I'm running Ultegra Di2 with 11/36 cassette and am thinking of going with Absolute Black subcompact rings for bikepacking. If I could cram a 42 sprocket on the wheel as well, that would be in the sub 20 gear inches. Sweet!

Please let us know.

Perhaps I shouldn't have said full ultegra. Cassette is XT M8000 11-42. I seen plenty of reports where people were successfully running XT 11-40 without wolftooth link with medium cage derailleur and since I wanted to match gears to my hardtail I purchased 11-42 cassette with wolftooth DM link which is specifically designed for ultegra R8000 and dura ace 9100. Turns out didn't need it. 46-30 Absolute Black chainrings and XT 11-42 cassette with RX805 RD work together as a champ. Please note DI2 doesn't let you shift below 15T sprocket when on small chainring, with mechanical setup chain slap would be an issue. I used full length of new ultegra chain (116 links)
