Mountain biking can be a thrilling and enjoyable activity, but regular maintenance is essential to keep your bike in top condition. One of the most crucial parts of a mountain bike is the chain, as it is responsible for transferring power from the pedals to the wheels. Over time, the chain may wear out or become damaged, requiring a replacement.
Changing the chain on a mountain bike may seem like a daunting task, especially if you’re not mechanically inclined. However, with a few essential tools and the right steps, you can easily replace the chain yourself. In this article, we provide a step-by-step guide on how to change the chain on a mountain bike to help you save time and money in the long run.
Preparing for a Chain Replacement: Tools and Materials Needed
Before you dive into the process of changing your mountain bike’s chain, it is crucial to make sure that you have all the necessary tools and materials at hand. Without them, you risk damaging your bike, and the replacement process can be very frustrating. Here is a list of everything you’ll need:
1. Chain tool – You definitely need a chain tool to break the old chain and size the new one correctly.
2. Replacement chain – Choose a chain that is compatible with your bike’s model, and make sure to get the right size.
3. Lubricant – You need to lubricate the new chain to ensure optimum performance and to lessen any damage to your bike’s gears.
4. Chain pliers – You’ll need them to remove the quick release pin holding your bike’s chain.
5. Clean rags or towels – These are essential for removing an old and dirty chain and cleaning the bike’s chain.
6. Gloves – Wearing gloves will keep you free of oil and any dirt and grease that may rub off from the chain. With all the above tools, you are ready to start the chain replacement process and do it well.

Identifying Chain Wear and When to Replace It
Identifying Chain Wear and When to Replace It
The chain is an essential component that transfers power from the pedals to the rear wheel. Over time, the chain undergoes wear and tear due to the constant movement and exposure to dirt and debris. A stretched or worn-out chain can affect the performance of your bike and can lead to other component failures. The easiest way to determine if your chain needs replacing is by using a chain wear gauge. This tool measures the amount of stretch a chain has undergone over time, giving indication of the amount of wear it has undergone. If the chain measures above 0.75% on the gauge, it is time to replace it.
A worn-out chain can cause shifting issues, and in severe cases can cause the bike to skip gears or prevent the rider from shifting at all. Additionally, a worn-out chain can cause unnecessary wear and tear on other components such as the cassette, chainrings and jockey wheels, which in turn may also need to be replaced. It is important to replace the chain regularly to ensure smooth operation of the bike and to prevent other component failures.
Remove the Old Chain: Step-by-Step Guide
Removing the old chain from a mountain bike is a crucial step in replacing it. However, it can be a daunting task for beginners. In this step-by-step guide, we will help you remove the old chain with ease.
Firstly, shift the bike into the smallest cog in the rear and the smallest chainring in the front. This will loosen the tension on the chain. Next, find a master link, which is a special link that allows you to easily remove the chain from the bike. To find the master link, look for a different color or different style of link on the chain. Use a chain tool to push the pins out of the master link and remove it from the chain. Once the master link is removed, the chain can be taken off the bike. Be sure to properly dispose of the old chain as it is hazardous waste.

Measuring the Length of the New Chain: Tips and Tricks
Measuring the length of the new chain is an essential step in replacing the chain of a mountain bike. A chain that is not properly fitted can cause slipping, skipping, and other issues while riding. The good news is that measuring the length of the new chain is a simple process that requires only a few tools.
To measure the length of the new chain, start by placing it around the largest chainring and the largest sprocket at the back. There should be no tension in the chain at this point. Then, add two links to the length of the chain and cut off the excess. It’s important to ensure that the new chain fits snugly across all gears without being too tight or too loose. Additionally, it’s a good idea to check the width and pitch of the chain to ensure it’s compatible with the bike’s drivetrain. With these simple tips and tricks, you can replace your mountain bike chain with confidence and get back to riding in no time!
Installing the New Chain: Step-by-Step Guide
Installing the new chain is a crucial step in changing the chain on your mountain bike. This step-by-step guide will help you install a new chain like a pro. First, lay the new chain out on a clean surface and identify the master link. The master link is typically distinguished by its different appearance.
Next, thread the chain through the derailleur, starting from the bottom pulley. Then, pull the chain through the front derailleur and place the chain on the smallest cog of the cassette. When both ends of the chain are in line, insert the master link and snap the plate into place. Finally, pull both ends of the chain to ensure the master link is securely in place. Once you’ve completed these steps, you can start riding with a new, functioning chain on your mountain bike.
Adjusting Chain Tension and Shifting Performance
Once you have installed the new chain on your mountain bike, the next step is to adjust the chain tension and shifting performance. This is important because improper tension can result in poor shifting, excessive wear on the chain and cassette, and even potential damage to the derailleur or frame.
To adjust the chain tension, first, shift the chain onto the smallest chainring and smallest cog. If the chain is too loose, use a chain tool or derailleur to remove links until the tension is correct. If the chain is too tight, use the derailleur to increase tension or add links to the chain. Once the chain tension is correct, test the shifting performance by shifting through all the gears. If there are any issues with the shifting, adjust cable tension and limit screws as needed. With proper chain tension and shifting performance, your mountain bike will perform smoothly and efficiently on the trails.

Maintenance Tips to Extend the Lifespan of Your Bike Chain
Proper maintenance is key to extending the lifespan of your mountain bike chain. Here are some maintenance tips to follow:
1. Keep Your Chain Clean: Dirt and debris can cause excessive wear on your chain, so it’s essential to keep your chain clean. Use a chain cleaning tool and a degreaser to clean your chain thoroughly, and then rinse it with water. Dry the chain with a clean cloth or towel.
2. Lubricate Your Chain: After cleaning your chain, lubricate it with bike chain lube. Apply the lube sparingly, and wipe off any excess. A well-lubricated chain will run more efficiently, last longer, and reduce noise.
3. Check Your Chain for Wear: Over time, your chain may start to stretch and wear out. A worn-out chain can cause gear skipping and damage to other components. Check your chain for wear using a chain checker tool. If your chain is worn out, replace it immediately to avoid further damage.
By following these maintenance tips, you can extend the lifespan of your mountain bike chain and ensure a smooth and enjoyable riding experience.
Final Words
Changing the chain on a mountain bike can seem like an intimidating task, but with the right tools and some patience, it can be accomplished by most riders. It’s important to keep the chain clean and well-maintained to ensure the longevity of your bike, and to prevent any accidents or mishaps on the trail.
Remember to consult your bike’s manual or a professional mechanic if you’re unsure about any steps in the process, and don’t forget to test ride your bike to ensure that the new chain is properly installed and functioning. With these tips in mind, you’ll be able to confidently tackle any chain replacements or maintenance needed on your mountain bike. Happy trails!
