Hello everyone.
I upgraded my 14T-28T freewheel to 14T-34T freewheel (Shimano Tourney TZ500).
My bike used to have a Shimano Acera derailleur, 7-speed. Since then I've snapped my stock derailleur and replaced it with A Shimano Tourney. Why is this happening? Do you have any suggestions on what derailleur I can go for not to face this issue again? Also, the front derailleur is a 3-speed Shimano Tourney.
