Abstract
The object of the invention is a free technique ski pole comprising a pole stick (2), to the lower end of which is rigidly fixed by sleeve-like fitting (5) a plastic snow disc (3), near the front edge (8, 9) of which is a spike-fastening sleeve (6) to which the spike (7) is fastened. In free technique skiing the pole is in a sideways inclined position during pushing. The spike's hold is thus improved and the support of the snow disc's bearing surface on the ground becomes more even, when looking from the front, the direction of the longitudinal axis of the pole stick forms an angle of about 5.degree.-15.degree. with respect to the direction of the spike (7). Correspondingly, the snow disc edge (10) on the side of the skier is positioned higher and the bearing surface (12) connected to it forms a smaller angle with respect to the horizontal plane than the outer side edge (11) of the snow disc and the bearing surface (13) connected to it.
