I think my LBS would not like folks to post links to bikecalculator.com. In all seriousness though, this is a really interesting/eyeopening tool. As a 6'3" tall lanky guy, one of my many known racing problems that I have is getting my head / torso combo out of the wind effectively. I just never knew how much of a difference in MPH riding in the drops vs. on the hoods makes. This calculator clearly shows that instead of bike upgrades, I need to get to working on my position on the bike.
Is there any other advice and/or websites someone could recommend for getting someones body into a more aero in the drop position, other than getting forearms parallel to the ground / elbows 90 degrees, flatten the back as much as possible, and to relax the shoulders?
