Chain only runs cleanly when I keep the shifter pressed (self.bikewrench)

Hi all

When I'm on the biggest wrong on my rear sprocket I can hear a light ticking noise when I pedal.

The noise goes away when I keep the shifter pressed down, as the chain is then properly aligned with the sprocket (I think)

How would I adjust the derailleur to fix this? Do I need to change the limit screw or just the tension of the cable?

Pointers into the right direction are appreciated 😅

Thanks!

If you can make it go away with the shifter, I would guess it is not the limit screw but that cable tension (I don't think the shifter would help alleviate the problem if the limit screw is set too far in). You could start with using 1/4 turn increments of the barrel adjuster at the shifter. Go slow. Do one 1/4, shift around and stop back on large cog and see how it sounds and looks.
