How is chain pitch measured?
To determine the pitch (chain size), you’ll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.
