I was afraid of that too, not sure if a new collar would work, either. I've been eyeing a new Campy collar and may try that out.

Yeah, 31.0mm is weird. I don't know why they didn't just make it 30.9mm but some boutique builders seem to relish their "non-standardness"

I may ask around my club to see if anyone has a spare 31.0mm to test out before I drop coin on a new one.

'Nother question... how can I tell if it would work? .1mm is less than the width of a human hair. Can something "appear" to be on tight enough then slip once you're 50 miles from home? Can a torque wrench give you the most accurate reading?
