Didn't buy my rear derailleur at Jenson, but found a similar deal a few moths ago, installed it and combined with the x.9 shifters, new shimano deore xt CS-M770 cassette, deore M590 Crankset and the existing Deore front derailleur my shifting is 100% more smooth and efficient. Makes riding my '11 Trek Mamba a joy to ride compared to the shoddy x.4/x.5 and low grade shimano crank/cassette that came stock on it. Worthy & worthwile upgrade!

I 've been using SRAM derail. for around 6 years. The shifting is great but the durablity is somewhat to be desired. The plastic where the chain gap adj. screw can break (hitting the derail. on a rock or a stick )rendering the derail. useless.

      Comments about Sram X.9 9 Speed Rear Derailleur 2010:

      I am more of a shimano loyalist. I recently bought a bike decked out sram and had to swap out the rear derailleur. I wanted to keep it in the stock configuration so I bought the x9 replacement. It shifts well and does its job. I like the action on the shimano better.

      I've had one X9 for two years now, and after banging on countless rocks it still works decently, I am getting a new one for my DH rig, and the old one will go to my XC bike now. These things are good!

        Put this on a 7 speed and it worked great, shifts cleanly, and is a great replacement for an old XT. Had to change my shifters though.

          Got the mid length cage and it is just long enough with a 34 tooth cog with a 42 tooth chainring. Works flawlessly.

            Exploded old x.9 (the rock won)Replacement went right on and adjusted quickly. Jenson shipped quickly and I was back riding in a week. Bike is now good as new.

            Light and easy to install, but needs some tinkering to get adjusted. After that is smooth sailing though!

                I replaced an X5 long cage with this X9 medium cage. Works great, quiet and shifts smoothly.

                    After using Shimano for decades, I've started shifting over to SRAM products. Love the short cage as I'm now running all 1x9 drivetrains and have no use for the medium and long cages.

                    I purchased this to replace an X5 that came with a recumbent trike built for long haul touring. So far the X9 has proven to be totally reliable; shifts quickly & smoothly; fairly quite compared to the X5, no problems so far in the 300 miles I've put on it since putting it on.
