The invention relates to a ski equipped with a beam and a device intended to modify the stiffness and/or shock absorption of vibrations. The ski includes (1) at least one elongated element oriented longitudinally with respect to the ski, connected to the ski by a rigid linkage and which includes at least one free end, suited to be displaced longitudinally with respect to the ski when the ski is biased in flexion, and spaced longitudinally from the rigid linkage, and (2) a resistance device connected to the ski that cooperates with the free end in order to resist its displacement, the resistance force of the resistance device that resists the displacement of the free end decreasing between a minimum displacement position and a maximum displacement position. Such a ski maintains its stable qualities in a horizontal position and improves its pivoting and steering characteristics during tight turns.

A ski including a beam and a device for at lease one of modifying stiffness and shock absorption of vibrations, said ski comprising: at least one elongated element positioned longitudinally with respect to the ski, said elongated element having at least one free end portion, said free end portion being longitudinally displaceable with respect to the ski in response to flexion of the ski from a resting position to a maximum flexed position; means for rigidly affixing a further portion of said elongated element to the ski, said further portion of said elongated element being spaced from said free end portion of said elongated element; a resistance device affixed to the ski, said resistance device having a structure that is operatively connected to said free end portion of said elongated element to resist longitudinal displacement of said free end portion of said elongated element with respect to the ski, by producing a resisting force of a predeterminate magnitude during flexion of the ski from said resting position, and a resisting force of a magnitude less than said predeterminate magnitude during flexion at said maximum flexed position of the ski, regardless of the direction of said longitudinal displacement of said elongated element with respect to the ski, said structure including a friction surface that engages said free end portion of said elongated element.
