This part installs into a 7/8" Internal Diameter tube (22.2mm) to convert your "old style" handlebar stem to a modern one. Older mountain bikes had those expanding style stems which limit your configurations and options for changing your bike around to fit you better or just to use modern components since there are FAR more options now. MAKE SURE you have a 7/8" tube on your bike... that's the most common size, but if you want to avoid a delay- measure it.
I converted two of my "vintage" bikes with these stem converters so I could install adjustable angle stems. With so many options on the market now, prices are great and you can replace those aging, ugly stems or make that old bike fit better- in my case, I needed to raise the bars since I'm getting a bit older and need a more upright riding position.
It's funny, the non-adjustable rusty Ritchey stem I replaced with this cost more than a new modern stem conversion, new adjustable stem AND new handlebars.
Keep those older bikes on the road, the "technology" hype they use to try to sell new ones is more marketing hype than real benefits the average rider could ever notice. Buy a used bike for $300 that originally sold for $3000 and ride in style. :)
