Camber/Rocker
This refers to the profile of the ski when viewed side-on. Camber is the upward curve that’s usually built into the middle section of the ski. When compressed, it provides the ski with edge hold and power. Rocker is the upward curve of a ski that is used to increase float and improve turn initiation. The market is awash with many different camber/rocker profiles depending on the kind of snow, terrain and user the ski is aimed at.
Carbon
Carbon is often used as an ingredient in the construction of high-end skis. It usually reduces the overall weight of the ski versus other materials and provides a damp and reactive ride.
Radius/Sidecut
A ski’s sidecut is the difference between the tip/tail and waist widths. The narrower a ski’s waist is in relation to its tip and tail, the deeper its sidecut. This will result in a smaller (tighter) turn radius. The wider a ski’s waist is the longer its sidecut and bigger its turn radius. Skis with a big radius will make naturally longer turns. They tend to be more stable at high speeds though are less able to make tight turns.
