Single biggest aero/speed gain you can buy, followed by your kit. My fitness has improved considerably over the last year, and I still can't touch my lap times on our local TT loop that I did last year with clip-on aero bars.
Wheels actually provide fairly small gains, but they look cool and we like them.
