Here’s my review of my favorite measurement tool in my shop, Mitutoyo 6″ digital calipers (model number 500-196-30). Being able to get more reliable measurements is incredibly valuable if you care about precision. I procrastinated way too long on buying these and I use them all the time now. The ability to convert between inch and metric is so convenient for bicycle framebuilding. Taken together with the ability to zero the measurement, and various other tricks I show in this video, this all makes the investment easily worthwhile.
