If you have a threadless (clamp-on) stem and want to put it on your one inch threaded frame, this aluminum quill lets it happen.
Length: 130mm or 225mm. Diameter: 22.2mm.
Knurled top part of the quill that the threadless stem clamps to is 28.6mm (1-1/8") diameter and 42mm long. This is typical of clamp-on road and mountain stems, but is not a universal guarantee.
Max height line at 70mm from the bottom; abide by it.
