So I was just putting the finishing touches on my 74 Serotta. I took it off the stand and found the headset was very stiff. Back on the stand and fiddled around but couldn't get it right. I finally decided to take it completely apart and as I began disassembly, I found the problem was the top of the brake centerbolt was rubbing the edge of the lower head race.
Suggestions please?
