I know there's nothing in it between an XTR and XT rear mech when paired with XTR or XT levers.
But anyone have experience of X9 vs X0 rear mechs? I've currently got an X0, but I either need to get a chain device, or go for a Type 2 mech. And I'm not spending silly money on a new X0, but the X9 Type2 at £66 is pretty good value.
Anyone used both, with the same shifters and care to comment?
