Thought I would post a few problems I had using Shimano GRX Di2 rear derailleur. The first 2 photos show the interference of the derailleur and chain stay when the B-screw is set for correct cassette clearance. I was able to adjust the b-screw and get it to work but the cassette clearance is too far. I did visit my local shop and the Di2 tech redid the set up with the same issue. His comment was it'll work go and ride it, but if a longer hanger is available, it'll work better.

Great support from the shop (Trail Bike in Courtenay BC) which is mostly a mountain bike shop. Full disclosure I did buy a couple of bikes from them in my DF days. Bringing in the V20 did get all the techs and sales guys out for a look.

West Coast monsoons hve set in and XC skiing will start soon so the V20 is headed for a winter on the trainer.

Sounds like a good use case for the Wolftooth Roadlink

Yes I will try it. By the way the Rotor Q rings 48-33 seem to shift OK.
