I really don't know, but I would be surprised if it was after. The crack was on the outside of the seat stay and was running along the length of the stay, I wouldn't think it would need chopping and then joining again the seat stay which could have resulted in a wider spacing. I think it's just tolerances or even incorrect assembly (I bought it from a Salsa dealer in Missouri, the BB was installed incorrectly so not really sure if the dropouts needed to be shimmed already). But I don't really know.
