Shimano GRX Di2, rear derailleur is the RX 817, Shimano says max teeth is 42, my cassette is a XT 11-46 and the derailleur works without any problem, no adapter mounted.
But maybe BELLE Cycles positioned the derailleur change a bit lower? I will ask him, he knew that we will use a 46 cassette, also he build several bikes before this one with the same setup.
Front ring is a 38.
