I have to wonder - wouldn't the wider diameter stays make for a stronger frame? I know that wouldn't be in direct relation to whether or not a BB shell width makes for a stronger setup, but I would think the stay diameter counts for something. Then again, when comparing my two hardtails (one uses 68, one uses 73), there's physically no difference in the stays. The only difference I see is the hardtail with 68mm shell, the stays are welded right up to the edge of the shell, whereas the other hardtail with the 73mm shell, the stays are not welded on the edge, and the shell itself has a bit of a lip on each side. Basically, I could sheer off a few mm on each side of the shell on the 73mm hardtail and not effect the welds.
