I can see your point. Though the fact is that *mine* are incompatible, so I think the word is correctly used. I acknowledge that someone might interpret that as meaning they are known to be uniformly incompatible. But that's a reach without reading the thread, where I definitely speak only of mine.
I haven't tried other samples of either. I can't say I intend to do so (just as expensive for me as it would be for anybody reading this). But if someone else is using a VO Grand Cru 107mm BB with an RBW- purchased XD2 triple crankset, I'd love to hear about it of course. Even better would be if someone were to purchase a VO Grand Cru 107mm BB and XD2 crankset tomorrow and make them work. Either situation would support the notion that one of my parts is not-quite-right.
