1. Understahnding Chains on Bikes

Understanding the parts of a bike chain is important before we start the repair procedure. Inner and outer plates, rollers, and pins make up a bicycle chain. The front chainring and the rear cassette are connected by a loop made of links, which enables the bicycle to be moved by the force of the pedals.

A chain breaker tool, sometimes referred to as a chain splitter or chain tool, is an expert tool used to remove and replace chain pins from a bicycle chain. To remove the pins holding the chain links together, it comprises a handle with a tiny pin or screw. The chain breaker tool is necessary for fixing a broken chain or modifying the length of the chain when necessary.

Replacement Chain Links

Bike Chain Half Link

Also known as master links or fast links, replacement chain links are tiny connections that make it simple to connect or detach the ends of a bicycle chain. Depending on the style of the chain, they can be standard master links or modern fast links. When a chain breaks or needs adjusting, you can rejoin it with a replacement chain link without using a chain breaker tool.

Bike chain oil

Bike chain oil

Commonly referred to as chain lubricant, is a unique kind of lubricant created especially for bicycle chains. It is available in a variety of formulas, including as wet and dry lubricants. To lessen friction between the bike chain’s moving components, including the rollers and pins, lubricant is placed on the chain. This increases the chain’s life makes sure smooth gear shifting, and lowers chain wear and tear

Dusting Cloths

Rag or cloth

Dusting Cloth

A rag or cloth is a simple piece of fabric that is used for washing and cleaning. It is used to clean the bike chain to get clear of any particles, dirt, or old lubrication in the context of bike maintenance. It’s important to use a rag to remove extra particles and dirt from the chain before applying fresh chain oil.



Long Nose Pliers

Pliers are multipurpose hand tools that can be used to hold, adjust cut, or take items. Pliers are useful for making small changes or straightening broken chain links while repairing a bike chain. It’s important to use care when using pliers on the chain to avoid further harm.

Every biker should keep this equipment and supplies on hand since they enable you to perform simple maintenance and repair procedures on your bike chain, ensuring that it performs properly and stays in good working condition for a longer period of time. Cycling can be smoother and more enjoyable if your bike chain is regularly inspected, cleaned, and lubricated.

3. Safety First

Safety should always come first when repairing bikes. To prevent it from tipping over while you work on it, place your bike securely on a stand or other surface. To protect yourself from any potential dangers put on the proper safety equipment such as gloves and safety glasses.

4. Identifying the Issue

Finding the source of your bike chain’s issue is the first step in repair. A broken chain, a bent link, or a chain that has disconnected from the cassette or chainring are common problems.

5. Removing the Chain

Before any repairs can be made if your chain is broken, it must be taken off. To remove one of the chain pins and separate the broken link from the chain, use the chain breaker tool.

6. Fixing a Bent Link

If a link is bent, use pliers to carefully straighten the broken link. To prevent causing more damage, be gentle.

7. Reconnecting the Chain

It’s time to reconnect the chain after the problem has been fixed. Use the chain breaker tool to drive the pin back into place after inserting the replacement chain link through the ends of the chain.

8. Checking Chain Tension

Smooth riding and gear shifting depend on proper chain tension. Check the chain tension on your bike, and if necessary, adjust it to the proper setting.

9. Lubricating the Chain

A properly lubricated chain guarantees top performance and lengthens its life. To avoid dirt buildup, apply a suitable chain lubricant and wipe off any excess.

10. Inspecting Gears and Chainrings

While repairing the chain, take the opportunity to inspect the gears and chainrings for any signs of wear or damage.  If they need to be replaced, do so to ensure easy gear shifting.

11. Test Ride

Take a short test ride before hitting the road to make sure your bike chain is working properly and that the repairs were successful.
