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?
I used to wrench on motorcycles not push bikes but I assume the chain and sprocket are pretty similar.
Second replace chain and sprocket, they wear each other down together and introducing new components will mesh slightly differently causing too loose or tight engagement which can cause weirdness.
Also if new link is too tight, I don’t exactly know how a quick link works but this happens with botched rivet jobs on vroomy bikes anyway, then it might be lifting the chain slightly as it rolls over. Messing with the free play.
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.
