i want to get a cheap cheap cheap "road" bike off buysell or something to just get exercise on in the spring. since i live near farmlands i wanted to just pedal around the backroads and stuff. that means i don't need a tour de france perfect bike, and i really don't want something that is an "investment".
basically a cheap used commuter.
whats good to look for in terms of sizing etc?
i'm 6'1
