Yeah, if you look at a lot of the pro-racer boys they're riding very small bikes for their size which does mean exactly what you say -- their torsos are much farther forward over their bars than the average rider. Of course, they also spend the entire race on the hoods and have the core strength to do that.

And these guys are about, what, less than 0.5% of the population?

And you also notice that it is the rare race that goes over 5 hours in the saddle.
