Abstract
A wheel including a rim, hub and at least one spoke, is disclosed. The spoke of the wheel has a leading edge with an aerodynamic protrusion and a valley. Also disclosed is a method of reducing aerodynamic drag on a wheel. According to the method, airflow around an aerodynamic protrusion disposed on a leading edge of a spoke of the wheel is disrupted into a plurality of airflows forming a first vortex about a first valley associated with the protrusion and a second vortex about a second valley associated with the protrusion. The plurality of airflows are joined at the trailing edge of the spoke.
