I've seen plenty of data on wheels and helmets showing this is not so, but no data showing it is. With the only exception being those studies which considered only the unrealistic 0 yaw condition. Do you have a reference for a study showing data where aero helmets reduce drag more than a set of aero wheels over a range of yaw angles or even one realistic value?
