How to Find Chain Size

When it comes to finding the right chain size, whether it’s for your bicycle, motorcycle, or any other equipment, it’s important to know the correct measurements. A properly sized chain ensures optimal performance and longevity. So, if you’re wondering how to find the right chain size, here are a few steps to guide you:

1. Determine the pitch: The pitch refers to the distance between the centers of two adjacent chain pins. Measure the distance between any three consecutive pins and divide it by two. This will give you the pitch measurement.

2. Count the links: Count the number of links in your chain. A link is composed of two inner plates and two outer plates. Make sure to count all the links accurately.

3. Check the width: Measure the width of the chain. The most common widths for bicycle chains are 1/8 inch, 3/16 inch, and 3/32 inch. Motorcycle chains have different standard widths, such as 525, 530, or 630.

4. Consider the type: Chains come in various types, such as single-speed, multi-speed, or specialty chains. Make sure to choose the appropriate type for your equipment.

5. Consult the manufacturer’s specifications: Check the equipment manufacturer’s specifications or user manual for any specific chain requirements. They may provide you with the exact chain size and type suitable for your equipment.

6. Seek professional advice: If you’re still unsure about the chain size, consult a knowledgeable professional at a bike shop or dealership. They can help you determine the correct chain size based on your equipment’s specifications.

Finding the right chain size can be a bit confusing, so here are answers to some frequently asked questions to provide further clarity:


1. Can I use a chain with a different pitch size? No, using a chain with a different pitch size can adversely affect the performance and safety of your equipment. Always use the recommended chain size.

2. How often should I replace my chain? It is recommended to replace your chain every 1,000 to 2,000 miles, depending on usage and maintenance.

3. Can I shorten a chain to fit my equipment? Yes, chains can be shortened if necessary. However, it’s important to use a chain tool and follow the proper procedure to ensure a secure connection.

4. Are all bicycle chains the same size? No, bicycle chains come in different sizes, depending on the number of gears and the type of bike (e.g., road bike, mountain bike).

5. Can I use a motorcycle chain on a bicycle? No, motorcycle chains are generally much heavier and wider than bicycle chains. They are not compatible with bicycles.

6. How can I measure the width of a chain? Use a caliper or a ruler to measure the width between the inner plates of the chain.

7. Are there any specific lubricants for chains? Yes, there are specialized chain lubricants available in the market. Using the right lubricant can enhance the chain’s performance and durability.

8. Can I use a chain without any lubrication? It is not recommended to use a chain without lubrication as it can lead to increased friction, wear, and potential damage to the chain and other components.

By following these steps and considering the FAQs, you’ll be able to find the correct chain size for your equipment, ensuring smooth operation and longevity.
