And once it goes slack it can dump itself pretty much anywhere on the cassette as there's nothing to guide where it lands. The real root cause is that derailleur bicycles simply are not designed to be pedaled in reverse - the chain has no guide when doing that. | |

Zooming in on the picture, the chain, pulleys, and cassette are all pretty dry with a good amount of surface rust on them. I agree that a good clean and relube of the drive line will probably fix it. | |
