i just built my first fixed gear out of a early nineties gt mountain bike frame. i used a surly fixer hub. still have my triple crank on it with bramma handle bars and a fender. it looks extemely ghetto but is a blast. my first hill i almost blew out my knee when i forgot about the whole fixed thing. fixed riding kicks ass. i love it. i'll post some pics as soon as i find a digital camera and figure out how to post. anyone got pics of a ghetto fixie?
