Ok, I pulled out my old quill and the outside diameter is 25.4 mm.

I'm wanting to put in a steer adaptor.

Will this work?

I'm confused because the outside diameter of the adaptor is 22.2 mm.

22.2 (7/8") is the long time standard quill diameter for 1" forks. If your current quill has a 25.4mm (1") OD then it's for a threaded 1-1/8" fork. There were a number of these made in the early days of mtb, before threadless became dominant.

If you need an adapter for to use a threadless stem on the same fork you need to find one with a 1" OD in the section that fits into the fork. (assuming you do, in fact, have a 1-1/8" threaded fork)

Your quill stem is made for a 1-1/8" steerer (ID= 25.4 mm, OD = 28.6 mm) which is apparently what's on the bike. Your steerer adapter is made for a 1" steerer (ID = 22.2 mm, OD = 25.4 mm) and it's the wrong one. You need to get an adapter made for a 1-1/8" steerer.

Nashbar offer them in both sizes: http://www.nashbar.com/bikes/Product_10053_10052_175545_-1_202918_10000_202442 The product description under "Features" described the differences.

Appreciate it HillRider, that's exactly what I was looking for.
