Anyone have any suggestions for books, articles, etc dealing with aerodynamic cycling? I am thinking of making some home-built components that will either greatly improve my aerodynamics or (more likely) make me look like a total idiot during my training rides. Even on a tribike, I still feel like a cinder block with fighter jet wings. There has to be something to improve the overall aerodynamics of bike and rider.

Look up Time Trial bikes. You should find plenty.

The biggest improvement one can make in aerodynamics of bike and rider - is to get a high tech. ultra fit at a LBS that offers it. I had it done on my Ironman bike, and is well worth the time and money.

Chris Boardman has a good chapter on aerodynamics in his book (the complete book of cycling), and he was always one of the slickest riders around.
