Terms to Know
Full-cap, mustache rocker, stiff tail and a damp feel. Get your mind out of the gutter, weโre talking ski features. Here are the terms you need to know, broken down by shape, construction and feel.
Camber
The arch of the ski is its camber. Itโs most obvious when you place a ski on something flat. With a cambered ski, the tip and tail sit on the ground and the center is in the air. The higher the camber, the more power and bite a ski will have. Skis with no camber or even reverse camber (the center sits on the ground and the tip and tail are in the air) promote float and easy turning. These shapes are typically powder-specific.
Rocker
How much and how far the tip and tail rise above the snow. Also known as early rise. The more rocker, the easier a ski is to turn. Less rocker promotes better edge hold. The most common rocker profile is mustache rocker, tip and tail rocker with camber underfoot.
Turn Radius
A measure of a skiโs sidecut measured in meters. The shorter the turn radius, the tighter the turns the ski will want to make.
Sidecut
Directly related to turn radius. Sidecut is the profile of a ski from tip to waist to tail. Typically the arc is consistent across the skiโs length, but brands are playing with combining different arcs along a sidecut to add multiple turning behaviors to one ski.
Waist Width
A measure from edge to edge at the narrowest point on a ski in millimeters. Wider tends to float in fresh snow better, while narrower is easier to edge into hard snow.
Ski Construction
Flex
This refers to how easy it is to bend a ski. Manufacturers adjust the flex with the materials and construction. We break up a skiโs flex into three parts: tip, center and tail. Tip: A soft tip makes it easy to initiate a turn and absorbs bumps. A stiffer tip provides bite, great for hard snow carving, and stability at speed. Center: A soft center provides a forgiving ride thatโs easy to turn. A stiff center feels stable at speed, even if the tip and tail are soft. Tail: A soft tail feels loose and buttery. A stiff tail adds snap and pop at the exit of a turn. It also provides a good platform for landing jumps and skiing on uneven terrain.
Sidewall
The part of the ski above the edge and below the top sheet. The style of the sidewall plays a role in performance and durability. A full sidewall has vertical walls and is the toughest and most powerful. Cap construction slopes up to the top sheet and is easier to ski. Between the two are all kinds of hybrids.
Top Sheet
The top of the ski. Usually just a protective layer with graphics.
Base
The bottom of the ski is a hard plastic. There are a couple of hardnesses of base material, but in general, it all comes from one of two factories in Europe.
Feel
- Dampness: A skiโs ability to absorb vibrations. A damp ski is stable at speed and holds an edge through a carve.
- Playful: An ambiguous term generally associated with a loose tail and a snappy feel. The opposite of powerful, playful skis is happy to skid.
- Powerful: Like an expensive car, a powerful ski feels stable at high speeds and bites into hard snow. Harder to control, theyโre often stiffer and need more energy and skill to ski.
Mounting Types
System Ski
When a ski comes with a binding for a set price. The binding often integrates with the ski rather than mounting with screws.
Flat Ski
A ski that doesnโt come with a binding.
How to Know Itโs Time for a New Pair of Skis
Skis have a life, but figuring out when itโs over can be challenging. When you ski the same pair of sticks for a season or a couple of seasons, the changes are incremental. They donโt just stop working, so you may not notice right away. If you donโt tune your skis regularly, try an edge sharpen and wax before writing them off. A quality pair of skis should last at least 100 days of skiing.
Beyond age, there a few other signs itโs time to upgrade: a lot of cuts and scratches to the top sheet, side walls or base, especially if any penetrate into the core materials; skis that donโt feel like they have any spring or life to them; or if the skis wonโt do what you want them to. The last could be because the skis are toast or because youโre not as fit or sharp as you used to be.
โIf a skiโs not fun, finding the right pair means youโre going to enjoy the experience more,โ Rabinowitz says. โAnd if you havenโt bought a new pair in 10 years, then itโs definitely time. The technology has totally changed for the better.โ
