you need to be a bit more specific about a 'Lousy Bike" and Commuter bike. I see what some gents on here call commuters and they are nicer than some of my good bikes.

there are also some riders whose race bike is their commuter. also back when index DT shifters were the hot new thing, one of the best riders on our shop team rode a 2 or 3 year old Pinirello with modolo brake calipers, shimano aero levers, SR crank, campi derailleurs, friction shifters and mismatched wheels. he also rode this to class and anywhere he did not want to walk including the 20+ miles to and from the weekly training race. was his bike "lousy" compared to the rich freds with topshelf dura ace rides?
