I'm curious about the lifespan of a Wippermann removable link. How many chains are they good for? Mine looks like it's wearing on the inside where the rest of the chain makes contact with the side plates, but I don't have a new one to compare it to. This one has been through maybe 2 chains and 6,000 miles. Maybe I should just buy a new one and keep this one in my seatbag for a backup.
