Have an issue with a KROMCHY sound in the highest (11t cog 40t chainring) and the 3 lowest gears, presumably it happens only in these gears as the chainline deviates from straight and something is worn.
Fiddled around with derailleur adjustments, replacing the whole thing and testing different pulley wheels, made no diff.
Presumably it's not the cassette as the low gears hardly get any use (flat here), which leaves either the chain and/or the chainring (superstar narrow-wide)?
