And you write things like "INNER dimension of my headset/steerer tube hole is a lot nearer 1 1/8" than 1" -
If your headset - the bearings - has an 1 1/8" I.D - can take an 1 1/8" O.D steerer tube - then it's really a quite common size. An 1" quill stem would fit.
Well I looked high and low last night. I remember leaving them on the piano bench, and my son said he saw them there and put them on the computer chair... and there the trail goes cold. But you don't want to hear all that drama.
So you say "your headset - the bearings"; when I say 1 1/8" ID I mean the hole that the quill stem fits into, seems to me bearings are somewhere else, and I'm not sure how their diameter would relate (Sheldon Brown has separate columns in his cribsheet for crown race and frame cup)
But are you saying that quill stems have at least 1/8" of slop, so if a quill stem is 1/8" too small (1/16" gap all around), that's fine, the expansion bolt will still do its job?
