Skip the XTR, get this

I had to replace my rear derailleur for the first time on my Specialized Stumpjumper. It came with an XTR version of this (2-3 years old now) and the old one got clobbered in a fall (maybe two?). When I went into the store to get a new one I was in sticker shock over the $200 price tag for the XTR. I said no thanks and did some research. The differences between this model and the XTR are minuscule and not worth the extra money. After a few hours of work I had this working and it shifts just as beautifully as my old one. This will be my standard from now on.

Be careful in your selection of the model you are looking for as there are differences for different bikes, different gears, etc. They make them all and you need to get the right model. This is particular one is probably the most common though. You should replace your shifter cable at the same time too. Instructions that came with this are pretty good, but could be a bit better.

Absolutely Amazing!!

Got this puppy to replace a stock Shimano Alivio and expected an improvemetnt in performance. What I got was nothing short of a miracle! Once I got this baby tweaked in on the cable adjustment it was on! When upshifing on inclines, I felt like I had an automatic transmission! I couldnt even feel the upshift. Even under full load out of the saddle this derailleur is outstanding. I am amazed at the difference this component has made. My bike feels like a $2000 package! Bravo Shimano!
