I've put about 1700 miles on my XTR setup. Got ~1500 miles out of the chain which is a big improvement over the M8000 XT chain for me. I would only get about 800 miles out of those. This chain swap was done in time with my rear cassette and Blackspire oval chain ring still having plenty of life in them. I have no creaking coming from the cranks-chain ring interface. The only creaking I had was when I was running the rear cassette without the thin clear plastic spacer.
The brakes have been fantastic for me as well. I also swapped out the brake pads recently and got closer to about 1800 miles out of those. I did run them a little longer then I should have but my at home cleaning and bleeding of those calipers were fine to get them back to top notch braking again.
Cheers, Mike
