Removing a bike chain generally involves either using quick-link pliers or pushing out a chain pin with a chain tool, depending on the type of chain.
Here's a breakdown of how to remove a bike chain, covering both quick-link and traditional pinned chains:
Removing a Chain with a Quick Link:
-
Identify the Quick Link: Look for a special link that has two plates held together with slightly protruding pins, often with a different finish. This is the quick link.
-
Use Quick Link Pliers (Recommended): Quick link pliers are designed to safely open the quick link. Insert the jaws of the pliers into the pins of the quick link and squeeze. This will separate the link.
-
Remove by Hand (Without Pliers - More Difficult): If you don't have quick link pliers, you can sometimes remove the quick link by hand. Position the quick link so the connecting plates are running horizontally. Try to push the two plates together towards the centre, which will slacken the tension and allow you to slide one plate free. This can be very difficult and may require some fiddling.
-
Separate the Chain: Once the quick link is open, simply separate the chain at that point.
Removing a Chain with a Chain Tool (Traditional Pinned Chain):
-
Position the Chain Tool: Place the chain on the chain tool so that one of the chain pins aligns with the driving pin of the tool.
-
Push Out the Chain Pin: Tighten the tool's handle to push the driving pin against the chain pin. You only need to push the pin partially out, not all the way. Pushing it all the way out can make reassembly difficult. Aim to have the pin still held by the outer plate.
-
Break the Chain: Once the pin is partially pushed out, you should be able to easily bend the chain at that point and separate the link.
Important Considerations:
- Chain Wear: If your chain is worn, consider replacing it rather than just removing it for cleaning and re-installing.
- Compatibility: Make sure your new chain (if replacing) is compatible with your bike's drivetrain (number of speeds).
- Quick Link vs. Pin: Determine whether your chain uses a quick link or needs to be broken with a chain tool before you start.
- Chain Tool Quality: A good quality chain tool will make the process much easier and safer.
