Convex curvature built into the length of a ski. Distributes the pressure of a skier's weight to the tip and tail, giving the ski more grip on the snow. › Dampening The reduction of the vibrations that occur when a ski is in motion. A damp ski is better able to hold an edge in the snow— but it might lack liveliness.
Tip, waist and tail widths: an expression of the shape of a ski.
A metal plank with a ski-shaped cavity milled into it. Typically, ski components (and liberal amounts of epoxy) are placed into the mold, which is then subjected to intense heat and pressure to bond the components and squeeze out excess epoxy.
A type of prefabricated laminate used to reinforce cores. Sheets of fiberglass fabric are impregnated with epoxy, cured and then cut to fit the ski's width and placed in the mold.
› Rocker (reverse camber)
The opposite of camber: The tip and tail curve up off the snow. Makes skis more buoyant in powder and easier to pivot on hardpack.
The narrowing of a ski at its waist; aids in turning when the ski is tipped on edge and pressured into an arc.
› Sidecut radius
A measurement, usually expressed in meters, of the depth of a ski's sidecut curvature.
The difference between the tip and tail widths. A ski with a smaller taper generally initiates arcs easily, resulting in a turnier ride, while a ski with a larger taper is less hooky and easier to skid.
The brand name of the aluminum alloy commonly used in laminates.
› Torsional rigidity
A ski's ability to resist twisting, often achieved by aligning glass fibers across the core at an angle (see "torsion box"). By increasing torsional rigidity, a manufacturer can make a lighter, metalfree ski that still holds an edge on hardpack.
