headset issue- lower head tube cup is loose.
Loose as in I can push it in and pull it out with my fingers and it can spin even(with effort from me twisting) when the fork and headset are fully assembled.
The headset measurements match the head tube dimensions. I had another headset in this frame and it fit well, so I am guessing the new headset is ever so slightly off.
The new headset is a new Tange Passage model measuring 30/27 and the bike is an '88 Schwinn Premis.
So the frame and fork should be JIS, the old headset that fit well is JIS 30/27, and there is a slight bit of space...odd.
Is the head tube really 30.2 ISO and I stumbled into getting the other headset to fit?...that cant be right, right?
Some loctite on the cup and call it good?
***I just measured the original white Tange Levin CD headset that came with the bike and the lower cup is 30.08 so thats another data point.
