What riding stance do you prefer? (or maybe you prefer a mix)
More aggressive or Less aggressive?
Wide bars to open the chest or narrow for aerodynamics?
etc.

Personally I ride my modern bike with a slightly aggressive stance with the saddle only 2-3 inches above the bars and the bars the same width as my shoulders
However,
My vintage bike I ride with the saddle level to the bars actually placing the drops at the same height as the hoods on my modern bike. I prefer the comfort for casually riding with my wife who rides a hybrid.

I've seen a pretty radical range of sets ups on this site and would just like to hear a little bit more about them, why you choose the stance you have and what kind of riding you do (short rides, racing, long rides etc.)

I never new 3 years ago when I got into biking how many different ways you can fit a bike, I always assumed there was one right fit (how the shop set me up) and till recently when I started taking a real interest in biking (other than solo rides with no knowledge of the sport) I never questioned the set up.
