Monster, Monsteur, Monstour , 26/29+ and Expedition and Adventure bikes

Doing a bit of research into a hypothetical monstercross build, it seems like the new sram gx group could open up some interesting possibilities. So long as they stick to 1:1 cable actuation, it should all work with their new cx1 shifters, making a 1x11, hydro braked build possible. Ignoring what I said about back-woods serviceability, that's would make for a pretty awesome bike!

Edit: further research says they won't play... Different ratios, buuuut, there's a lot of info on various hacks here the gist being that you can use a 10sp MTB derailleur as long as it's non-clutch/ dynasys. Or this:

Boo cycles claims at NAHBS that: "Another cool thing they figured out with this build was that you can hack XX1 rear derailleurs to work with CX1 drop bar shifters... they found you could determine the pull ratio by putting the CX1’s derailleur cable loop and mounting it on an XX1 rear derailleur. By swapping that piece (the black plastic bit that the cable wraps around between the adjustment bezel and the derailleur’s pinch bolt), you get the XX1′s bigger pulley offsets with CX1 shifter compatibility."
