Yeah, I saw Sheldon's site too, but as I said, I saw someone that indicated that it was only a specific type of AVA stem...
Given two opinions, I lean real heavily toward accepting Sheldon's over an anonymous person's. However, even though he is a great source, I do think Sheldon has the potential to be imperfect.
For safety, I think a blanket statement doesn't hurt, but with the increasing shortage of French sized stems, I would hate to toss one out that is OK.
There is always the factor that 22.0 can be acheived easily by sanding a 22.2 stem... That and I do need to start getting rid of parts that I'll never use.
Anyone want an AVA stem and alloy bar? If the non-Sheldon site I read is valid, it isn't the death stem.
