Abstract

An aerodynamic wheel, suitable for bicycles, which includes a central hub, a rim and a plurality of spoke members extending between the rim and the central hub, each spoke includes a leading edge and two trailing edges with air deflecting walls extending between each trailing edge and the leading edge. A cross sectional profile of each spoke about mid way between each end resembles a 'V' with a centrally located trailing edge cavity positioned between the air deflecting walls and behind the leading edge. The wheel and spokes are installed for rotation with the leading edge of each spoke forward so that as the wheel rotates the leading edge, air deflecting walls and centrally located trailing edge cavity create a drafting effect for the following spoke leading edge thereby reducing aerodynamic drag and effort required for rotating the wheel. The wheel may be designed with at least three spokes while the hub, rim and spokes may be manufactured as a single component or as separate components.
