Stem size on a '84 Trek (it won't fit!)
 

Ok, I'm puzzled. According to vintagetrek.com my 1984 trek 560 needs a standard 22.2 quill stem. The question is, why won't my cinelli oyster fit? It's just too big.
Here's a link to the oyster: http://www.peterwhitecycles.com/stems.asp
By the way, the stem i'm interested in replacing is the stock SR that came with the bike.

Um, yea, i'm in idiot, so nevermind. Don't try to do bike maintenance at 1am. Lesson learned.

What did you do, forget to loosen the expander bolt? :o
