I have the DH-specific 7spd GX shifter, derailleur and the fancy one-piece cassette.
This happens sometimes after a rough descent:
Picture the chain wrapping around the cassette, and then instead of the chain wrapping around the top pulley of the derailleur, it appears to sit 'on top' of the teeth of the pulley. It just takes a little bit of shifting and more riding to get the chain/pulley back to normal. It's not the end of the world; it just makes some clicking and clacking noises and I was wondering if anyone else had that issue. I tried messing with the B-screw but I don't think it has much affect with this configuration of drivetrain.
