What is chain pitch?edit
Chain pitch is the distance between any three consecutive rivets divided by two. Pitch defines the size of the chain. Carlton chain is made in several pitches – 1/4″ is the smallest, 3/8″ is the most popular. Other parts of the cutting elements are pitch-related. The drive sprocket must be the same pitch as the chain, and so must the nose sprocket in sprocket-nose bars.
