Hi all! I’m new to the world of bike mechanics after I crashed a few weeks ago and found my rear derailleur stopped shifting, so I used the situation and my inability to properly move (thanks cracked ribs and road rash!) to learn how to fix my bike up myself! It’s an old Ribble Gran Fondo 2014 for those wondering.
I had a new chain put on back in July last year however I’m not sure how old the cassette is as it was a bike given to me bike a friend. I replaced all the gear cabling and took it out for my first ride back and found when I was in the small ring and second largest cog on the back my chain was skipping (as in first image). I also had an issue with it skipping the same cog when shifting up which I seem to have fixed by changing the B limit.
Is my cassette worn out, or my derailleur appear bent or out of line?
Please excuse the mismatched rear derailleur, as I say it was a very kind hand down bike.

Have you tried fine tuning with the cable adjuster? It’s that semi-knurled thing just before the cable goes into the RD.
What shift levers are on this bike? I see a Campagnolo front derailleur and a Shimano 105 R7000 rear derailleur, so I’m wondering what levers are on the handlebars. If you are not using Shimano’s 11-speed levers, that R7000 rear derailleur is not going to shift correctly.
