## How do you measure chain link?

1. Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line. …
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.

## How do I know what size bike chain I need?

The method of chain sizing depends upon the range of gearing in the system. For bikes with rear sprockets 36 teeth and smaller, the common system is to measure using the largest rear sprocket and largest front ring as a reference. Two rivets are added to this (one-inch) for the place to cut the chain.

## What size chain is bicycle 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.

## How do you specify a chain size?

How to Tell What Size Chain You Have

1. The distance from the center of one pin to the center of the next pin, also known as the “pitch” of the roller chain.
2. The diameter and width of the roller.
3. Plate thickness, determined by measuring the plates from one flat side to another.

## How do you measure the width of a bicycle chain?

It is measured by measuring the distance between 3 links, then dividing it by two.

1. Chain pitch is shown with green markers, though it is determined by measuring the distance between 3 adjacent pins (blue mark) and dividing it by two.
2. Inner chain width, marked with blue arrows and lines.
3. From left to right:

## Are bike chains universal?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

## How do you measure a chain and sprocket?

To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
