Abstract: A snow ski having adjustable camber-flattening resistance and characterized by a flat ski body having opposing side surfaces defining insert-receiving voids extending along the body mid-portion, and elongate body-stiffening inserts removably secured within the voids and providing with the body a particular camber-flattening resistance. A method for providing a ski having a desired camber-flattening resistance characterized by providing a flat ski body with the aforementioned voids defined in the side surfaces thereof, providing an array of inserts having differing stiffness characteristics but each being dimensioned for insertion in the voids, selecting a pair of inserts from the array, and securing such inserts in the voids. Preferred embodiments include inserts which may be used in one of two orientations to provide differing camber-flattening resistances.
