Dropped $85 on a chain wear gauge kit, then a guy at the Tuesday night ride showed me a $2 ruler does the same thing

Man, that ruler trick is even better than people make it out to be. You don't just check wear with it, you can measure chain stretch across 12 links and compare it to the spec, so you get an actual number instead of a vague "looks stretched." The gauge kit is basically a go/no-go tool, which means it tells you worn or not worn and nothing in between, but the ruler lets you watch the wear creep up over months. So yeah, the $2 version does more, just takes an extra minute of math.
