Old M952 XTR, or new M772 XT rear derailleur- which one to use?
I'm throwing together a new bike for all-mountain use, and was intending to use one of my good ol' M952 XTR rear derailleurs, when I remembered I have a new M772 XT rear-d in my parts bin.
-The XTR is lighter, but the XT has a few improvements in design with the cable pull relocated and the second pivot point, plus longer hinge pins which may make it more rigid.
-The XT is longer than I could ever imagine needing for a 11-34T against a 22-32 double, and the aluminum cage seems like a soft alloy to me. Both are long cage models, with the XT being 25mm longer in the cage than the old XTR. Oddly, the uber-length XT is marked for Mega-9, but should fit a 36T tenner just fine if I decide to later...
I'll be running 9-speed on a M960 cassette and M952 shifter pods. Any thoughts on which would be the most suitable given the choice?
