Abstract
An apparatus for facilitating optimum adjustment of a cross-country ski, the bending resistance and/or arch of which can be adjusted, includes a sensor connected to a control circuit, and the control circuit is in turn connected to either a drive mechanism which automatically controls the adjustment of the ski or to an indicating device which visually indicates the necessary adjustment to be made manually. The control circuit monitors ski performance at a given adjustment for a predetermined interval, thereafter determines an appropriate adjustment, then monitors ski performance at the new adjustment for the predetermined interval, and so forth. A gearing mechanism powered manually or by an electric motor can be provided to effect the automatic adjustment of the ski in response to an output of the control circuit.
