Shimano's brifters go ka-thunk, over a chainring, and you cope with the chain angle changing
as it moves from low to high.
no fine tuning after the shift . so some scraping of chain against the wider may result.
the shape of the cage tries to reduce this...
so I am glad I don't use them, myself, on my own bikes.
Do my coping on OP's bikes, in the shop.
lots of Mountain FD, now are fitting the cable anchor below .
a PIA to fuss with..
Old school, I prefer the cable bolt above the Pivot and cage..
