Aerodynamic bicycle frame

Abstract

There is provided a bicycle frame comprising a first tube; a second tube extending transversely from an upper region of the first tube; a third tube extending transversely and downwardly from a lower region of the first tube, and towards the same direction as the second tube; and a two-part tube joining the respective ends of the second and third tubes, the two-part tube having a straight upper part and a curved lower part, the straight upper part being substantially vertical and the curved lower part being curved longitudinally towards the first tube such as to conform to the curvature of a bicycle wheel. The upper part of the two-part tube is adapted to receive a post member therein, and a first and a second set of tubes extend at the respective ends the two-part tube and are each attached to drop.
