insta stories, sorry about the format don't feel like transcribing:





someone get on that pre order

? So ATK sells these Hy Bindingungs uncertified and makes the buyer a tester? If the product is bound to hit the market in Fall 2025 but a small number is sold right now this can not be the final design. I would stay away untill 2026.

I was excited for this release, but I admit I’m not seeing it.

A step in the right direction, but a bit too much weirdness going on.

right, wild they are making randoms be their beta testers on pre production and they have to pay for the privilege to do it.

[FloridaSnow]

Well as expected, they all sold out

But isn't the elasticity of a binding measured as the return to center distance?

What makes me confused is that, if I understand everything correctly, it has been stated that elasticity is measured per "single side", so that the 52 mm of the STH2 or the 47 mm of the shift is an apples-to-apples number with the 18 mm of the HY. But in the two tests referenced above, one by you (?) and one by wildsnow the results seem to both be very consistent with the thought above that the HY with a stated 18 mm "single side" elasticity would correspond to 36 mm when comparing the numbers given for the alpine bindings, since the only other binding (that I know of) that explicitly states "single side" elasticity is the Tecton at 13 mm: https://fritschi.swiss/en/bindings/tecton.php .

Now, the table you supplied lists Tecton at 26 mm (=2 x 13mm), and the Wildsnow tests show that the return to center (=elasticity?) of Tecton is 17 mm (~13 mm, or at least a little closer to 13 mm than 26 mm) and for the Shift 22 mm (~47 mm / 2). All this I think very much contradicts that the "single side" toe elasticity is an apples-to-apples comparison with the no-explicitly-stated single side toe elasticity of the alpine bindings. It also seems weird that ATK and Fritschi would feel the need to explicitly state that it's toe elasticity "per side" if that was already the standard for measuring.

I really have not been following this discussion in detail and I don't know much about ATKs or the newer generation of elastic touring bindings in general. However, I think some of the numbers being cited for elasticity of alpine bindings seem unlikely.

The width of a conventional adult alpine ski boot sole, ISO 5355, is 69mm. I find it hard to believe that a Salomon STH2 or other alpine binding could have 52mm of one-sided elasticity at the toe. One would be pulling the boot to the side by 75% of its width. I'm at my relatives' and don't have an alpine boot or binding to play with, but I'd think if the boot moves that far it's coming out.

I don't know where the 52mm number originated. In another of his posts on elasticity, https://wildsnow.com/20514/tech-bind...ticity-travel/ Lou Dawson says 20mm for a Salomon alpine binding, doesn't say which one. So I could believe 26mm for a one-sided number, but 52mm seems too much.

I think everything about the binding looks well done, but for whatever it's worth I just cut the breaks off a shift (leaving the most minimal piece for stomp block and riser), and replaced the afd with an ATK freeride spacer. The weight is under 675g.

I'll post more in the shift thread, but for those that don't mind taking a hacksaw to shit, you can get a better binding at the around the same weight.

where did you get your penchant for fucking around with bindings kid? [emoji848][emoji12]

Please share, very intrigued.

wait I’m confused. Are you trying to say the shift is a better binding than the HY? Hard disagree if so.

[JRainey]

Never skied the Hy, but think knowing what we know now, it's pretty clear the Shift is designed with less compromises. (Even though it's a 12 din kids binding, at best).

What I'm trying is to take the binding with less compromises and introduce compromises, but just in the area where I can live with (no brakes for touring, and simpler afd)

The Hy very well might be a better "touring binding" out of the box, but I'm not going to buy it. It was a good reminder that I should take the knife to Shifts that I wasn't using.

What I really dig about your described mod is that you’ve taken a hacksaw to the two things that most people don’t like about shifts- the brakes and the adjustable afd - instead of “fixing” them.

[also posted in the MYOFS thread] Re: ATK freeraider 15: anyone know what size Allen wrench is needed for the freeride spacer shims? It seems to be somewhere between 2 & 2.5mm (seemingly the only two I have that are close). Thx!

[whatsupdoc]

On my Raider 12s with the push button rear brake I have one freeride spacer that’s tiny Phillips and the other is T10


Edited because the emoji curse is still with us

People have been mentioning the toe height in uphill mode

[harig]

I have an older version of the Crest (the version with one flap only) and was thinking of upgrading to a newer version of the Crest (which still seems not to be the latest one, but already has 2 magneto flaps and the AP brake system but still has the asymmetric spring design and old lever in the toe piece)

Do both versions share the same mountig hole pattern? I´d like to avoid drilling further holes in the Backland UL Carbon Ski

and one additional question: ATK states a max. permissible load (skier + gear) of 65kg for the Crest 8 while I weight fully equipped like 80kg.
The Z value of up to 8 from the Crest seems still OK for my style of skiing (as my Crest are set to 7 atm), just wondering about the low load rating of 65kg...I assumed the only difference between the Crest8 and the Crest10 are differnt spring rates of the springs in the heel piece used...
Any thoughts or concerns using that binding with a 80kg skier?

thanks

[Tjaardbreeuwer]

I have both 8 and 10 Crests, and they look the same, so I wouldn’t be worried about that weight thing, as long as the release values work for you.

Check Skimo for the mount pattern, but I don’t think it changed until the new toes.

Do note that the AP brake raises the heel, so delta increases, until you go to the new taller toe design.

[harig]

Thanks for your reply and the hint with the different delta value-crazy that so many models and even variants of that binding exist...
In general a different delta can be compensated in downhil mode by a different lean adjustment of the boot, is that correct or do I miss another point here beside the fact that flat mode in walking position is also slightly `steeper` with a higher delta?

I saw a link once in that forum with all the delta values of many different brands bindings but can not find it anymore-someone pls has a link?

I checked the Skimo page but could not find any mounting hole patterns there.

The angle of your foot and the angle of your shin translate to how skiing feels differently

here is the mountain pattern info:

and here is the delta:

https://skimo.co/pin-heights?srsltid...NDUD5isMOHTxkN

And no, binding delta, which creates ramp angle on your foot, is not the same as forward lean. Both will move your knee forward, but with a difference in your ankle angle, so not the same from a bio mechanical standpoint.

You can of course shim the toe to reduce ramp. But if you want a low ramp, you would need a lot of shim for that binding.
