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?
Just throwing ideas out here, as I can’t identify any specific cause. Maybe the quick link isn’t the right size for the chain? Maybe it’s not fully snapped together? You should test the individual pivots on the link and see if they’re stiff and need to break in, that could be another cause.
Could your derailleur be between gears? Have you tried dialing it in? Check out Park Tool’s repair videos on YouTube, very in depth and helpful for learning bike maintenance.
Definitely the right size and properly snapped together, but stiffness might be the case like enkifish suggested as well. I don’t think it’s between gears, I’ve had that issue before and it didn’t have the freewheeling sound. I’ll have a look at the channel and see if any of it helps though, thanks.
