Fascinating. Thanks for the detailed pictures. I'm having trouble with the derailleur not springing back. See clip:
This seems to be causing the chain to skip when it's on the smallest cog and under high torque. When I put another derailleur on the bike, it's springs back in a snappy sort of way. With the other derailleur, I don't have any trouble with the chain skipping no matter how much I mash on the pedals.
All the springs seem to be in tact on the original derailleur. I checked out the b-spring and re-greased it, but that didn't help. I'm wondering whether the super plate mechanism is what's causing the body to not spring back, resulting in chain skipping. I can feel the spring action in the super plate, but perhaps it's not strong enough.
