Abstract: An in-line skate which includes a plurality of wheels mounted to a frame each having a primary contact surface which contacts a skating surface to support the skater when the skate is in a generally upright position, and at least one secondary rotatable contact surface disposed at a level above the primary contact surfaces when the skate is in a generally upright position and positioned to contact the skating surface only when the in-line skate is inclined beyond a selected angle from the vertical. The length of the wheelbase formed by the secondary contact surface is shorter than the length of the wheelbase formed by the primary contact surfaces. By effectively changing the length of the wheelbase of the in-line skate when the in-line skate is at a certain angle from the vertical, a tighter turning radius may be achieved.
