Engineering disagrees, sorry.

NNNbc do not overlap the ski making them harder to get on edge, not saying impossible just harder. The bar in the boot is never a tight fit in the binding so the first movement to edge is wasted. Reality is if they went down fine, Olympic courses would have actual hills on them.

The riva etc solved some of these issue with a tighter fit giving a little more edge control. Sure like them for what they were great for going forward, but cable bindings defiantly improved going down.

 

Hey Ziggy watch your words I have been using T4 s , Riva Z + Karhu Guides for a few years on the BHP , I think its a great compromise for winter conditions.
A bit tempted to try something like the
Svartisen GTX® 75mm at 1020 g it doesnt say what size.
BTW this Tuesday 30th is looking like a nice touring day at Falls , 2 of us are going, anyone want to meet up?

 

Link to the lighter Crispi NTN 3 buckle boot.
200 grams lighter per boot than Crispi's EVO NTN or World Cup NTN boots. Comes in white and aloe green or white and yellow.

Nice little telemark video also on that site.

 

You're mixing up the binding and the boot. Talking about engineering.

The bigger variable than the clamp is the torsional rigidity of the boot. See the Glittertind or the Svartisen, not a clapped out rental.

Added:

And you're ignoring the sole ribs.

 

Thanks, normally yes but I'm in the big smoke for a few days.

As posted elsewhere I've started using the Svartisen NNNBC on Epochs. Sweet rig for scooting over the plains.

 

Here is the link to what I agree is a nice video. Looks like Outlaw X binding at 0:09 seconds.

 

How is the fit and the rigidity / control of the Svartisen considering its NNNBC?

 

Will have to agree to disagree, I’ve been on nnnbc, riva’s, chillis, hammerhead’s, o2’s and ntn and I can say to two best ski days of my life we’re getting rid of the nnnbc and shifting to ntn.

 

I went from 3 pin to NNNBC, and thought it was awesome. But then I went to cables, etc etc. The NNNBC was pretty good for kick and glide, but IMO that was about it. Which is fair enough, yes you can turn on Nordic gear, but Telemark is an entirely (though related) seperate discipline IMO. It is not xc.

 

Can you make it a power strap, two buckle boot?

 

The bottom buckle could go at least if the boot tongue fit well enough to keep snow out. Don't know why so many boots have the lower instep buckle. Seems like overkill for the job of sealing the boot. I muse that a lightweight silicone rand under the tounge would do that job for less weight.

There's a limit to the ski size you can control.
Out of interest last winter I put Glittertind boots and NNNBC on Fischer S-Bound 112 (79mm underfoot) and no.
Epochs yes, with the Svartisen.
The big variable as mentioned is the leverage the boot offers.
I bought an ancient pair of ex rental Outbounds last winter and there's no play in the NNNBC clamp.

 

Sorry again but this is meaningless without specifying the ski combos and applications.
If you're talking about a quiver of one it'll have strengths and tradeoffs that you could live with but another skier would reject.
And the big change since I started skiing is that few dedicated skiers have a quiver of one any more. We get horses for courses.

 

I don’t see how it is meaningless, nnnbc are designed for skating not turning. I get you like them but accept they have limitations.

I love my freedom, yep I tour on them but I accept they have limits

 

If you want a binding designed for skating you'd opt for something like a Salomon Pilot.
The BC in NNNBC stands for back country - it's a touring version of the general purpose New Nordic Norm, having a wider baseplate that would overlap a skate ski.

 

When I can only carry 1 pair of boots to Charlottes and snow is soft no probs w T4s + 92mm waist ski.
Ziggy Just wondering how you think the Svartisen 75mm .w. a Guide 78 mm waist would be in softish stuff.??

 

All I can say is that for me the NNNBC version is good for up to 70mm waist when there's icy downhill traverses or I want to edge for turns.

 

Nah my point is that soft snow is easy to edge and would take T4 if its deeper so weaker boots should be OK on a day trip , ice/firm would be the enemy ? .

 

Only been to Charlottes once on the oversnow. Quite a few folk exceeded the luggage limit without consequence.
Depends on the time of course but it stays firmer there than at most other side country.
As a rule of thumb if I don't know what to expect I'd take the heavier gear.

 

Good plan Ziggy, more or less my philosophy for touring.

Far better to make it down perhaps with tired legs than to reach the limit of the equipment and be making survival snowplows. Or worse!

 

First weekend out on new Lynx.
They’re fantastic, ski like the Meijo but just seem ten tonnes more burley.
Same weight but just feel more robust.
Stepping in to them is a dream compared to the Meijo. And easier to press in to tour mode.
Transitions probably faster than your average AT setup, but similar to Meijo.
Mostly just touring last few days so will comment again once I’ve skied en piste and done some big lines.

 

They’re awesome en piste too.
Very solid, with great lead to lead.
Even with ice and chunky snow underfoot they remain a breeze to step in to.

 

Do you just step in and ski or do you tighten the tech toe?
I love mine but i do find the toe loose upon first step in, the pins aren't super tight.

 

Tx pros, 3rd season. Inspected them properly the other night, nothing obvious. My dynafits on my tts setup are way snappier on the click in. Not a super big deal, the lynx is still my preferred binding over my 2 generations of outlaws. But still love to get them perfect!

 

Haven’t had to tighten them at all when not touring, bomber solid and have really pushed them.

 

Got my vernier on.

My dynafits click to 51mm (pin to pin) on first click. Lifting the lock lever doesnt seem to bring them closer.

My lynx click to 54mm and 55mm (l and r are different) on first click, then tighten to an eventual 53mm when the lever is raised.

So appears that the tech toe standard is not too standard? Anyone else care to provide some comparison results?

 

Was thinking the same thing! Stay tuned

 

My mates meidjos were measured at 53mm pin point to pin point. Maybe difference between vernier and rule?

Have emailed 22 designs with questions!

Interestingly my boot cones are 61mm apart, my wifes dh boots are 60.5mm apart. A fair difference from that study?!?!

 

Is the hole pattern for Lynx the standard 22 Designs 6 hole pattern a la Outlaws?

 

Yes it does....of course....see the linked review.
6 holes vs 13 for Meidjos is a big plus for me. Much easier to mount and then swap to other skis with inserts. If I like the way Lynx bindings skis on lower spring tension the separated release capabilty of the Meidjos is less of an advantage over.what looks like a sturdier 22 designs offering.
https://www.gearx.com/blog/2019/03/21/22-designs-lynx-tele-binding-review/

 

Don't mind some pedancy....or is it pedanticness?
8 holes is still 5 less than 13. I do like having some release. Ideally I'll demo both bindings and the Lynx at its lower end of spring tension.

 

Thanks. I crossed posts with you after deciding to not be lazy and find out myself. I do appreciate that 2w Designs kerp their pattern across their bindings and it removes a disincentive for 22 Designs 75mm users who love their current skis to change to NTN.

 

A trip across the border to Wilderness Sports is the answer or perhaps there may be some to demo at the upcoming Backcountry Festival at Hotham Sept 7-8.
