Abstract
An aerodynamic bicycle frame may include one or more elongate frame members having a rounded leading edge, a blunt trailing edge, and a plurality of vortex-generating channels formed at opposite corners of the trailing edge. Successive pairs of such channels may be spaced apart by a selected distance, such as a distance corresponding to a wavelength of the expected flow instability.
