Okay, I now have the GRX 11 sp FD and Shimano FD Mount adapter headed my way. That way I can mount the braze on FD to my seat tube.
You could ride it with the existing FD but the chain rub on the outer FD plate is quite annoying......not to mention all the watts I’d be losing pedaling!?!???
At least I tried using the R8000 FD.....
