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 ;)
@neiltwaterhouseАй бұрын
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.

One can easily modify the shadow arm by filling off a little material on the index nose so that it points more vertically down. This is often times enough to create sufficient space between the upper pulley wheel and the cassette. In rare cases it becomes necessary to swap the b tension screw out for a slightly longer one

@mgreene888Ай бұрын
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.
@ridesofjapanАй бұрын

Good to see you again, Roj. In your opinion, is it worth replacing my Ultegra 9200 Di12 (50/34 and 11-32 Dura-Ace cassette) with this new GRX? The purpose would be to lighten my bike (Bianchi, mod.

To save weight? Than No, GRX will be heavier. Just to be clear, you mean ultegra 8170 right? (9200 is dura ace). Also think you mean 11-34 cassette? No 11-32 12speed cassette available from Shimano.

When it came to 12speed gravel and MTB..........nothing. I ride a Specialized Creo 2 and need 1x as 2x will not fit. It came with 12 speed SRAM wireless, which I have found to be rather good. Shimano as so far behind the game in 12 speed Di2, they are missing the cut !!!!

you could still have messed with the b screw, with a di2 setup, you kinda have some room to go out of ideal adjustment, this would make the derailleur compensante the lack of tension on the highest gear, I could work, the draw back would be shifting getting slower
@andrejkissАй бұрын
I had a similar experience with the goatlink. Yeah it clears up to 52T, but shifting at 11-15 is less than optimal. In the end I went with Sensah SRX and now I have perfect shifting from 11 to 52 with 46 chainring.

That seal you mangled is actually a thrust type bushing preventing cage from rubbing against the main body.

Lol. Experimenting with Shimano parts out-of-spec is fun. Shimano has a 12-speed Di2 RD for eMTB (RD-M8150-12). Do you think the cage from that unit might work? 😆 I recently put a cage from a 8150 RD onto a 9250 RD so that I could run a 11-36 cassette on the 9250. It works like a charm. When the experiments work it's very satisfying.
