    Should my rear derailleur rotate?

    I've been having some poor shifting. The bolt attaching my rear derailleur to the frame was loose enough to allow the entire derailleur to rotate on this pivot. It seems to have some kind of a spring mechanism, so I thought this was correct. But now I'm not so sure. So I tightened the bolt up. Which way is correct?

    I have an XT traditional rear derailleur.


    Thanks,
    Jamie

    the mounting bolt should be tight and the derailleur should be able to pivot.

    The trouble with common sense is it is no longer common

    Okay, but when I tighten the mounting bolt, it won't pivot. What am I doing wrong?

    torque the bolt to 75 in/lbs

    It seems like there are two black plates that should slide past each other to allow the thing to pivot. As I tighten the bolt, they get closer together, and when it's tight enough, they no longer pivot. I don't have this problem with the derailleur on my road bike.
