So I'm tearing down an old mountain bike to paint and simply build back up when the fixie itch just hit me. I already have to replace the crankset because the teeth are worn down like crazy. IF I replace the crankset and put on a flip-flop hub in the back, is that all I need to do to enter into the fixie world? I'd want to switch from the 26" rims to 700c rims for less resistence. If I'm going to do it, I want to ensure I'm doing it right. That's why I thought I'd call upon the bikesperts!!! Thanks guys/gals.
