Granted, I have only had a chain checker tool for a few years. I have never measured a chain that is worn out, according to that tool. Some of my chains are a decade old, if they're a day old. Some of those chains have 10,000 miles on them. Yes Virginia, I was once a serious cyclist. Don't let Big Bicycle (or your anxieties) run your life.
Perhaps they don't make chains like they used to. I have installed one new chain over the last ten years. I think I have made my point
