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.

      I bought this because my old derailer broke, so I decided to give this one a try. It was totally worth it. It shifts gear nice and clean, and looks like it will hold up pretty well on the trails.

            Great XT derailleur. Does everything a der. should. Great shifting and the shadow plus is worth the upgrade alone. Much quieter ride on the rough stuff now.

                    Changed my GT avalanche from a 3x9 to a 1x10 and everyone said to go with the Shimano XT with a cluth. When the system is on it tightens the spring for the arm and reduces the amount of chain slap or play. Before this I had a lot of chain drops. With the XT derailleur, the shifts are smooth, crisp, fast and the amount of chain drops has gone to zero. Thank you Jenson USA for all the advice and amazing prices.

                      I'm a competetive xcountry rider. I have always been happy with my Shimano gear, but recently upgraded to the xt drivetrain!! What an awesome derailleur! Lightweight, looks sweet, and super smooth shifting. I personally have neen happy with my 10 speed, so didnt upgrade to the new 11speed. Xt is well worth your money!

                            A:

                            Yes, assuming that your cassette and crank are 10 speed, this derailleur will work fine with your crank and cassette. You need the "long cage" option to accommodate your current gear range. Make sure to select that option in the drop down menu when placing your order.
