I am building a Single Speed commuter out of left over parts/free parts and all i need is a frame that takes a threaded fork and headset. I had a frame all ready to go, then i found out the head tube was some old random size that they dont make headsets for. Also it was in really bad condition. Where can i find a super cheap frame around 52cm size that takes a threaded headset? or should i just go to salvation army and get one of there old crappy mtb bikes and strip it for the frame?
