Yeah I figured as much. I have a triple where the 26T innner shifts into the 42T middle ring and that can be slow at times but I attribute that to the low chain tension. I can always throw on a smaller outer ring. Maybe even one of the pinned and ramped ones by Velo Orange.
I do know a 20T difference is a lot. Most derailleurs have a maximum of 16T. But I do believe a better shaped cage might help here. A 2x11
Shimano Ultegra FD-R8000 has a narrower and more shaped cage with some extra guides on the inside. I could drop down to a 44/28T and still have a fairly good gear range of 457% or
24.3 to 111 gear inches.
did something similar but he uses a 46/30T chainring so it's within spec.
