Abstract
The bicycle may have a frame and a front fork. A cross section of the frame or the front fork may have an airfoil shape wherein a leading surface is sharper (i.e. less round) compared to prior art airfoil shaped bicycle front forks and bicycle frames. Additionally, a maximum thickness of the airfoil shape may be located more rearward compared to prior art airfoil shaped bicycle frames and bicycle front forks. This configuration provides for a reduction in drag for headwind speeds of about twenty (20) to thirty (30) miles per hour and headwind angles of plus or minus fifteen (15) degrees.
