|WANTED: 21.15mm diameter stem for old mt bike!||girchygirchy|
Oct 15, 2003 5:33 PM
I'm looking for a 21.15mm (.833" according to the stem) diameter stem to fit my '84 Mongoose with a 1" threaded fork. I went with some people's advice on this board when I asked about finding a strange-sized handlebar, and was told it'd be easier to find a new stem. Well, apparently not.
I received my 1" threaded Ritchey stem from Nashbar today, and was surprised when it wouldn't fit...a quick check of Sheldon Brown's 'site showed me I have a size that was used on early mt bikes and other American bikes. The stems are a tiny bit smaller than the usual 22.2mm size, because of thicker steerer tubes.
So, if anyone would happen to have a 21.15/.833 stem lying around, and can't forsee it being used, please drop me a line. Thanks for any help!

|I'd be quite willing to accept an even trade also...the strange sized stem for my new Ritchey, which is useless to me. It's for a 'normal' 1" threaded fork, 140mm, silver.

|My first mountain bike was a Mongoose about that same year, and the stem was too short. I looked EVERYWHERE for a couple of years and never did find one. That size was on the way out by then, and the few I tracked down were department store junk.
I finally sold the bike and bought a Bridgestone, but if you're devoted to it, I wonder if you could swap forks for a standard 1-inch rigid one. There are still plenty of 22.2 stems out there. I never bothered to check the outside diameter of mine, so I don't know if it would work....

|I was faced with the same situation a while back (within the last year)...learned a lot in my search.
First, I'd check with your Local Bike Stores (LBSs). I found great things in their old parts "junk bin" (and the price was definitely right).
If you are unsucessful there, Harris Cyclery (Sheldon Brown) supposedly stocks some options. go to:
then click on "Older American bikes that use the 13/16" (21.15 mm) size-Click Here"
Lastly, inexpensive steel options are available at
you can run a search for "stem 21.1" and you'll find several choices. I bought a "pyramid" stem with a very long quill for my budget fixed-gear bike for <$10 including shipping.

|or odd for that matter. Nearly every junk Huffy/Murray ATB sitting around the LBS has an .833 stem. Or they can order part # 57007 from J&B Importers- it looks kinda like an old Suntour XC except cruder.|| |
