I used to love my upright roadsters just as much as I love the more aggressive mountain bikes and even more aggressive set up on my road bike... until I fragged by lower back.
Whereas I could and did take 80-100 mile rides on bikes like my old Raleigh Superbe I cannot ride in this position for very far at all and my bikes (for the most part) have a French fit with a relatively neutral saddle to bar drop to keep me in a comfortable forward riding position when I am on the hoods and still let me get low in the drops.
