Abstract: The present invention relates to a wheel for measuring distance for a ski, comprising drive means mounted for rotation at one end of an arm, the other end of this arm being mounted pivotally on an axle parallel to the axis of rotation of the wheel and carried by a first portion of a bracket; this first portion being connected to a second portion adapted to be fixed on the rear end of a ski in such a manner that the axis of rotation of the wheel will be perpendicular to the longitudinal axis of said ski; the wheel drives a counter and the arm is subjected to the action of a spring tending to pivot it about its axis so as to apply the wheel to the ground.
