2018 brings with it a burning desire to measure things with a greater level of precision. In fact, you could say it's a new year's resolution. To that end, I'm going to buy a Vernier caliper. But which one? My initial thoughts are that a range of 0-150mm and a precision of 0.05mm should be fine for bike work. Does that sound about right? Any brands I should look out for / avoid? Advice welcome, although obviously recommendations for dial or digital calipers will be met with the contempt they deserve.
