Used DK stem for 1" threaded forks with a 21.0mm inside diameter.
The head measures 1-1/4" wide and 2-1/2" long. Quill and wedge measure 3-1/2".
Solid. In "as found" condition. Polish it up with your favorite product(s).
NOTE: I did clean most of the heavy crud off the quill, so it now looks better than in the pics.
Please make sure this stem's dimensions and measurements meet your needs; there are no returns.
