Thread: Green Mountain Freeride AT Binding

The Green Mtn Freeride boys (Lars+Silas Chickering-Ayers) are trying to develop a touring binding for skiers who need absolute confidence in their bindings in the backcountry but who do not want to sacrifice touring ease or comfort.

The big picture: A Tyrolia 18 din race binding heel is mounted on a slight riser plate. The toe is mounted on a machined aluminum plate (thin and light, just enough to screw into while maintaining stiffness). The toe plate slides into an aluminum housing that is mounted to the ski, and is held in place by a metal pin with a clip to hold it in place. Another toe plate is mounted with a Plum tech toepiece. To switch modes, the toe plates are swapped. This allows a free-pivot tour mode with no lifted weight. The ski brake is replaced with a plastic stomp pad with an integrated climbing bar.

They also have a jig to guide you in drilling out the toes of your alpine boots. An allen cap screw is countersunk into each side of the toe of each boot in the exact location of tech-style toe pins.

Stack height will be ~3/4" lower than a Duke. Weight for the Tyrolia 18 and plates is claimed "less than a standard high din alpine binding," will try to get specifics. Skis like and has the durability of a race binding, tours like a Dynafit with no lifted weight, and is lower and lighter than a Duke.

Pricepoint will be $750 for the Tyrolia 18, plates, Plum toes, and Allen screws for your boots. AT boots with DIN soles and tech fittings will work as well. It is expensive, but it is more functional and durable than the current competition, and unfortunately costs are high for this project.

Please post below if you're interested or have any questions!

???? No thanks.

You don't ski on the pins, you only tour on them. They don't have to be that bomber. That being said, a m6 allen cap screw threaded an inch into a plug boot toe is pretty bomber.

I love the out of the box thinking.

Burly alpine binder with no lifted heel weight = innovation

What is their plan for adjustable heel risers or posts?

I've been thinking about something like this for awhile. I was thinking you could use a Tyrolia rail binding to accomplish some of this possibly?

I've thought along these lines myself, and have talked to others doing the same. I'm sure there are a million ways you could vary this to make it work, and work well. Luckily, Lars and Silas acted on it, tested it, polished the design, and are releasing their hard work for us to use.

The plastic stomp pad that replaces the brake has a 22designs or similar spring loaded heel riser built into it. For now, the binding is either up or down like a Duke. Good news is that a modified stomp pad with multiple riser options would be the cheapest and easiest part of the binding to upgrade.

High-T
long time no ski
I watched ya at the bird comp nice line
Wasatch powder skis would be stoked to help your bros distribute otherwise market, and get these on skiers feet
It's what we do
part of the mission statements
should theses come to fruitation, please feel free to contact us we love to do bidness
bro

Thanks Dibs! Will definitely be in touch. Hit you up when I'm out that way this year, we should ski.

man. good for them putting in the work and all. i'd love to see pics. from the description it seems like lots of shit to mess with and break. i'll put myself in the cautiously optimistic category, i'm excited with the amount of testing and feedback salomon has been doing with the new binding that i've seen firsthand, that that excites me more at this point.

Sounds like a cool idea. Would love to see pics.

Ski:


Walk:

That actually looks really damn nice!

Good idea with the drilling out of alpine boots too, as long as it´s just for the up, it should hold up just fine.

Do you sell a separate mounting plate and riser for the heel of the plums too? Convert your existing at-rig, but still be able to use it as a pure tech setup?

I thought this was a joke the first time I read about it.

personally I see this as a lot better than mdf and a similiar niche
strong thinkin outside the box work
We will be all over this should your green bros choose WPS
Ask them if they fish and would like to discuss matters in our mobile drift boat office sometime
Thanxs
wps facefuck friend request sent to your bro to discuss further

Don't think that is in the works, but I'm sure it wouldn't be too hard using a Sollyfit style heel plate. Two mounting options, one for tech heel, one for alpine heel.

For now the heel is lifted with a simple plastic lifter in the same hole pattern as the Tyrolia heel piece.

That system looks really trick, very cool.

Have you done stress-strain testing on the the boot post-drilling vs. pre? I would be interested to see some data on strain to failure...

Skaalp reborn... kinda

Looks similar the Voile plates/pucks us splitboarders use, which is pretty damn bomber. In fact a lot of hardboot splitters run tech for the up and plates for the down. My only concern would be icing if both the plate and the housing they slide into are aluminum. Don't forget the pam in the morning I guess.

That ski has wayyyy too much sidewall to think they are actually testing this product. big but seriously, looks bomber and a sick evolution. so stoked they boys are making this project a reality.

sooo....no brakes?

no breaks

Not hating, but if you tour with that setup you better hope you have friends touring on original hammerheads, the only binding I can think of that would take more time to change from tour to ski mode than this design. Also, with no brakes and alpine skiers used to having them, I foresee some skis taking off down the fall line alone.

tom- you might suggest to those cats to put a brake on the binding, use a band to hold the brake up while touring, and have a very small riser than mounts in between the toe and heel. or better yet, mounts to the dynafit toe block, so it is not there when you are skiing.

The search for the Holy Grail of alpine touring. Nice job!

There was a similar idea that people used to do with P12/Axial demo bindings.

To tour, just slide the heel back on the track. Slide the toe off and slide on a new demo toe plate that has a a butchered alpine trecker mounted to it or a tech binding toe.

Flip lifters or no lift. You could remove the heel piece and put in a lift plate, but that's annoying.

It worked well. It was a light. It was a little annoying. P12 demos are great bindings but certainly no 18 din on a metal plate.
