Hi, does anyone have experience with following Di2 setup based on Shimano components:

Dura Ace Di2 road shifters R9000 series with Shimano XTR Di2 rear derailler. The question would be if this component mix will work an if it will work in a 1x11 setup. Plan is to use the regulat Di2 junction boxes and internal battery.

On the front we plan to use a 40 or 42 Wolftooth chainring an on the rear an 11-42 or 46 XT cassette.

Any tips or trics for such a conversion? My gravel bike currently runs a 1x11 SRAM system.

Di2 Dura-Ace and Ultegra will work with an XT/XTR rear derailleur, as long as there is not front derailleur. I like 2x so I haven't done this, but my buddy has his bike set up with with the component mix you're asking about. 

Cheers!

Greg, thanks for your reply. Are there any alterations needed in the e-tube programming or will it work just out of the box? Read somewhere that the battery needs to be of a certain software version but that is an easy update. What combination does your buddy exactly use? Cheers, Sander

Hey Sander, 
I'm not sure exactly on the need for any programming, but I assume its all in the e-tube software. My buddy is running either a 42 or a 44 up front, with the XTR 11-42 rear cassette. He's loving the 1x setup for gravel though, and if it weren't for that RX rear derailleur coming in the next month or so, I'd be switching as well. I can check with him on the programming when I get back, in the next week or so. 

Cheers!
Greg
