When you look at old bikes, you begin to realize that much of the technology changed because riding styles changed, and on the other hand, riding styles changed because technology changed.

For example, in 1951, a 51-14 was considered enough to win Tour de France sprints. Riders rarely had whole teams leading them out, and most of all, they often sprinted in the saddle, turning the cranks at 180 rpm or more.

When I tested the 1957 Cinelli Supercorsa, I had to think of this. With a tread (Q factor) of only 120 mm, the bike really wanted me to spin.

Try that riding style on a modern bike, and you will wonder "How did they do it." Take the 1957 Cinelli to a modern race, and sprint out of the saddle, and you'll be left behind.

Narrow handlebars are another case in point. They work well with low trail geometries, because you don't need leverage to wrestle with the wheel flop. (Wheel flop is proportional to trail.) Put a wide handlebar on a 1950s bike, and you'll find it sluggish and odd - we tested a bike set up like that. Put the narrow bars on a modern bike, and it'll be hard to control. (It's not surprising that 42 cm and wider handlebars in the old styles are so rare. They were available, but few riders used them, because they did not work well with the bikes.)

Tire size plays into it, too. The old geometries don't work well with skinny tires, and modern geometries aren't ideal with fat tires... but that is getting away from riding styles and the original question.
