I thought you had to use an xtr derailleur to get rear only function?

I’d like to see completely interchangeable function between 9100 and 9200. It should be possible to use a 9200 rear on an 11 cassette.

To get RD only on a Di2 system all you need to do is not fit a front derailleur.

If you want to, the shifter buttons can be remapped to your heart's content using the standard eTube software.

That's what I thought - because they sell the single button shifters, it can't be that tricky. My TT bike doesn't have a FD but I left the normal shifter and cable in place in case I decide to go back to 2x.
