My another plan is going to replace my RD Shimano Alivio by RD XT 2012 Dynasis 10 speed. I tried to find that at Amazon but I could not find it and only found Shimano RD-M772 XT Shadow Rear Derailleur, GS. 9 speed.
Seem it is cheaper than 10 speed, but anyway this is still what I expected to get improvement in performance. I did the test ride of the friend of mine’s bike where it is RD-M772 9 speed, it was awesome! What I got was nothing short of a miracle! Once I got this very light in on the cable adjustment it was on! When downshifing on inclines, I felt like I had an incredible transmission! I couldn’t even feel the upshift. That derailleur is outstanding.
