why?

My guesses are cost, perception/marketability and or performance.
