Abstract
A cross country ski has a bending resistance which is changeable with the help of at least one bending beam, the beam extending longitudinally of the ski and being arranged in the center of the ski. The bending beam is arranged loosely inside of the ski, symmetrically in relationship to a vertical longitudinal center plane of the ski, and is supported at its two ends on support surfaces of the body of the ski which extend approximately parallel to the running surface. In a first preferred embodiment, pressure can be applied to the beam on a side thereof which does not face the support surfaces by a pressure element which is supported on the body of the ski in the region of the upper side thereof. In a second preferred embodiment, the beam has on its side which does not face the support surfaces a pressure-transmitting member, to which a pressure toward the beam can be applied by a control mechanism.
