Headset query here. Tried fitting my 1" threaded headset at the weekend and found that, once I'd pressed the cup into place, it just slid right back out when I loosened the press. Turns out there's 0.3mm difference between the diameter of the old cups (30.1mm) and the new (29.8mm). That's clearly not enough for the headset to be the wrong size (i.e. it's not a 1 1/8 inch instead), but obviously it's not ideal. What can I do? Loctite?
For reference, the frame is an old Ciocc San Cristobal. I've heard the issue might be due to a slight difference between ISO and JIS, but given I'm even asking that question, it should tell you how little I know about this.
Cheers.
