22.2 mm quill x threadless stem adapter?

rickn

Greetings:
Someone out there (other than Performance / Topo) must be making an
adapter that would adapt from 22.2 mm quill stem to a threadless (1-
1/8"?) threadless type stem. I have been to a bunch of websites and I am
surprised that none of the "big Name" stem manufacturers make this item.
Any suggestions?

Also, I have encountered claims of interchangeability between 22.2 mm
stems and 1 inch stems. According to my scale, 1 inch = 25.4 mm (not
22.2). I'll take a guess: Maybe "1 inch" tubing refers to the O.D and
would have and ID of 22.2 mm? But that is only a guess.
Please educate me . . . .
Thanks,
Rick

The 22.2mm refers to the diameter of the quill, the part that inserts into
the steer tube, not the size of the stem itself.

Profile, Zoom and Nitto all make adapters that will allow you to use a 1"
or 1-1/8" threadless stem on a threaded fork. They're called stem column
adapters.

Made by 3t, ITM, and Cinelli as far as I know.

A stem for a threaded 1" steerer is 22.2mm in diameter, or 7/8".

A stem for a threaded 1 1/8" steerer is 25.4mm in diameter, or 1".

Yes, this does cause confusion, particularly on eBay where some of the
sellers are insufficiently exact about what they're selling...and may
be clueless in their answers to questions about the item.
