Means for mounting ski binding components onto a ski in such a manner as to permit flexing of the ski without varying the distance between the ski binding components. A rigid plate is mounted in spaced relation to an upper surface of the ski by means which permit at least one end of such plate to be longitudinally translatable with respect to said ski. Preferably one end of the plate is pivoted to the ski and the other end of the plate connected thereto through a slot and pin arrangement. Thus the shape of the plate remains uneffected by flexing of the ski. The boot engaging components of the ski binding are then mounted on said plate and remain at a constant distance from each other regardless of any flexing which may occur in the ski.
