I've had a new ek chain along with a new set of sprockets fitted to the bike less than 1000 kms. Today, as I was examining the chain and measuring slack, I noticed one of the o-rings on the master link hanging off. My local shop won't have a replacement master link for a week and a half. My question is whether I should pull the hanging o-ring out? Leave it half wedged between the plates? Ride like normal or avoid riding and source a replacement link sooner.
