Abstract

The invention relates to frames and wheels which provide a reduction in drag. In the present track bicycle, the right-hand lateral surface of the front wheel (4) is flat and is offset to the left of the vertical plane of symmetry of the bicycle. The left-hand lateral surface of the rear wheel (5) is undercut and is offset to the right of the vertical plane of symmetry. When a front wheel (4) is placed alongside the rear wheel (5) of the leading rider, the total length of a team of racers is reduced without detriment to the longitudinal symmetry of the team. The necessary safety clearance between the surfaces of a front and a rear wheel (4, 5) is achieved in that the rim and tyre of the front wheel are offset to the left of the centre of the front fork (2) and the rim and tyre of the rear wheel (5) are offset to the right of the centre of the rear fork. Alternatively, clearance can be achieved by means of offsetting the headset to the left of the vertical plane of symmetry, with the front rim and tyre in the centre of the front fork and the rear rim and tyre in the centre of the rear fork. This solution is intended to improve the overall aerodynamics of a team and make it easier to steer through the turns of a track.
