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.

    OK, this is a fantastic derailleur that works very well. My first of the Shadow style. I give it 3 stars because I spent extra for a shorter cage length (GS model) that is only 10 mm shorter than the SGS, and the instructions don't include anything about the 2nd pivot point and mounting of the derailleur to the dropout. I'm mechanically inclined, it took me a test ride and a close inspection to get it all dialed. SHimano, Where are the setup vids on Pinkbike or VitalMTB? Oh and I like rapid-rise. THis is only offered in the classic style as far as I could tell.

            Comments about Shimano Deore XT M772 Rear Derailleur:

            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 Unless the screw type is outdated to a new type (which was not included) I have to really play with the cable end stop to tune it.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.

              Upgraded to this from a non-Shadow LX. Was easy to install and tune. Has held up well so far and shifts smooth eliminating some chain slap. For anyone looking to boost a 9 speed drivetrain to that next level, it's very much worth the price.

                a good rear derailleur, but the SRAM competitors get my nod. As a shadetree mechanic the SRAM products seem much easier to me to 'get right'.

                  I replaced a Deore 9 speed derailleur with this xt version and the difference is amazing. I"m using with alevio shifters yet it still shifts perfectly. This product can't let you down, It's engineered to shift perfectly and that is what it does. Buying this product has been a definite performance increase to my bike,

                    Comments about Shimano Deore XT M772 Rear Derailleur:

                    I purchased this to replace an older XTR rear derailleur that had suffered some pretty serious damage. I was really concerned that I would loose performance going from the XTR down to the Deore XT but IF I did it isn't noticeable to me. It was very quick and easy to install and adjust and shifts perfectly every time.

                    So far I have only put about 50-60 miles on it so I can really comment on the durability but I couldn't be happier with the performance. I don't think there is a better rear derailleur for the price available.

                      Used this to replace an old XTR derailleur. Had to cut the cable housing a bit due to the shorter routing, but it was easy and took about 15 min to install. Shifts perfectly, and if you've got 9 speed components this is a great purchase.
