increasing kingpin ramp angle?

[mntlion]

Do you know of any way to increase the ramp angle of the kingpins?

new boots (dalbello lupo IT) are feeling good on old skis (hoji and others) but on the new skis/bindings (kingpins on blizzard zero-G) it feels like I'm centered on the ski, but still back of my ideal balance point. Thikning adding a few mm to the heel, or lowering the toe will help this.

anyone done this? can't find much on wildsnow or TGR.

You don't think that's just due to mount point? 4frnts are waaaay forward of Blizzard recommended usually.

[mntlion]

maybe
but I would rather not re-drill
and I skied almost the same ski last year (early cochise release) at the same spot (-1) and liked it
I'm on hoji as my other ski, but also mounted back of center, HATED the raven

looking to add the demo track part of the kingpin to the heel

Wondering if it is your mount point. Been skiing the kingpin on a pair of atomic automatic 117 since last year. They do ski flat though, which i like as it is the most solid feeling touring binding i have ever been on. Reminds me of skiing a pivot.

But with what bindings?

But with what bindings?

last year with adrenalines, that had about 5mm more overall height.

Okay, so measuring from bottom of boot sole rubber to top of ski topskin, what heel and toe values do you have for the frame binding and the Kingpin?

[waxman]

i've got lots of race shim lifter things (technical term for you) if you need to lift 'em
in 1mm to 4mm increments iirc

thanks, I"ll let you know if I need some, will be in fernie this upcoming weekend

I'll check in the am, but the difference between toe and heel was about 5mm on the KP, and about 9mm on my salomons (that I like)

Anybody tried decreasing Kingpin ramp angle? Not sure if needed, but I plan to use a pair of Kingpins for a one-ski travel quiver. Both a bit of inbound as well as winter touring. Skimo estimates delta at 9,5mm, with Ions (which have a bit to much delta) is 11. Beast 16 (which I like) are 6,x mm

Yep, I've done a few for customers. Just add toe shim of your thickness to give you the delta required & use suitably longer screws.

Ok.
Any feedback on how it worked out?

[auvgeek]

Skimo.co also sells B&D toe shims and associated screws for the Kingpin. What specifically are you concerned about? I would be highly surprised if shimming the toe didn't work the same as it does with any other tech binding, which (IME) is great if you want less ramp angle. The only downside is if you're also sensitive to overall stack height. If you are, then you have to decide whether you prefer less overall stack height or more ramp. Or move to an UL binding that has low ramp and low height but less durability.

Personally, I would ski them first and then add a shim if necessary.

[mntlion]

ramp angle is a personal thing, (like boot F lean, like ski flex, like amount of sidecut)

its not a right/wrong, just an option

I like 3mm more heel lift in mine. you might like a toe rise

follow above instructions

[sf]

Ok, thanks.
Not concerned about anything in particular, just bored :-)
Will probably try without shims first as advised. 3,2mm shims if it feels weird

I have two setups both shimmed 1/4" at the toe. After shimming they ski exactly like my alpine setups which is what I was after. 1/4" polycarbonate or lexan works really well as a shim material. I'm a fan of forward lean but really dislike alot of ramp angle.

Nice. AT boots or alpine with tech inserts?

Technica guide pros, so 4 buckle overlap with tech fittings.

If given a choice, I'd use UHMWPE (think white, cutting board material). Go to a plastics fabricator and ask to rummage through the scrap bin.

Finally going to get this done.
Why UHMWPE over polycarbonate?

It tends to be flexible in the cold. Let's hear what @1000-oaks has to say. He's real good with material selection.

FWIW I have enjoyed my ZeroG 108s way more mounted +1.5

[carlh]

I would use HDPE not UHMW or PC as it is less slippery. I have some PC shims I made for dyanfit toes and the bindings will slide around unless you really reef down on the screws. I am planning to remake with HDPE and tighter screw holes.

Ooops, just bought some polycarbonate. Oh, well. Maybe rub it with some sandpaper.

[GeezerSteve]

I've shimmed dozens of tech toes with HDPE over 10+ years, never had a failure nor any problems. HDPE is tougher than shit, stays flexible at very low temps. Polycarbonate is much more brittle.
