Folks! Don't copy Alex's aero position. A few months on clip on aero bars made me a believer. Unfortunately a reckless cyclist ended those days. No aero bars involved in that one. At 63, I'll at least use the drops and coast in a turtled mode a few seconds downhill. Lycra is mandatory. Hey, my '79 Dave Moulton has non aero exposed brake cables, but the rider is just about the whole show.
