I don’t quite understand why so many have doubts or skepticism about the accuracy of chain measuring tools. I get that your preferred way of measuring a chain is using a steel ruler, or a caliper. That’s fine. There’s nothing wrong with that. It’s an acceptable method. Before I got the tool I currently have that’s how I did it. But why is there skepticism about the accuracy of tools specifically designed for the task? I feel like it’s akin to saying something like “I don’t trust Park Tool wrenches because they’re inaccurate. Their tools aren’t the size they say they are.” No...Park (and others) makes quality tools (IMO). They produce a tool that they say is precisely a 15mm wrench and it fits 15mm nuts/bolts, or a crank remover with a specific thread count that screws into your cranks (for examples). Why wouldn’t they be able to produce a chain measuring tool that precisely measures 12 inches?
