like others, aesthetics matter to me in that i like to ride a nice looking bike, but when function calls, i'll gladly do something aesthetically stupid like putting some clip-on aerobars on a hybrid. form follows function.
plus, putting aerobars on a hybrid pisses off the purists, so that's good. those people need to be prodded as often as possible.
it's certainly goofy looking, but it helps make the bike "mine".
