Give me a break! :madman: Replaced my chain and cassette and predictably enough, my middle ring needed replacement as well. Went to the LBS and got a new one- cardboard says XT, 104 bolt circle, 32 tooth... all OK right? Get it home and found Shimano changed the size of the tabs on the rings- the 760 won't fit my 750 arms. The rest of the stamping looks identical. Why do they have to pull this BS?? I'd rather have a Race Face ring, but if Shimano has to change things every generation for no reason, who knows what will fit. :madmax: Off to look for another somewhere...
