"On a technie note M.I.T. did some wind tunnel tests and found that in terms of aerodynamics one's head and helmet is by far the most problematic area and that from a saving energy point of view you are more efficient with a £200 TT helmet and normal wheels than an normal helmet and a £5000 set of dimpled carbon disks."
if people just learned to ride on the drops more instead of holding onto the shiny bit of bare metal either side of the stem they would gain more efficiency than any aero rim/helmet could give them.
