Cheers. I need to have a closer look at why it broke and why the RD wasn't moving after it broke so there could be a bigger issue I need to resolve than cables. It doesn't really get used enough to warrant a Di2 swap but perhaps I could find a cheap new DA cable group and throw it on.

Oh, any idea if the RD jockey wheels are supposed to move left to right on those 7800 deraillers? They seem to have some play in them.

The upper wheel (guide pulley) should have some slack in order to keep the chain aligned with the sprocket.

The lower wheel (tension pulley) shouldn't.

I don't recall which one I was playing with. It seemed to have a wider range of movement to what I'd expect it to have but its been so long since I played with that derailler I have no idea.
