The Uno 21.1mm quill stem adapter allows you to fit a threadless stem to a traditional threaded fork and headset. Its aluminum alloy construction offers a way to update your bike's cockpit while retaining its threaded fork system. Choose from black or chrome finishes to suit your build.
Compatibility note: The original listing also references 1-1/8-inch stems and handlebars with 25.4mm or 31.8mm clamp diameters. This differs from the listed 25.4mm / 1-inch stem-clamp specification above. Confirm the adapter's external stem-clamp diameter and select a stem with the correct handlebar clamp size before ordering.

With an old Schwinn you are very limited as to what stem, handlebars you can put on it. This little accessory opens it all up. I can use any of the new stuff out there!
I had a hard time finding options to get better riding position on my old bike with a 21.1 mm stem. This allowed me to use a riser and some handlebars I had on hand.
Fantastic, I've looked everywhere for this and finally found it here. Beautiful piece and fast delivery. I will definitely order from SGV bicycles again
This quill for the quirky sizing on my Schwinn Le Tour '85 . . . worked out great!
This saved my old bike from the landfill. Yay!
