I've got an old Schwinn, according to the serial # a 1972, cantilever frame type cruiser. the bike was left out exposed to salt water air and badly rusted covered with house paint and generally falling apart. The frame is okay though. I am slowly bringing it back to life. I don't trust the fork, and even if I did it's threads were destroyed by rust. I want to put a new modern type fork on it but I don't know if I can do this. The frame will take a BMX size head set... but how can I put a MTB fork w/canti brakes on here?? Specifically will a 1" mountian bike fork fit in a 1" BMX headset?? Thanks.
