How To Convert Quill Stem To Threadless Stem With Adapter On Vintage Bike

Posted by on in Handlebars & Stems


I show how to remove an old quill stem and install a threadless stem with a threadless stem adapter. This is a circa 1990 Trek 1000. I’ve already upgraded/updated a bunch of stuff on this vintage bike.
Here is the threadless stem adapter I used:

BTW, the reason I cut the quill stem in this video was for ease and cost. I could have kept the stem, but I would have had to remove the handlebar tape on one side, remove the shifter/brake lever, remove the handlebars. And then later after reinstalling the handlebars, I would have had to remount the shifter/brake lever, and retape the handlebars. New tape would have cost $15-20. OR I could have just cut the old stem. So I chose to cut the old stem.
