• Is it possible that my derailleur cage is twisted/bent? It seems to be at a slight angle to what the chain line should be and the chain is jumping on the jockey wheel as a result.

    I checked the gear hanger both on the bike and off the bike against a flat surface and it seems to be straight.

    Not sure what the issue is so any help/thoughts appreciated.

    See attached photos.
