All-Mountain-Ski Definition

post #1 of 10
Thread Starter 

Hi there, 

I am from Switzerland and I want to know how u guys would describe an all mountain Ski? What r the most important things about it and where do u use them? I have built a ski by myself and now i have to write an essay, test my skis and compare them with two professional skis for my final mark on college. I need an exact definition for an All-Mountain-Ski. If u have an idea how to carry out the comparison between the skis or how to find out the radius, stiffness and other important things.

I'll take a shot. It's a ski most high end recreational skiers are skiing. Some may have a carving ski but for most the first weapon of choice is a ski with 88-98mm waist.


If your in a more powder prone state, may be 95-108mm.


I've been on the Volkl Kendo for the last 5 seasons here in Vermont, USA. I have fatter skis, but 90% of my time is on the Kendo.

There is no exact definition. Just as there is no definition of a small car vs medium car vs large car. Theres some idea but they blur.

You can collect and aggregate tthe top buying guides for "all mountain ski" lists made by the industry (e.g. magazines review site) for this year or last year.

Then after you've read all the top lists, just grab onto the descriptions they use, or pick the top skis, then use the description of that particular ski from that manufacturer.

No single description is available, but you can get an averaged description.

You're Swiss, you can relate:  it's the Swiss Army Knife of skis.


It's a general utility tool for skiing all of the mountain in all conditions on one ski.  It may not be the perfect tool for a specific condition and/or terrain but it is the perfect tool for all conditions and/or terrain.


As a poster above eluded to: the conditions you ski most should dictate if you err more on the side (width; rocker, side cut; taper) of soft snow biased or hard snow biased.

A ski that performs well on groomed slopes, moguls, and fresh snow. So you need to test them in all three conditions. Hope the weather cooperates.

Agree with Oldgoat. For me it comes down to dimensions, summarised by waist width. < 80mm = frontside carver/race/moguel. 80mm < < 100mm = all mountain. 100mm+ = powder

As for radius and stiffness…


I've never seen a manufacturer or retailer use any empirical measure of stiffness. Internally, I'm sure manufacturers pay very close attention to flex (essentially the inverse of stiffness), but there isn't going to be just one measure for a ski. Every part of a ski will flex a little differently, producing an overall flex profile or behavior for the ski as a whole.


I would assume radius is something determined while designing a ski, not measured after creating it. The radius is determined by the sidecut, and the sidecut needs to produce more or less smooth arcs when flexed on the snow. The overall sidecut shape would need to be designed in combination with the ski's other properties to create the desired behavior (primarily edge hold and turn radius) on the snow.

The trouble with using dimensions is that it's a moving target. A ski that was all mountain 10 years ago would be a frontside ski today. Also, some 105ish skis handle all conditions well, will others--softer with more rocker--are powder specialty. Obviously different all mountain skis favor one condition over others but all should be at least decent on all three. For the purposes of the OP it should be simple--most manufacturers web site ski sections have an all mountain category filter. Pick a couple of those. The key is that the OP has to test his ski in all three conditions against the commercial skis.


Good luck with your project. 

Tell us more about your ski if you have a chance. (Or maybe you'd better patent it before divulging the details:))

Thanks Guys ;)


Can I say that an All-Mountain-Ski should be able to perform on the slope, off slope as well as in the freestyle parc? 

I want to test it with experts which have to do all three parts I named before. Do u think that I can use this for my work at school? I have to write a final thesis and I am going to test my ski and compare it with two Rossignol all-mountain-skis. Now I have to write a questionnaire and I am not sure what I should ask about the skis. I find it very difficult to create some acceptable questions which are mostly easy to answer. Have you guys an idea? Would be great. Thanks

I've seen some twin-tip park skis mentioned as also good for all-mountain use (Armada AR7), but never a typical all-mountain ski (Rossignol Experience 80-88, Volkyl Kendo, Blizzard Brahma are top sellers) recommended for the park.
