Question about Shimano GRX RD-RX820
Hello ! Is it possible to use this derailleur with shimano 105 shifters and front derailleur? More specifically, R7120 105 STI shifters and a R7100 105 50-34T front derailleur.
I forwarded your enquiry directly to our supplier, who was able to confirm the following: "The GRX derailleur is compatible with the 105 12-speed components."
