Guys
I’ve tried swapping my cassette over from 12-27 to 12-29 to help a little with my hills efforts, my crank is 53/39.
When I’m on the small chain ring and in first gear it does not run smoothly, the rear derailleur appears to jump about but it’s perfectly fine when I move to the second gear. I’ve tried re-calibrating the gears and it’s made no difference.
Chain length is not an issue as it works perfectly in first gear when I move to the large chain ring, I appreciate that the angle is not ideal.
What am I missing or is it just that the cassette is not compatible with the derailleur?
Thanks for your help.
Cheers
Lee

Is there an adjuster screw on the derailleur?
Not rhe H or L screws.
If yes, adjust this to drop the jockey wheel away from the cassette.0
