Smoothie,
You're absolutely correct, but you seem to have missed my point - it wasn't that you can be fatter and catch skinny guys if you have aerowheels. IT was that a guy spinning his 39 with aero wheels isn't going to beat a guy who can push the 53. So, be the guy who can push the 53. It might also help to have some aero wheels.
