Ah, so it is mechanical Ultegra 11spd shifters with the mechanical XTR 11spd (M9000) RD
There was a compatibility gap in the 10spd groups - road vs mtn due to a different dynasys throw ratio. That required one to use the 9spd mtn XTR RD with the 10spd road shifters. Now with the 11spd groups, throw ratios are back in synch.
I still can't get my brain wrapped around the fact that Shimano is not releasing any 11spd cassettes with 34t or 36t max cogs. You only get a 32t or a 40t cassette choice for big cogs
Regardless, it's neat to hear someone has already jumped on the super-sized cog setup.
