A broken chain is one of the most common bike repair issues. Whether you’re a beginner or a seasoned cyclist, it’s important to know how to fix your chain in case of an emergency. In this article, we’ll discuss the basics of chain repair and provide step-by-step instructions for fixing a broken chain.
What Is a Chain?
A bike chain is a metal link that connects the front sprocket to the rear sprocket. The chain transfers power from the pedals to the rear wheel, allowing the bike to move. It’s essential for any ride, so it’s important to know how to diagnose and fix a broken chain.
Common Chain Problems
There are several common chain problems that can cause a broken chain. The most common causes are worn out parts, misaligned parts, or a bent chain link. It’s important to diagnose the problem before attempting to fix it.
Worn Out Parts
Worn out parts are one of the most common causes of a broken chain. When a chain is worn out, it’s more likely to break. Over time, the metal links in the chain become worn and weak, and they can snap under the pressure of pedaling.
Misaligned Parts
Misaligned parts can also cause a broken chain. If the front and rear sprockets are not aligned properly, the chain can become twisted and snap. This can happen if the bike’s drivetrain is not properly adjusted.
Bent Chain Link
A bent chain link is another common cause of a broken chain. If a link is bent or damaged, it can cause the chain to break. This can happen if the bike is ridden over rough terrain, or if the chain is not properly maintained.
How to Fix a Broken Chain
Once you’ve diagnosed the problem, it’s time to fix the broken chain. To fix a broken chain, you’ll need to have the right tools and supplies. Depending on the severity of the problem, you may need to replace the entire chain or just the broken link.
Replacing the Entire Chain
If the chain is severely worn or misaligned, it’s best to replace it. To do this, you’ll need to remove the old chain, clean the drivetrain, and install the new chain.
Step 1: Remove the Old Chain
To remove the old chain, use a chain breaker tool to remove the broken link. Carefully remove the link from the chain and discard it.
Step 2: Clean the Drivetrain
Once the chain is removed, use a degreaser and rag to clean the drivetrain. This will help ensure that the new chain is installed properly.
Step 3: Install the New Chain
Once the drivetrain is clean, use a chain pin tool to install the new chain. Make sure that the chain is properly aligned and that the pins are inserted correctly.
Replacing a Link in the Chain
If the chain is not severely worn or misaligned, you may be able to replace just the broken link. To do this, you’ll need to remove the broken link, clean the chain, and install a new link.
Step 1: Remove the Broken Link
Use a chain breaker tool to remove the broken link. Carefully remove the link from the chain and discard it.
Step 2: Clean the Chain
Once the broken link is removed, use a degreaser and rag to clean the chain. This will help ensure that the new link is installed properly.
Step 3: Install the New Link
Once the chain is clean, use a chain pin tool to install the new link. Make sure that the link is properly aligned and that the pins are inserted correctly.
