    Will XT M772 rear der. 9 speed work with 8 speed shifter/cassette?

    I need a new medium cage rear der.
    I am running M952 XTR shifter and cassette 8 speed that works fine.
    I understand that 9 speed stuff will work with 8 speed, but is that true for all 9 speed shimano stuff, including 'shadow'? I know the 10 speed Dyna-sys rear der. will not work.
    I just do not want to compete with retro crowd for a rear der. on das bay.

    Thanks!

    Yes, 7-9 speed all use the same pull ratio and you are also correct, 10-speed will not work. I've used Deore m592 / SLX m662 shadows on friends Alivio 8 speed.
    Rgds,
