Tyrolia Attack 14 Binding Toe Wobble

"I got a pair of ‘25 Tyrolia Attack 14 bindings that claim to work with Alpine boots (ISO 5355)"



That's because they are. Where'd you get your engineering degree?

If your definition of compatible is “marginally functional” then yeah, you have a point.

Have you adjusted the afd? Business card should do it

Are the lugs on your boots heavily worn? Have you tried with another boot?

The boots aren’t the issue and the bindings are properly adjusted. ISO 5355 allows for a tolerance of 69mm +- 2mm on the width of the toe. The toe of my boots measure 68mm. The Tyrolia Attacks don’t account for variance in the boot toe so I’m stuck with wobbly bindings.

These bindings work fine with GripWalk boots. The support for Alpine boots is just a poor design.

Your wings on the binding are not wiggling are they?
if not, I had almost this exact same problem last year with a brand new pair of K2 revolve TW pros in 25.5 size (noteworthy because all other sizes did not have this issue). After measuring the width of the boots and the bindings, the shop technician and I came to the conclusion that neither the boot nor the binding were necessarily out of tolerance. However, the tolerance difference allowed this to happen.

As others have mentioned, it looks like a low AFD. Still shocking how few techs seemed to miss the “pull back on the boot cuff to wheelie the toe and eliminate slack” step before adjustment of the AFD specified in the tech manuals.

The Alpine sole AFD height should be the same as the GW sole height but I think in this case, the misadjusted AFD is actually hitting the rubber grip section of the GW boot sole, not the flat skid pad portion more forward of that.

Attack2 bindings have had a visual test for AFD height since they came out 6 years ago. Because the AFD moves forward AND up, the silver AFD starts to cover up the 2 screw heads above it after adjustment. Screw heads usually end up being 1/3 to 1/2 covered after adjustment, so I usually adjust up so they are at least 1/4 covered before I even start testing on the boot. If you can see the entire screw heads, it hasn’t been properly adjusted yet and is low.

Depending on the boot sole and wear, the AFD height will vary a bit but here’s an idea of what an adjusted AFD looks like with the screw heads visibly getting covered.

Hey Greg, that is good info and lines up with the official instructions from head. Just a heads up that in the latest model the relation between the AFD and mounting screws has changed. See pics:

Are these the same ski that you adjusted the bottom one now? The bottom one looks correct now covering the screw heads partially and the top pic is definitely low with the entire screw head visible. Make sure both skis are like the bottom one and you should be golden!

The set up hasn’t changed even since the original Attack it’s just when they moved to the GW compatible Attack2 in 2018, the AFD now moves forward and up, not just straight up in the original version. Unfortunately techs have been forgetting to yank back on the cuff to eliminate slack for a long time but now it’s easier to see before even testing in the latest versions.

Adjustment of the AFD does not resolve this issue. The AFD can reduce vertical movement of the boot toe but has no impact on lateral movement of the boot toe.

What does the forward pressure indicator look like? Can you snap a pic of that?

The forward pressure is adjusted to spec. The indicator lands almost dead center of the hash marks.

Here’s what it looks like if the forward pressure is too low. This video gives a better look at how much lateral movement is allowed by this binding design when using Alpine boots.

If you go one notch tighter on the forward pressure is it still in the hatches area? Also what happens if you raise the AFD significantly? So it's tight?

I'll try to check mine later, I have Alpine soles and Attacks.

Yeah the forward pressure is as tight as it can be. The forward pressure is the most critical setting on these bindings to reduce slop in the front toe. However it still doesn’t resolve the issue 100%.

It really just comes down to the dimensions of your boots. Your boots can meet the ISO spec but these bindings just aren’t made to work perfectly with every boot. If your boot toe is narrower like mine is (68mm) then you’re just going to have this issue.
