Not Shimano specific..
triples add a deeper pusher plate to deal with greater differences in chainring diameters, the mid to larger difference has to be 10t..
I have the same FD on 2 bikes , older over the BB shift cable routing requires a 52-42.. 26 , or the cable interferes with the bottom of the FD,
Under the BB riute I have a 50-40 ..24...
