Featuring Shimano’s innovative Shadow clutch technology, the Deore XT rear derailleur is designed for today’s aggressive style of trail and all-mountain riding. By maintaining chain tension, the Shadow system eliminates chain slap and lowers the chances of dropping your chain. Other improvements include reduced noise and rotational drag as well as a low-profile pulley cage for better clearance over harsh terrain. Why choose an XT derailleur over a cheaper derailleur? Built for heavy duty and long life in demanding trail conditions, the XT's overall linkage is stiffer and has a more machined construction, increasing durability and stiffness, which also increases shift quality. The pulleys are also of a higher quality, and spin easier for less drivetrain drag. The whole derailleur is built to exacting standards and will last significantly longer than a cheaper derailleur as well.

Don't know which cage length to choose? Choose a long cage "SGS" derailleur if you have 3 chainrings on your crankset, and a medium cage "GS" if you have 2 or fewer front chainrings.

  • Compatible with 10 speed drivetrains
  • Uses Shadow derailleur clutch
  • Low profile pulley cage
  • Weight: 258g

I bought this derailleur to set a mountain bike up as a 1x10 with a narrow wide chainring and so far have been very pleased with the results! I have taken the bike on several rides, and have really enjoyed improved shifting performance and have yet to experience a chain drop (knock on wood). If you're looking at this product, you probably know that XT is one of the industry standards in balancing quality, performance, and durability; this derailleur is no exception!

Installed to replace a non clutch XT mech (stick ripped apart the direct mount hanger), works well out of the box and shifts well. Unfortunately though, it seems to be made out of cheese and could not survive a small knock which bent it to the point I cannot get lowest gear.

Just simply not worth the money when you are paying for light weight materials that cannot take any knocks, it is mountain biking after all.

All in all, 4 months of bliss, should be at least 4 years.

        Comments about Shimano XT RD-M786 Rear Derailleur:

        I love the clutch which snugs up the chain and greatly reduces chain slap. Just have to remember to relaease it when removing the rear wheel to change a flat. Otherwise I engage the clutch and leave it. Stellar!

                  Buy it.

                  Can't go wrong for any 10speed application.

                  I used it to make a 10speed with a 38t raceface, M771 XT 11-36, XT M780 rear shifter, & SRAM PC 1071 chain. With the intention of making a back woods thrasher. So far so good. Very impressed with its function. NO drop chains with the clutch.

                    I wiped out some time ago and destroyed my RD. Decided to use shimano instead of the other S brand. Boy was this a big upgrade in performance and also a big down grade in price. Shifting is without hesitation, very smooth. Im running this on a 1x10 with WT 42T and RF 32t.
