Are PF bottom brackets really such a plague upon the cycling landscape? I mean, just about every one knows someone who knows someone who had a creaking PF BB, but is there any empiric data showing how often it occurs? Not trying to foment controversy, but it seems to me that throwing a large array of bikes our of consideration over BB design is a bit shortsighted. Especially when a simple, < $100 adapter solves the problem. Just sayin'
