Ok finally got it home and excited to build! I was disassembling to clean frame and fork and the lower head tube race of the headset came out in my hand. On further inspection the race was spinning in the head tube such that it wore a groove in the head tube and now it’s under spec so won’t hold race.
I will have to replace headset as it’s worn (see crown race) but
1) how to retain head tube race such that it’s centered properly and can be removed later if necessary? I don’t want to use epoxy or equivalent.
2) replacement for TDC Continental Italia? Hard to find stack height in internet. Some say 38.5 others 41mm
