diamir crampons

post #1 of 20
Thread Starter 
I bought the diamir crampons for my freerides but cannot quite figure out how the two fit together.

please help.

If you can return them unused, do it. The Diamir crampon only hits the snow with the heel flat. When you go up on the high heel it doesn't touch the snow. Who needs crampons on the flats????

Maybe they fixed them, but check out if the teeth touch the snow in the high position.

Hmmmm -- Last week on Washington Pass I was bootpacking a alope too steep and icy to skin when a guy blew by me on his Fritschi crampons. Posts on high. They seemed to work for him. I ordered a pair that evening and hope to put them to good use on Baker this weekend.

Good to hear that. They must have figured out that they are used to go uphill. I ski Dynafit but last year I climbed Mt. Hood with a friend on Frit's and he definitely had the air tooth problem.

Are you getting snow up there? We had over a foot of new on top of Bachelor this morning. Wild weather too.

Some odd comments here. I can tell you I've not had any problems with my Fritchi's. I've been using Silvretta's since the mid 80's and Fritchi's since about '90. Never had a problem with either.

Back to the original question....do you think there is any way my friend could have had his crampons on wrong? Or do they have long tooth/short tooth models? They seemed good and solid on the low heel setting.

There's only one tooth length on the Fristschi ski crampons. They do work better (get more bite) if you are lower down on the climbing peg. There's less bite the higher you go on the climbing peg. Technique might allow some people to climb with less sideways slippage even with the peg at a higher setting. I've had to flatten out my traverse angle and go with a lower peg setting under some slick conditions.

RCrumb has the correct way of snapping them in place.

The steeper the heal postion the further the crampon is from the snow, that's why I use the ski alp ski crampon instead, it fixed directly to the ski...ie
it works better.

The Diamir crampons work perfectly well for their intended purpose: enhanced security on switchback traversing skintracks up steep slopes. If the highest heel elevator position is being used in such a situation, that means that the skintrack angle is too steep to be efficient. (Note that Andrew McLean, formerly a strong proponent of steep skintrack angles, has now realized how much more efficient more shallow angles are now that he’s been competing in randonnee rallies.) Plus the additional leverage for angulation from the highest heel elevator position increases the chance of inadvertently flipping the ski over (which of course is a very bad move in such a situation).

And the big advantage of being attached to the central rail is that the crampon is out of the way when sliding the ski forward on each stride. By contrast, a crampon fixed to the ski either creates lots of drag or forces the skier to lift the ski off the snow on each stride - either way, very inefficient.

The earliest Diamir crampons though were a bit shorter, since the original Diamirs had no plastic lifters. So one of those combined with the higher lifters on the Freeride would be a bit short.

As JS says, I thought the idea was you want the crampons to be retracted when the heel is elevated and you are sliding the skis forward. I haven't actually used mine, Eastern "powder" (and roots, rocks and tree stumps) being so much harder that the Diamir crampons.

Sorry but it's very efficient, the diamir crampon is off the snow when you need the most holding power but the fixed crampon slides effortlessly forward grabbing at the critical moment. It doesn't take much for the skintrack to get steep, at least here in the Rockies, and then you need your highest heel position.

I'm sure you know what you're talking about. Here in the East, the last time I wore crampons in my winter travels I ended up breaking the points off. That was a year when the "powder" was especially thin. I long for conditions when I can actually test my Freeride crampons. Maybe next season?

This prompts an interesting quantitative analysis -

Number of earned ski days this past season in the East that entailed skinning yet were not at closed ski areas (since they always have ascent routes gentle enough not to require ski crampons):

Number of days on which ski crampons were deployed:
2 (i.e., on one day, first skinned up to top of GoS Gully #3, then skinned up to Hillman’s just above the Y split, to where the narrow chute opens up in the steep broad snowfield; one other day, booted it up through Tucks, but then used ski crampons for traverse over to NE snowfields on way to summit)

Number of earned ski days out West:
Number of crampon deployments:
6 or 7

So, yeah, they occasionally come in handy out East, but out West, pretty much essential gear.

Interesting, I've skiied Tuckermans many times, and the upper snow fields as well, but never with randonnee gear. On the other hand, back when I was in my prime, the boots at least were a lot easier to walk in than todays alpine boots. I've always booted or snowshoed up those places. I recently set up a pair of skis with Silvretta 500's because they fit mountainerring boots as well as alpine/randonee boots. I'm looking forward to trying them, with my mountaineering boots as well as with the Garmonts. I hadn't realized ski cramponsere so useful. They seem kind of fragile. Are you speaking of using them in lieu of skins or with skins?

Ski crampons are useful when needed but with phat skis and the hugh surface area
of custom cut skins these days, ski crampons are getting less use. I skied 4 days in the ski area and skied a total of 45 days. Used the crampons twice, in icy steep wind
blown conditions. In the last few years the only place I've consistently used them is in Europe, on long ski tours, other wise they seem to sit in the pack.

Ski crampons are always used with skins. (Although on many tours ski crampons can be used in lieu of boot crampons.) Definitely not in the least big fragile.
And wide skis combined with full-width custom-trimmed skins don’t lessen the need for ski crampons, since the point is not enhanced traction along the longitudinal axis of the ski (or whatever ya call it, i.e., assuring the ski doesn’t slip back relative to its direction of travel), but rather the point is providing more edge grip.

Oops, addendum:
Re wide skis + trimmed skins being a partial substitute for ski crampons, I was thinking of a skintrack traverse at a given angle.
But of course, wide skis + trimmed skins often allow a direct skintrack to be taken in lieu of a switchbacking skintrack. So I now see your point how greater skin traction has lessened the need for ski crampons under certain conditions - sorry about that!

I'm taking your word for this at the moment since I haven't tried my Freeride crampons yet but I am sceptical. These things are made of sheet metal and I used to snap the points and bend forged boot crampons? I guess one reason I've been reluctant to try them out is that they look like they'd fold up on ice but you say they are not fragile? They do look as if they'd be the cat's meow on crust. Looking forward to using them. Now for winter...............................

I've used the same pair for five years. This past season I used them 8 or 9 times, maybe take 6 as the avg per season, so five yrs times 6 per season means I've deployed them on about 30 outings.
Now on a typically outing they're in use for maybe only an hour or so out of the entire tour. And usually it's not on super-firm surfaces. But still, I did use them on pretty solid ice once (mainly just to test them out the first time). And they're still in perfectly good shape.
Also, I've heard of freak failures of just about every piece of ski mountaineering gear, but I've never heard of a ski crampon failure. Seems like it's the only thing that can't break in the backcountry.
