The tires came from Nashbar. As for the fork and head tube I have not put the whole thing together. I will try now and see. The head tube is not the same as most older balloon tire bikes. The headset is like an old British bike style. I can also shim it up if needed. I will send a closer pic of the headset and tube when the frame is finished. I put the seat together last night. The cover is had to get tight. There is still a few wrinkles in the top. This is the first time doing a seat. I will post pics later. Most of the work on this bike is the first time doing this. I have a great teacher and he shows me how to do it before I attempt it. Most of the work is simple though.
