Thanks.

No, I agree. The bb is suppa smooth. But I'm warry because I've heard other people rumbling about these bottom brackets. In any case, I know it's not gonna last forever and I want to make sure I can replace it when it goes. 107, ISO isn't common. I guess that's the only problem with Miche Primato: compatability. Same goes for their track rings (a rare 135 bcd). The crank kicks ass but I don't want to be locked into their propriatary bb if there are better ones out there. But so far, the bb is running fine (4 months or so). I'll write again if I have any real problems with it.
