Camber profile

This page explores the rocker and camber types used by Exegi, and the rationale behind using the different types. There is an explanation of how and why different amounts and shapes of rocker features affect different performance parameters.

What is Camber?

Camber refers to the concavity of the base of the ski or board, in reference to the longitudinal axis. Typically it is described as its depth (or height), measured from the bottom of the base to the surface (snow), with the board or ski under no load.

A highly cambered ski would have something in the order of 10 mm of camber, and a highly cambered board would have around 7 mm of camber. A lightly cambered ski has about 3 mm of camber, and a lightly cambered board would be almost flat (under 2 mm of camber).

Generally speaking, and with all other things being equal, camber increases carving grip and increases rebound, making it harder to slip or pivot the board or skis. Powder riding gets increasingly “busy", and skis and boards will increase their tendency to hunt for the next turn at the release of pressure. On groomed snow carving performance is enhanced at the expense of ease.

What is Rocker?

Rocker is simply any base condition, longitudinally, where there is negative camber. A camber of zero is called flat. These measurements are again considered in an unweighted context.

Impact on Design

Exegi tries to match the rocker or camber profile to the individual customer, based on the desired performance characteristics. The ski or board and the desired performance envelope are closely tied to this feature. Further, the interaction of torsion and longitudinal flex, sidecut/tip tail geometry, length, and rocker profile are subtle and interrelated. It has to be worked out in the context of the whole picture of how the board or ski is intended to be utilized. This decisions are nailed down during the design consultation, prior to any work being done to build the board or skis.
