Hey guys thanks for any help. I am a first time chain driven bike owner. I noticed while cleaning the chain last week that the rivet on the master link was missing part of the 'mushroom.' Is this something I should be worried about? The chain is an EK 530 ZZZ with like a 11,000 lb/ft rating or something. Not sure how old it is though. Looks in decent shape I think otherwise. Thanks.
