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:

    I had an X9 derailleur that got destroyed in a crash, I replaced it with an x7. Thankfully the x7 got destroyed because the shifting was abysmal and I was looking for a reason to go back to the X9. The difference in price between X7 and X9 easily justify the major improvement in all areas. If you're on the fence go with the X9.

        This derailleur works great with sram 8 speed system. I used it with x1 8 speed trigger shifter and Shimon 8 speed cassette. It was a snap to install and set up. Jensen sales people are terrific.

          Having used SRAM Gripshift on my mountainbikes for two decades, purchasing this derailleur was an easy decision to make. For XC and All Mountain riding, the crisp shifting response and ease of servicing have made me a loyal customer for life.

            Running it with SRAM 990 Cassette, X7 shifter. Its a light weight set-up.

            Previously I had the same X9 and it was tough, served me well. Great on my DH/FR 8" bike.

              Comments about SRAM X.9 9 Speed Rear Derailleur:

              The SRAM X.9 derailleur slides that chain around your rear cogs like a control-freak-boss. Up, down, two or three at a time depending on hard you thumb the shifter. This derailleur eats rocks for breakfast, boulders for lunch, and mountains for dinner. And it does this consistently for years, with nary a peep of protest or whine of disgruntledness (<<< ya that's a real word). It's just that good. Buy one.

                Like SRAMs design using a lower force cage spring and the 1:1 pull ratio. Provides smooth shifting and great feel.

                    MY Stump Jumper Pro came with the XO which is a awesome derailleur but very costly so when it broke last week I went with the X9 as the price difference is huge but overall in my opinion works just as good. Also have the X9 on my '14 Scott Scale 730 and '11 X-Cailber. Can not go wrong with the X9!!! Jenson by far had the best price I could find and the shipping was crazy fast. The 2nd reason to use Jenson is because I ordered the XT the week before and it would no work with my Sram shifters so Jenson refunded me without any problems. A+ company!!!
