Yeah, so looks like the DA FD won't change into the big ring. Something to do with a different offset on the GRX chainrings, right? Presume it's out of the realm of adjustment for the DA FD?
"Generally speaking, the only compatibility concern with GRX is the crankset/front derailleur. Because the chainrings on GRX is ~2mm further outboard than other Shimano cranks, you should pair GRX Cranks and FD. "

Anyone got a GRX Di2 FD they want rid of?
