In the really small sizes (like mine and Bluetree's) its pretty difficult to get a really aggressive position period - if you want to keep the bigger wheels you are kind of limited (and even with 650's its only marginally better) as to how low you can get the handlebars, because you can only make the head tube so short....... On most (probably all?!) of my bikes the down tube and the top tube pretty much meet, so its not like I could get those bars down futher. A Terry style bike with differently sized wheels would make it possible to get lower, but wouldn't be legal for races. I've given myself a little more drop by putting an angled stem on.
