I have a Shimano CN-HG53 chain and want to remove it for cleaning.
Do I need to simply buy a chain tool and push out one of the pins to remove and then push it back in to replace or do I need to replace with a new pin?
There appears to be one link that looks different. It has a flat single pin in it. Is this the one I should be working with or is this one that has simply been grinded down?
IS there a type of link that I can buy to put in my chain to facilitate easier frequent removals?
