Fixed is markedly different than SS, where the lack of a freewheel pretty drastically alters the ride, both in feel and function.

While there is some utility to having narrow bars in the city, short/narrow bars are pretty much a fashion statement. The look was copied from bike messengers, who chopped their bars to better fit through traffic. But anyone who chops their bars narrower than their hips is sacrificing function over form (if the bars go through a space, the hips are going to have to fit through the same space).

Still, I'd rather see people using bikes as fashion statements than cars.
