A regular road bike, so to say, will have room for tires larger than 23mm, a longer wheel base, fender and/or rack mounts. A Schwinn World Sport is one of those. Findng something like a Centurion Dave Scott Iron Man would be a high end production 80's bike without any of those accomodations.
The question is what do you really want out of your bike? Nice light and fast are rarely practical everyday bikes. People do it all the time but how much are you willing to deal with a bike that doesn't work for you much beyond being a light set of wheels.
