A pair of substantially rigid rectilinear members that are stiff in torsion, are attached to the top of the ski by pivoted mounts that are rigidly secured to the ski. Two mounts lie to the rear of the ski's binding area, and two mounts lie in front of the binding area. The rigid members are mounted longitudinally of the ski, and the pivoting is transverse thereto. One mount of each pair of mounts is directly pivoted to its rigid member, while the other mount has an intermediate member pivoted transversely to the ski and also transversely pivoted at a point spaced therefrom to its rigid member. | |
