dabac, thanks for the nice (and civil!) explanation of your experience and for the description. As I mentioned, I think the design you describe could have advantages: the cap and stem could come off without loosening the quill.

But you might want to check BBB's adapters.
The picture I posted gives one an idea: it's about 5.8 inches (a bit less than 15cm) long.

Increased rigidity is one of the claimed advantages of threadless stems/steerers.
They're probably all made towards the same fit. Don't think there's any way of promising a tighter fit.
You might try shimming yours.
I think a longer one would give me more length in the steerer tube and any wiggle would be minimized. A shim could work, but Id have to figure out how to ensure it didn't shift. I think that the best solution may be to put in a threadless fork and use a 1 to 1-1/8 step shim to use my current stem on the 1 inch steerer. Thanks again.
