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.

I don't get it. Why would you get the 1x RD if you're using 2x?

the pulley offsets and cage length should make it shift an 11-40 better. i can also use the garbaruk cage mod to make sure i have enough capacity.

@Netakure i have found it difficult to get the ultegra rx to shift it as well as i'd like.
