Fixing a Broken Bike Chain – A Step-by-Step Guide

Riding a bike is one of the most enjoyable and healthy activities that you can do, but it can quickly become frustrating when your chain breaks.

Having to take the time to fix it may seem daunting at first, but with the right tools and knowledge, the process is relatively straightforward.

This step-by-step guide will walk you through how to easily repair a broken bike chain so that you can get back on your bike as soon as possible!

You’ll need a few supplies like pliers, Allen wrenches, and link removal tools before getting started. After gathering all of these items together, start by removing the damaged portion of the chain using either a pair of pliers or an Allen wrench.

Next, insert new links into place using either a link removal tool or needle-nose pliers. Finally, connect both ends of the chain together with master links or rivets depending on what type of fastener your bike requires.

Preparing the tools

Fixing a broken bike chain is not as intimidating as it may seem. With the right tools and a bit of know-how, you can have your bike up and running in no time.

Before you begin, make sure to gather all the necessary tools for the job – a chain breaker tool, some new chain links, and a pair of pliers or wire cutters.

It’s also helpful to have an old rag on hand to keep any grease from getting on your hands or clothes.

Removing the broken chain

Removing a broken bike chain can be a tricky task, but with the right tools and knowledge, it is possible to do it yourself. Before attempting to remove the chain, make sure you have the necessary tools such as a chain breaker tool, some spare links in case you need them, and pliers or another gripping device.

Once you have all of your materials ready, start by loosening the screws on either side of the chain that connects it to the rear sprocket and derailleur.

Then, use your chain breaker tool to break off one of the links from each end of the chain. This will enable you to slide out both ends from their respective connections without having to struggle too much.

When separating one link from another, take care not to damage any other parts in the process.

Connecting the new chain

Connecting a new bike chain can be a tricky process, but with the right tools and some patience, it can be done. First, you will need to find the correct size of chain for your bike—the number of gears on your cassette will determine this.

Once you have the proper length chain, use a quick link or master link to connect one end of the chain to the other. If using a quick link, make sure that both ends are firmly inserted into the link before closing it.

When using a master link, make sure that both ends are properly lined up before pushing them together and securing them with pliers or an adjustable wrench.

After connecting the two ends of the chain together, check that there is no slack on either side by pulling gently on each side while rotating your crankset forward.

1Finishing up

Finishing up. Once you’ve successfully completed the steps to fixing a broken bike chain, it’s time to finish up. First, hold the chain taut between your fingers and rotate the pedal backward.

This will help ensure that all of the links are properly connected. Next, take a few practice rides on your bike to make sure everything is working correctly.

If you experience any difficulties or if something doesn’t feel right, then stop riding immediately and check for any loose connections or missing pieces.

Finally, take some time to clean off your bike chain using a rag and lubricate it with a light oil or grease so that it runs smoothly in the future.

Testing the connection

Once you have finished connecting the broken links of the bike chain, it is important to test the connection before riding. To do this, start by turning the crank and pedaling backward.

This will allow you to observe if all of the links are connected properly. If any links appear loose or disconnected, then you may need to adjust them for a better fit.

Additionally, make sure that none of the pins or rivets protrude outwards as these can cause damage to other components on your bike.

Once satisfied with the connection, use a cloth or rag to wipe off any excess grease that has accumulated during the re-assembly process.

Finally, take your bicycle for a short ride and inspect it afterward for any further issues that may have arisen due to improper linking of your chain.

Reattaching the chain to the bike

Reattaching the chain to the bike is the final step in fixing a broken bike chain. It requires some patience and attention to detail, but it can be done with a few simple tools.

First, you will need to locate the master link of your chain, which is usually a small metal piece with two pins coming out of it. Remove any dirt or grime from around this link and make sure that both pins are fully seated in their holes.

Once they are ready, slide one end of the chain onto one side of your rear sprocket and then align the other end so that it lines up perfectly on top of the other side.

Make sure that all links are properly seated and tightly secured before proceeding further. Finally, press down on each pin until it clicks into place and you hear an audible “snap” sound indicating that the link is now secure.


Adjusting the tension

Adjusting the tension of your bike chain is the last step in fixing a broken bike chain. To do this, you’ll need to use a tool called a derailleur hanger alignment gauge, which can be found at any cycling store or online.

Start by shifting your bicycle into its lowest gear and then loosening the cable anchor bolt on the rear derailleur. Next, turn the barrel adjuster on the end of your shift cable until it is just barely loose enough for you to move one link of your bike chain with your fingers.

Now, hold onto that link and pull up gently while turning the barrel adjuster clockwise until there is no more slack in the chain. Finally, tighten down both bolts on the rear derailleur and test out your new bike chain by pedaling forward to make sure everything shifts correctly and you have achieved optimal tension.

Lubricating the chain

Once you have reattached the chain, it’s time to lubricate the links. This will help keep the chain moving smoothly and reduce wear on its components.

To begin, apply a few drops of quality bike oil or lube to each link along the chain. Start at one end of the chain and work your way around until you reach the other side.

Use a clean rag to wipe away any excess oil or lube from the outside of the chain.

Common Questions Answered

1 What happens if my bike chain breaks?

If your bike chain breaks, it can be a major inconvenience as it will render your bike useless until it is fixed. Fortunately, the problem can usually be solved relatively quickly and easily with some basic tools.

To repair a broken bicycle chain on the road, you will need to have a bicycle chain tool as part of your multi-tool set or purchase one separately.

You also need to have a spare quick-link which is basically just a connector that allows you to join two ends of the chain together.

Once you have these items in hand, you can use the chain tool to remove any broken links or pins from the damaged section of the chain and then connect both ends of the repaired section using the quick link. This should allow you to ride home safely until you are able to take your bike for professional repairs at a local shop if necessary.

2 What is a chain break for a bicycle?

A chain break is an essential tool for any cyclist, as it allows you to easily disconnect the chain from your bike with minimal effort.

This can be done in a couple of ways depending on whether your bike’s chain has a master link or not. If it does have a master link, you simply use the appropriate size master link pliers to open up the clip and remove the chain.

If there isn’t a master link, then you will need to use a dedicated chain-breaking tool. Before beginning this process, it’s important that you shift your gear system down so that your chain is on the smallest sprocket and smallest front ring – this ensures that when you disconnect the two ends of the chain they won’t be under tension and makes them much easier to separate.

3 Do bike chains break easily?

Bike chains are a vital part of the cycling experience, as they help to ensure that your bike runs smoothly and safely. While it is not common for bike chains to break easily, it can happen if the chain gets hit hard enough with something like a rock or other object.

This type of impact damage can be difficult to repair compared to when a chain breaks due to wear and tear over time. It is important to inspect your bike regularly for any signs of wear or damage so that you can replace any worn parts before they cause further problems. Additionally, always make sure that your bike’s drivetrain is properly lubricated so that everything moves freely and efficiently without putting extra strain on the chain or other components.

4 How much force does it take to break a chain?

The amount of force it takes to break a chain depends on several factors, including the type of chain and its intended use. Generally speaking, most 9-speed to 12-speed chains and even some track chains will have a breaking strength between 8000N (International Standard) and 10,000N (German Standard).

This means that if you apply enough force in excess of these standards, the chain is likely to snap or break. However, it is possible for some chains to exceed these standards; meaning they may require more than 10,000N of force before they break.

For example, certain mountain bike chains are designed with extra strength so they can withstand greater forces when riding over rough terrain. Ultimately, the best way to determine how much force your specific chain requires before it breaks is by having it tested under controlled conditions by an experienced cycling expert.

5 Is it normal for bike chains to fall off?

The drivetrain of a bike consists of several components, including the chain, crankset, cassette, and derailleurs. All of these parts are secured together with screws or bolts.

If any of these screws or bolts become loose over time due to wear and tear from riding, then the entire drivetrain can shift around when you’re pedaling.

This can cause the chain to come off as it moves around too much for the derailleur to keep up with it. To prevent this from happening, regular maintenance should be done on your bike to make sure all screws/bolts are tightened properly so that nothing shifts while you’re riding.

Final Words

Finally, take some time to clean off your bike chain using a rag and lubricate it with a light oil or grease so that it runs smoothly in the future.

Finally, tighten down both bolts on the rear derailleur and test out your new bike chain by pedaling forward to make sure everything shifts correctly and you have achieved optimal tension.
