Aaron S.wrote a review of Shimano XTR/Dura-Ace CN-HG901 11-Speed Chain on June 15, 2016
I've had about a half dozen rides so far on my complete XT 1X11 set up, on mixed single-track, moderate downhill and serious climbs. So far I love it! I know it's not as light as the SRAM drivetrains, but the cost and simplicity of the drivetrain swap pays big time. No dropped chains, no mis-shifts. I'm really loving it. Coming from a 3X or 2X set up, I don't have the top-end road speed, but who cares! If you're thinking about upgrading, do it.
