Chain links are essential components of a bicycle’s drivetrain, allowing the chain to flex and rotate around the bike’s sprockets. However, there may come a time when you need to remove a bike chain link, whether it’s to replace a damaged link or to adjust the chain’s length. While this may seem like a daunting task, it’s actually quite straightforward with the right tools and a bit of patience. Here’s a step-by-step guide on how to remove a bike chain link.
The first step is to gather the necessary tools. You’ll need a chain tool, which is a specialized tool designed to remove and install chain links. You can purchase a chain tool at most bike shops or online. Once you have your chain tool, you’re ready to start the process of removing a chain link.
To begin, identify the chain link that you want to remove. Once you’ve identified the link, use the chain tool to push the pin that holds the link together out of the chain. Be careful not to push the pin all the way out, as this could damage the chain. Once the pin is partially out, you can use your fingers to pull it the rest of the way out. With the pin removed, you can now separate the chain link from the rest of the chain.
Identifying the Correct Link
Pinning down the correct link to remove may seem like an easy task, however, it can be more challenging than anticipated – especially if you’re a newbie in bike maintenance. Luckily, there are a few telltale signs that will help you identify the correct link for removal:
- Wear and tear: The link you need to remove will likely show signs of wear and tear, such as rust, dirt, or damage. If you notice any of these signs, it’s a good indication that this is the link that needs to be replaced.
- Chain tension: If your bike’s chain is too loose or too tight, it can put unnecessary stress on the links, causing them to wear out prematurely. To check the chain tension, simply lift the chain about an inch off the rear cog. If it’s too loose, you’ll need to tighten it by removing a link. If it’s too tight, you’ll need to loosen it by adding a link.
- Master link: Many modern chains have a master link, which is a special type of link that can be easily removed without any tools. If your chain has a master link, it will be located near one of the ends of the chain. To remove the master link, simply use your fingers to push the two halves of the link apart.
Once you’ve identified the correct link, you can proceed to the next step, which is removing the link.
Gathering Essential Tools
To successfully remove a bike chain link, you will require a specific set of tools. These tools are readily available at most hardware stores or online retailers.
Chain Tool
A chain tool is the most important tool for this task. It is a specialized tool designed to break and join bike chains. Chain tools come in different types, but the most common is the pin-pusher style. It features a small pin that pushes the chain pin out of the link.
Pliers
Pliers are also necessary for removing bike chain links. They are used to hold the chain in place while the chain tool is being used. Additionally, pliers can be used to straighten the chain pin once it has been removed.
Quick-Release Link (Optional)
If your bike chain has a quick-release link, you will not need a chain tool. Quick-release links allow you to easily disconnect the chain without using any tools. However, they are not as common as traditional chains.

Use a Chain Tool
This is the most common method for removing bike chain links. Chain tools are specifically designed to push out the chain pin without damaging the chain. To use a chain tool, simply follow these steps:
- Place the chain tool over the chain pin that you want to remove.
- Tighten the chain tool’s screw until the pin starts to move out of the chain.
- Continue tightening the screw until the pin is completely out of the chain.
Use a Hammer and Punch
If you don’t have a chain tool, you can use a hammer and punch to remove bike chain links. However, this method is more likely to damage the chain, so it’s only recommended if you’re in a pinch.
- Place the chain on a hard surface, such as a concrete floor or a vise.
- Place the punch against the side of the chain pin that you want to remove.
- Hit the punch with a hammer to drive the pin out of the chain.
Safely Removing the Chain Pins
When removing chain pins, it is important to be careful not to damage the chain. Here are a few tips to help you avoid damaging the chain:
- Use the correct tool for the job. If you’re using a chain tool, make sure that it is the correct size for your chain.
- Don’t apply too much force when removing the chain pin. If you’re using a hammer and punch, tap the punch gently to avoid damaging the chain.
- Be patient. Removing chain pins can take some time. Don’t try to rush the process, or you’re more likely to make a mistake.
| Tool | Pros | Cons |
|---|---|---|
| Chain tool | Quick and easy to use | Can be expensive |
| Hammer and punch | Inexpensive and easy to find | More likely to damage the chain |
Disconnecting the Chain Links
Chain master links, also known as quick links, are specialized links that allow you to disconnect and reconnect the chain without the need for tools. Master links consist of two hinged plates that can be manually opened and closed, making them easy to use and reusable multiple times.
To disconnect the chain using a master link, simply open the hinged plates by hand. Usually, one of the plates will have a small lever that you can press or pull to release the link. Once the link is open, you can separate the two ends of the chain and perform the necessary maintenance or repair.
Using a Chain Tool
If your chain does not have a master link, you will need to use a chain tool to disconnect the links. Chain tools come in different styles with various mechanisms for removing links. However, the process generally involves the following steps:
1. Position the chain tool over the pin connecting the links you want to remove.
2. Tighten the chain tool to apply pressure on the pin and push it out of the link.
3. Once the pin is removed, you can separate the chain into two pieces.

When using a chain tool, ensure that you carefully align the tool with the pin to avoid damaging the chain or the tool itself.
Inserting the New Chain Pin
To insert the new chain pin, first align the chain link so that the hole for the pin is facing up. Next, take the new chain pin and insert it into the hole. Push the pin in as far as it will go, using your fingers or a pair of pliers. Once the pin is fully inserted, it may be necessary to use a chain pin tool to fully seat the pin and ensure it’s properly connected.
Checking the Pin
Once the pin is inserted, it’s important to check that it’s properly seated and secure. To do this, gently pull on the chain link to make sure that the pin is not loose or moving around. If the pin is loose, it may be necessary to use a chain pin tool to further tighten the pin.
Tips for Inserting the New Chain Pin
Here are some tips for inserting the new chain pin:
| Tip | Description |
|---|---|
| Use a chain pin tool | A chain pin tool can make it easier to insert and remove chain pins. |
| Be careful not to damage the chain | When inserting the chain pin, be careful not to damage the chain or the pin itself. |
| Check the pin before riding | Before riding your bike, make sure that the chain pin is properly seated and secure. |
Installing the Master Link
To install the master link, align the two ends of the chain so that the pins are facing each other. Position the master link over the pins, with the arrows on the link facing the direction of travel.
Using a chain tool, insert the master link pins into the chain ends. Push the pins in until they are flush with the outer plates of the chain.
Once the master link is installed, it is important to check that it is properly secured. Hold the chain up to the light and ensure that there is no light visible between the master link and the chain. If there is any light visible, it means the master link is not properly secured and should be reinstalled.
Finally, use a pair of pliers to bend the ends of the master link pins flat. This will help to prevent the master link from coming loose.
Checking the Chain Length
After installing the new chain, it is important to check the length to ensure that it is the correct size for your bike. To do this, shift the bike into the largest chainring and the smallest cog. Wrap the chain around the chainrings and cogs, and then pull the two ends of the chain together.
If the two ends of the chain overlap by 1-2 links, then the chain is the correct length. If the ends of the chain do not overlap, then the chain is too short and needs to be replaced.
| Chain Length | Recommended Overlap |
|---|---|
| 9-speed | 1-1.5 link |
| 10-speed | 1.5-2 links |
| 11-speed | 2-2.5 links |
| 12-speed | 2.5-3 links |
Checking Chain Length and Alignment
Checking the chain length and alignment is crucial for a smooth and efficient drivetrain. Here are the steps to do it:
1. Shift to the Smallest Cogs
This allows the chain to be at its longest length, making it easier to determine if it’s too long.
2. Find the Ideal Chain Length
To do this, wrap the chain around the largest chainring and smallest cog without routing it through the derailleur. The ends should overlap by approximately two to four links.
3. Check Alignment
Place a ruler or straightedge along the chain, spanning several links. If the chain is aligned properly, the ruler will rest flat on all the links.
4. Adjust Derailleur Tension
If the chain is not aligned, adjust the derailleur tension by turning the barrel adjuster. Turn the adjuster clockwise to increase tension and counterclockwise to decrease it.
5. Recheck Alignment
After making adjustments, recheck the chain alignment using the ruler.
6. Secure the Chain
Once the chain is aligned correctly, use a chain tool to reconnect the ends and secure them with a master link or connecting pin.
7. Check Chain Length on & Off the Bike
- On the Bike:
Shift to the largest chainring and largest cog. The chain should be taut, with minimal slack. - Off the Bike:
With the chain removed from the bike, measure its length by wrapping it around a known reference point (e.g., a ruler or another chain). The length should be approximately the same as the ideal chain length determined in step 2.
Removing a Bike Chain Link
Unfold the master link’s outer plate to release the chain. Push the opposite inner link pin inwards and out from the opposite end. Repeat this process on the other side of the chain to disconnect the links. Use pliers to carefully remove the master link.
If your chain does not have a master link, you will need a chain tool to remove a pin. Insert the chain tool’s pin into the center of the pin you wish to remove and turn the handle to push the pin out.
Once the chain is broken, you can remove or add links as needed. To add a link, simply insert it into the open gap in the chain and push the master link’s outer plate back into place. To remove a link, repeat the process of pushing out the inner link pin and carefully disconnecting the links.
After making any adjustments to the chain length, ensure that the master link is properly aligned and fully engaged. Improperly aligned master links can cause the chain to break under load.
Tightening and Lubricating the Chain
A properly tightened chain will not slip on the sprockets and will provide smooth, efficient pedaling. To tighten the chain, turn the adjuster nuts on the rear derailleur counterclockwise until the chain is taut. Avoid overtightening, as this can put excessive stress on the chain and other components.
Lubricating the chain regularly is essential for its longevity and performance. Apply a thin layer of chain lube to the inside and outside of the chain links. Allow the lube to penetrate for a few minutes before wiping off any excess.
Specific Lubrication Points
To ensure optimal lubrication, focus on applying lube to the following points:
| Location | Reason |
|---|---|
| Inner Link Plates | To reduce friction between the plates |
| Outer Link Pins | To lubricate the contact points between the pins and inner plates |
| Roller Bearings | To minimize friction between the rollers and pins |
Testing the Chain for Smooth Operation
Before removing any links from the chain, it’s essential to test its current functionality to identify any underlying issues. Here’s how you can proceed:
- Shift into the middle gear: This provides a balanced chain tension for testing.
- Pedal forward: Rotate the cranks by hand to check for any rough spots or resistance in the chain’s movement.
- Listen for grinding or abnormal sounds: Pay attention to any unusual noises coming from the chain, as they may indicate other problems.
- Check for straight alignment: Make sure the chain is running straight between the chainrings and cassette sprockets. Any misalignment could cause issues.
- Inspect for rust or corrosion: Look for any signs of rust or corrosion on the chain, as these can affect its performance.
- Clean the chain (optional): If the chain is dirty or oily, it’s advisable to clean it before testing to eliminate any potential interference.
- Lubricate the chain (optional): Applying a light coat of chain lube can help reduce friction and improve the chain’s smoothness.
- Repeat the testing process: After any cleaning or lubrication, re-test the chain to confirm its smooth operation.
- Determine next steps: Based on the test results, you can either proceed with removing links if necessary or address any underlying issues that may have been identified.
| Chain Testing Results | |
|---|---|
| Observation | Next Step |
| Chain moves smoothly without resistance | No further action required |
| Rough spots or excessive resistance | Examine chain for wear or damage. Consider replacing the chain if necessary. |
| Grinding or abnormal sounds | Identify the source of the noise and address the underlying issue. |
| Misaligned chain | Realign the chain properly. |
| Rust or corrosion | Clean the chain and apply rust-penetrating oil. Consider replacing the chain if severely damaged. |
