Squeaking in certain gear combos

rdmp2 · 2019-04-22T09:34:14+01:00

Any tips for tracking down squeaks? Very high pitched chirruping coming from somewhere when using big chainring combined with bigger half of cassette (bigger sprockets). Completely silent for big chainring with smaller sprockets and also small chainring all the way across the cassette. Thank you
