ABSTRACT:
A sled having a frame supporting front and rear pairs of skis. The front portion of each front ski is pivotally mounted at the bottom of a front strut so that it can tilt about its longitudinal axis and can pivot about the axis of the front strut. The rear portion is mounted for pivotal rotation about a rear strut which is affixed to a strut support that pivots about an axis that is parallel to the longitudinal axis of the sled. During turning, the rear struts swing opposite to the direction of the turn, thereby causing the front skis to tilt and bite into the snow. The rear skis are tied to the front skis so that they also swing out and bite into the snow during turns.
