FC-M780(what i have) is the triple crank version
FC-M785 is the double crank version
will it be a problem if i changed my current outer ring 42T to a 38T outer ring of a FC-M785.?
shimano documentation on the FC-M785 shows that there are 2 38T rings.
Y1ML98040 Chainring 38T-AM
Y1ML98020 Chainring 38T-AK
and the FC-M780 Chainrings are -AE's.. so are they not compatible?
which one should i be getting or if im even in the right frame of thought that the M785 38T chainring is compatible with my current M780 setup.
OR is there a better option that i should take like other mfgs. like RF, TRUVATIV..
what i have right now 42/32/24 - 11/36
