Another chapter in the story of tech binding ramp angle study

I have found that velcro spoilers are enough of a fix for me to adjust to the Alpinist binding flatness.

I have found that velcro spoilers are enough of a fix for me to adjust to the Alpinist binding flatness.

I found that spoilers did nothing for me and I needed a 3/8” shim under the heel. My ankles don’t flex but I still have a natural forward lean so I need positive ramp angle.

not exactly on topic but i have removed the baseplate from my MTN so that i can put a shim under the heelpiece and mount the ATK spacer.

i don't think the shim's height surpasses 3 mm. I have at least 2 grooves of the standard screws still exposed. Should i still opt for longer screws? Has anyone mounted a shim under the heelpiece with normal/standard screws?

You want at least 3 and ideally 4 threads of the screw showing.

I'm surprised at the very high delta on touring bindings vs. alpine.

Are we talking about the same kind of delta? Or do I need to treat them differently across binding classes?

With my new alpinists, the plan was to shim them 3mm to match the ~5mm delta of my Salomon bindings. It seems like a lot of you throw on a lot more than 3mm...

Note that separately, I am sourcing a touring boot with as similar geometry as possible to my resort boots, hence my target of matching binding deltas between systems.

I would measure from the bottom of the boot sole to the floor while in the binding. Published pin delta doesn’t correlate to alpine binding delta most of the time. It’s good for comparing different tech bindings.

There's some discussion (I can't recall where) about touring boots *generally speaking* having different ramp angles than alpine boots. It had to do with the boot boards, the toe vs heel height on touring boots where they're suspended on tech bindings vs alpine boots in alpine clamps etc.

Speaking for myself my alpine boots in alpine bindings have more ramp angle than my touring setups which intuitively makes sense as I ski alpine boots with forefoot/ shin pressure vs touring where I ski fairly neutral.

Dare I say that it may be that everyone is different so ymmv

Agree with all of this, and to add, there may be bigger variation in boot ramp in touring boots than alpine boots since alpine boots have DIN norm toes and heels, and very consistent BSLs across a given shell size in different brands vs touring boots lugs and BSL vary significantly across models and brands.

I do think that the ski and use/style matters too. While it may not be relative to you, as an example, on my skinnier touring skis that are mounted more traditionally (ie -11 to -12), I have similar delta to my alpine bindings (around 5mm) to help the edge hookup and carve. On wider and more progressive powder skis that I ski I in a more slashy manner, I prefer a lower binding delta (0-2mm).

Point being, sometimes you may have to experiment to find what works for your biomechanics, preferences, and setup.
