This is exactly what I do. However, I know about trimming derailleurs and so even when I nudge the front derailleur I cannot stop the chatter. So, what can that mean? But it does go away in other gears. I’m stuck with chatter in the HARD-HARD. (Leahspeak for whatever those gears are called. I have no idea which one is “high” and which one is “low.” I know hard and easy.
