11 Speed M7000 or M8000 medium cage work best.

Member your chain might be a bit short if changing from an older set up, so new chain would be a good idea.

It was you who posted a pic of mech stretched almost up to the chainstay wasn't it? yeah don't do that.

10spd shadow xt m785 works fine with a sunrace 42t on one of my bikes but on the other the same set up needs a wolf tooth extender thingy.

Worth the effort though. I've never ridden an 11spd but I've saved a bunch of cash not upgrading everything!

Edit - it's called a goat link! Took a while but i got there in the end...

You might need to take out the small washer under the B screw to get the cage wound out enough, or stick a longer screw in there to clear. I had to with an SLX and XT Long Cage Mech and a 11-42T

Mine (11-42t) is working OK with an older XT 10 speed Shadow (no clutch) - b-screw wound pretty much all the way in.
