"When used in combination with a road bike in touring position (with the hands on the handlebar), a partial fairing brings the power required to overcome air resistance at 35 km/h down to 157 watts. This compares to 220 watts for an unfaired road bike in touring position, and to 176 watts for an unfaired road bike in (a much less comfortable) crouched position and wearing tight clothing. A partial fairing on a road bike thus offers a similar advantage to that of an unfaired recumbent (148 watts). With a headwind, the advantage of improved aerodynamics becomes even larger."
