    what is the difference between XTR 952 and XTR 960 upper derailleur pulleys? besides the the little bulges and hollows in the plastic
    960 is much cheaper, does it not have ceramic bushing?

    I think one without the holes is the older styles the one with the holes is newer.

    I have run both, didn't bother to look inside the one with the holes yet, but..

    It slides more side to side on the bearing, kinda of more forgiving than the older style???

    Both worked well for me.
