I also posted this in the mechanics forum but perhaps you can help too...
I recently received a 1979 Falcon. The frame is Reynolds 531 and is in relatively good condition. It was originally a 10 speed with a Campy Velox group.
I want to rebuild it into a single speed/fixed gear with a flip flop hub but I don't seem to understand the part about hub sizing. I measured the rear drop outs and got 102 mm. Is this correct? That doesn't seem like an available size for fixed gear/single speed hubs.
Can anyone help shed some light on this for me? I just want to make sure I am measuring it correctly before I order any parts.
Pictures to follow...
