Chain broke while commuting the other day - I managed to repair it at the time with a quick link, but the new link seems to be catching slightly when going through the derailleur. Every 4ish rotations of the pedals there’s a very brief sound like I’m freewheeling, and the derailleur starts pulling back when in top gear, but I can’t replicate any of it when the wheel’s off the ground.
Might just be a dodgy quick link causing problems, but does anyone have suggestions while I wait for new ones to arrive?
Tightness is a good idea, I’ll see if I can work out anything related to that while I get a new chain and cassette.
