To remove a bicycle chain, you'll generally either need a chain tool to push out a chain pin, or quick link pliers to undo a quick link (if your chain has one).
Methods for Removing a Bicycle Chain
There are two primary methods for removing a bike chain, depending on the type of chain you have: using a chain tool or using quick link pliers.
1. Removing a Chain with a Chain Tool (Chain Rivet Extractor)
This method applies to chains that do not have a quick link.
- Locate a chain pin: Choose a pin that you want to push out to break the chain.
- Position the chain in the chain tool: Place the chain in the chain tool, ensuring the pin you want to remove is aligned with the tool's pin.
- Tighten the tool: Carefully tighten the chain tool to push the tool's pin against the chain pin.
- Push the pin partway out: Continue tightening until the chain pin is almost completely pushed out of the outer plate, but still connected to the inner plate. Important: Do not push the pin completely out, as it can be difficult to reassemble.
- Loosen the tool and separate the chain: Loosen the chain tool. Now you should be able to easily separate the chain at the weakened link.
2. Removing a Chain with a Quick Link
This method applies to chains that have a master link, also known as a quick link or connecting link.
- Identify the quick link: Look for a differently shaped link on your chain. Quick links usually have a smooth surface and a noticeable split.
- Use Quick Link Pliers (Recommended): Quick link pliers are the easiest and safest way to remove a quick link. Insert the pliers into the quick link and squeeze the handles to separate the link.
- Alternative Method (Without Pliers): If you don't have quick link pliers, you may be able to separate the quick link by hand.
- Push the two plates of the quick link together while simultaneously trying to slide them past each other. This can be difficult and may require some force. Some tutorials suggest using a string or zip tie to hold the chain tight to make this process easier. Note: This can be difficult and may damage the quick link or even injure you. Using proper quick link pliers is strongly recommended.
- Separate the chain: Once the quick link is disconnected, you can remove the chain from your bike.
Important Considerations
- Safety: Be careful when using tools to avoid injury.
- Chain Condition: Examine the chain for wear and tear. If the chain is worn, consider replacing it rather than reinstalling it.
- Reassembly: When reassembling the chain, make sure the quick link (if applicable) is properly installed and secure or use a new chain pin with a chain tool according to the manufacturer's instructions.
- Chain Compatibility: If replacing the chain, ensure the new chain is compatible with your bike's drivetrain.
