How To Measure Chain Wear On A Bicycle Using Dial Calipers?

How do you calculate chain wear?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

How do I know if my bike chain is worn?

How much can a chain stretch?

The maximum allowable wear elongation is approximately 3% for most industrial applications, based upon sprocket design.

How often should I change my bike chain?

The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles.

What are the two types of calipers?

The first type is vernier calipers, which have a sliding scale along the top and bottom. The second type is dial calipers, which have a dial that displays the measurement via a pointer. The third type is electronic digital calipers, which have an LCD digital display of the measurement.
