I know nothing about campag.
I have this headset which is 1 1/8 and ahead.
It came on a period correct and built mtb from mid 90s.
From my research it’s a HS03.
But is it a OR - Off Road ? Ie a mountain bike headset.
This below link seems to suggest that 1 1/8 were only OR. Can anyone shed any light.
