I've just replaced my front mech and chain (no problems there) but I'm now having an issue with the alignment of the rear derailleur. When on the big chainring and in the smallest three sprockets, the jockey wheel runs onto the outermost plate of the chain links instead of between the plates, then falls into place a moment later. This does not happen in the inner chainring (not that I would be using those combinations when riding!)

I have tried loosening the h-limit screw on the rear mech as far as it will go, but it doesn't make any difference. I was not having this problem before replacing the front mech, but can't see why that would affect the rear mech :?

Any suggestions? DA 7800 mechs, KMC X10 chain if that is at all relevant.

    Well, that was embarrasingly simple in the end. I guess it's been an issue for a while and I just hadn't noticed - all that was needed was to tighten the bolt holding on to the derailleur cage :oops:
