FAQ (will update as necessary) Q. Can’t you use XT/XTR di2 derailleurs? A. For 11 speed no problem (I used that previously) but Shimano has not yet released any non-ebike 12 speed di2 MTB derailleurs. Q. What about the e-bike 12speed di2 m8150 RD? A. Will not pair with road shifters (to my knowledge, feel free to correct me) Q. What about the garbaruk cage? A. It’s made for the 11speed 817 RD which is 1x specific. Using that on this 2x 825 RD will cause the same clearance issues as shown in this video. Q. S-RAM? A. Don’t be silly now ;)

The main difference between the 1x and 2x derailleurs is the parallelogram pivot angle. They change this to suit the cassette profile, ie the angle (or steepness of curve to be more accurate) all the gears make from small to big. This is why changing cage doesn't really work properly. The 2x parallelogram angle is just too shallow for big cassettes.

For me, range was more important than 12 speeds so I did the XT cage mod to my 11sp 1x Di2 GRX with the 51-11 cassette and without a hanger extension and I have had zero problems.

Ha ha ha! I am not alone in my idiocy I did exactly the same thing earlier this week. I too twisted the cage the wrong way and bent the spring and crushed the plastic washer. My experiment is 11 speed RD-M8050 medium cage to long cage swap. For anybody trying this, when mounting the new cage make sure that everything is in alignment before tightening the main screw that holds the cage on the clutch - then turn the derailleur over so you can see where the spring hooks onto the cage and make sure to twist the cage in the direction that the hook on the end of the spring is holding the spring against the direction of rotation. If you go the wrong way like our buddy Mr Rides (and me) the spring will slip out of the cage and bend itself as shown. Good information that the spring and washer are available as spares - I assumed that they werent and reused the damaged pieces anyway - so far it seems to work as normal. Mounting on the bike today.

When the experiments work it's very satisfying.
