Single-track roller skate comprising at least three wheels which are disposed one behind the other and the rolling faces of which comprise in the cross-section substantially identical curvatures, wherein at least one front and/or rear wheel comprises at least in portions a comparatively different degree of elasticity than at least one central wheel. The rolling faces of the wheels comprise preferably a flat or slightly curved central portion and on both sides of this central portion in each case a more greatly curved running shoulder portion, wherein each running shoulder portion of the front and/or rear wheel comprises a comparatively higher degree of elasticity than that of the central wheel. In a convenient manner the tire body, forming the rolling face, of a front and/or rear wheel can be manufactured from a material having a lower Shore hardness than the wheel body of a central wheel. |
