Shimano XT RD-M772 9SPD Rear Derailleur

The New Shimano Shadow Rear Derailleur places priority on a low profile design for riders that are at home on technical trails.  The derailleur has a profile that is a full 15mm narrower than a traditional rear derailleur. That means it does not protrude more than the quick release skewer nut.
  • Top normal spring design to mesh with the more common choice of RapidFire shifters for trail/all-mountain riding
  • Direct cable routing reduces the chance of the cable snagging on roots and rocks
  • Stronger spring keeps the derailleur body more stable in rough terrain
  • Redesigned bracket axle keeps the derailleur body from contacting the chainstay
  • Designed to allow for easy wheel removal
  • Weight: 227g(SGS)

The Shadow technology works well to keep the profile of the derailleur low and close to the bike. Another benefit is the more direct cable routing that removes the "loop" Shimano is so famous for (and which is the cause of so many shifting problems on poorly maintained bikes).

With that said, it can be very tricky to get the derailleur set up well. Some combination of the more direct cable routing and operation of the derailleur means it is very picky about cable and housing condition and routing. It takes me longer to set up these derailleurs than on the non-Shadow models.

The shifting on the derailleur is excellent when it is set up correctly and it has eliminated a lot of the derailleur to chainstay contact noise.

Was great to install. But when it came time to run the cable, I found out that it did not have an adjustment screw for fine tuning. When I looked into re-using my old Deore screw, I saw that the XT did not even have the threads to install an adjustment screw of any type. Unless the screw type is outdated to a new type (which was not included) I have to really play with the cable end stop to tune it. But the kicker is that the instructions have notes about how to tune with an adjustement screw once the cable is installed.

      The cable routing is directed inward and puts the loop directed outward. Small concern that it may catch on brush on narrow trails.

        I purchased this as an upgrade for my son bike. His Rocky Mountain Soul came with a Shimano Alivio that was performing poorly when trail riding in serious conditions. Lots of chain slapping and occasionally the chain would come off even when properly tuned. The new shimano xt shadow shifts incredibly fast and no more chain slap even on the hardest trails. Problem solved

          Replacement for an old derailleur on my winter commuter Trek 8000. I really like the new mount design for direct mount compatibility. Having B-tension adjustment internal to the part seems to be a more robust design.

              It was time for a new derailleur on my 12 year old bike. Derailleurs have improved greatly in that time. This one works much more efficiently and is designed to have a lower profile that doesn't hang out away from the rear triangle. Works great!

                            Andy! If you are referencing the rear cassette I don't think anyone makes a 9 speed cassette that went to 36 teeth. If you know of one, GREAT! That derailleur should work fine with a 36t cassette provided it is 9 speed. Depending on your front end set up (2 or 3 chain rings) I would recommend the SGS option.
