How do you determine bike chain length?

How do you measure chain size?

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.

What size chain is a bike chain?

The chain in use on modern bicycles has a 1⁄2 inch (12.7 mm) pitch, which is the distance from one pin center to another, ANSI standard #40, where the 4 in “#40” indicates the pitch of the chain in eighths of an inch; and is standard 606 (metric) #8, where the 8 indicates the pitch in sixteenths of an inch.

Chain Link Sizes: How to Measure Chain Link Sizes

  2. Determine your side plate height and thickness by measuring both inside and outside the roller chain to ensure that you’re seeing a good average size.

Are all bicycle chains the same size?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. … However, this does not mean all makes and models of chains are interchangeable. There are two basic types of bicycle chains: “one-speed” chains, and derailleur chains.
