The road and GRX FDs can work with the 16T difference, but AFAIK the pull ratio is different and wont play nice with my XT shifters which I'd like to keep. Are there any options I'm not aware of? Thanks.
gonna need more info...

make/model/year of bike involved for a start... pull direction, seat tube diameter,.and a few other details will be needed.
