anyone know for sure that the grx 1x di2 specific rd (812 i think) will shift in a 2x configuration. looking to shift 50-34 or 48-31 x 11-40 better than i currently am with my ultegra rx di2 rd.
But you can do 11-40 with the Rx derailleur?
Yes. I have it running. Shimano say no but it works.
Rd 815 Also with road r8050 md cage. Both rated for 34t max.
