Shimano XTR RD-M9000 compatibilities w. Dura-Ace shifters

Hey there,

I'm looking to buy a gravel/cross bike with a Trek Crockett frame and a 1x drivetrain. I know very well that SRAM's 1x line-up might be the best or at least the most complete compared to Shimano. But... I like the grip and system of Shimano levers. This is just my personal opinion even though some may find it stupid and still recommend a SRAM built 8)

Now, I have the following questions: I can't quite figure out what derailleur I've seen on a crossbike ones, but it was defiantly a Shimano and with Dura Ace levers for a 1x drivetrain. It was a Di2 tough, which I'm not going with.
I've been looking at the components below. Are they compatible together?

– Dura Ace ST-R9120 STI (Levers)
– Dura Ace BR-R9170 (Flat-mount Disc Brakes)
– XTR RD-M9000-GS Shadow RD+ (Read Derailleur)

Or are people using some kind of hack to make the Shimano Ultegra RX RD800-GS Shadow RD fit the bigger cassette?

Hope you guys are able to help me and clear it for me :)

Thanks,
Alex
