How to Measure a Mountain Bike Chain: A Comprehensive Guide
To measure a mountain bike chain, use a chain checking tool or a ruler. Place the chain on the checking tool and check the length to see if it is within the recommended range. If using a ruler, count the number of links and measure the distance between two rivets. The distance should be 1 inch or 12 1/8 inches for a brand new chain. If the chain is stretched beyond the recommended length, it may need to be replaced.
