The 300g Touring Binding Thread

I don't think that necessarily translates to lateral heel elasticity. Re atk & mtn, by the time your heel is that far off axis the toe jaws will likely have popped.

Beat me to the punch. Also, the heel pins would have popped out well before the rotation shown in the Trab photo.

A real world test would be interesting, however.

Just a quick update as I have had a lot more time on my Vario 2.0s. The one issue I have had is that the flap for the riser is not very secure. On my ATKs it clips into the pins when I fold it over, but on the Ski Trab it just sits there. It is only an issue when there is some kind of crust and I am breaking trail, as the ski flex causes it to sometimes flip up, which is annoying. Not a deal breaker for me, but it is a shame on a binding that otherwise seems to have been so well designed.

Also I think that the way you clip in with be a really subjective factor. I have now used them in some trickier situations, and I love it, but I can see that for anybody who is a bit less flexible it might be quite difficult.

wouldn't that return to center action just depend on where the flats were milled on binding post ?

the background of these gear picts is always interesting and I'm not too sure about that carpet

It really ties the room together

Can anyone discuss how much ski performance comes from lateral elasticity vs. back and forth elasticity? I'm leaning towards getting the Titan Vario.2, but I wonder if the Gara Titan will be a significant portion of the ski performance for less weight.

I really don't know much about how any of this works.

I'm curious about the Vario2 as well...but this season I'll be playing around with a hybrid setup.

Trab toe (same as Vario2) - for better elasticity than ATK toes (along with a few mm shim to reduce ramp angle)
ATK FR14 2.0 heel - for freeride spacer and good variety of heel risers

Comes in at 650g for the pair. Will have to run leashes, but excited by the possibilities. Lateral release at the toe is the only thing missing.

Tecton toe?

On the Marker Alpinist, I've measured a positive ramp of +3mm on both my Lupo Pro HD and Roxa 130 Ti. Used Alpine soles on both so I could compare measurements with my Pivot 18s set at -1mm ramp.

These are stated as a flat ramp binding with a measured -1.7mm ramp on Wildsnow. Has anyone found this too feel off in that sense and be too flat of a ramp?

Feels too flat for me, too. My ideal is 7.5mm plus or minus 2mm (when the heel is higher than the toe most people call it "positive" ramp) - Dynafit Superlite 2.0 was right on, Salomon MTN/Atomic Backland is fine (8.5), Kingpin was OK (9.5), BD Helio 145/ATK Trofeo felt too flat (.5) . . . interior ramp in AT boots varies as well, many are flatter than typical alpine boots (4 degrees is most common).

In this case, the toe is 3mm higher than the heel, which results in a positive angle up, so I referred to it a positive ramp.

I like my pivots "flat" at -1mm, as opposed to -5mm without the toe shims. I'm wondering how the +3mm on the Alpinist will work out, need to get more days on them to feel it out a bit more. If it's a problem, a rectangle heel shim should not be very difficult to fabricate.

jdadour, your terminology is incorrect. The binding industry refers to positive delta when the heel is taller than the toe and negative delta is when the toe is higher than the heel. There isn't a binding on the market that is made with negative delta, the only way to achieve that is to shim the toe binding.

Silveretta had negative ramp angle IRC.

Pretty much where I fall with Zero Gs ... maybe as flat as 5mm (Helio 200/Haute Route with the adjuster plate) and as ramped as 11mm (Vipecs).

Thanks for clarifying, didn't realize that's how it worked negative vs positive.
