Dura Ace headset crown race
I have an old 1985 (but beautiful) Dura Ace 7400 headset which is minus the crown race. It is for a threaded 1" oldskool fork. Does anybody know what I can use to replace the crown race? I called Shimano and they said there were no interchangable parts. Does anybody have an idea about what I should look for regarding the replacement crown race?
Thanks.
