Following thread. I just did a lot of research into the GRX line but pulled back at the last minute for now. Just to much to swap from my exiting glob based on a traditional Shimano 2x10 setup with the original road pull ratios (Tiagra 4600 and similar). I would have had to do the whole GRX line of brifters, FD, RD, and cranks. I still got my 46/30 but did it just with chainring swap and some chain links. Maybe later..
