Tested the XT Dyna-Sys Cassette 11-36T, XT Dyna-Sys RD SGS 773 and Ultegra 6600 shifters. It didn't work at all. The Dyna-Sys have a different pull ratio than road shifters. It only works with the XT MTB Dyna-Sys shifters. I will stick to my SRAM 11-32Tand XT 9spd RD772 set-up.
I tried 11-36 Dyna-sys with 6700 brifters and XT 9 spd RD. Shifting isn't smooth at all and sounds clunky with the chain in the 36 sprocket, even with B-tension screw adjusted. The SRAM 11-32 pg1070 cassette has been working fine 6700 shifters and XT 9spd RD. The gearing range of the 50/34 compact with 11-32 cassette is quite close to a 52/39/30 triple and 11-28 cassette.
I'm using pre-shadow top normal. I have a shadow top normal on another bike. I'll swap 'em and give it another try. Glad yours works.
I have a shimano shadow rear derailler with 10-speed 105 brifters, and a XX(the only available in this size when I bought it) 11-36 casette and shift quality is very poor. What kind of cassette are you using?
