how to fix a bike chain

If you like to fix a broken chain, you have to use the chain tool. It has built and compact into some common multi-tools same as the one shown. You have one in your multi-tools which do not know what it for is.

You can repair the chain in your home by using pliers, or a hammer. Though chain tools are easier, it is truly the only way to the street.

How Do Chains Break?

The normal procedure is by pedaling total force at the same time which you like to shift from the front derailleur.

Other breaks I noticed caused by a collection of apparently 1 in a million happenings. I have noticed more such cases that I think if you ride long enough 1 in a million may happen still.

A nail gets thrown up by the front wheel and lodging in the chain after that receiving cranked athwart the sprocket.

How Do Chains Work?

Each chain is held at the same time by a steel peg or pin. By the chain tool you may push in and out the pins, permit you to add or remove links. On bike having derailleurs it has more links which you can remove except a problem.

One single bike has more slack in the chain to eliminate the link. You have to take some links out of the old chain or buy a new one.


To fix the chain, you have to use a chain tool. They are built and compact in many multi-tools like one shown. You can use one or multi tool to do your task. You can repair a chain in your home with pliers and a hammer. But a chain tool is easier and the only option to use in the street.

Step 1: What You Need

To mend a broken string all, you will need is a series tool. These are streamlined and built into several common multi-tools such as the one revealed. You might even have one in your multi-tool that you even knew what it was too!

In-home in your garage it is possible to fix a string with only a hammer and pliers, but a series tool is more straightforward and the only choice on the road.

Step 2: How Do Chains Break?

The most usual way is by merely pedaling full force in precisely the same time that you’re altering your front derailleur. Other fractures I have noticed were caused by an assortment of apparently one-in-a-million occurrences. However, I have seen enough of these cases that I suppose if you ride long one-in-a-million still occurs — matters like a nail becoming thrown up by my front wheel and accommodation at the series, then becoming cranked throughout the sprocket.

Step 3: How Do Chains Work?

Using the series tool (or a hammer) you can push and push at the pins, letting you remove or attach hyperlinks. On bicycles, with derailleurs, you will find enough additional links which you can get rid of a few with no problem. On a single-speed bike, you likely won’t have enough slack in the series to get rid of a connection, and you will want to borrow some hyperlinks via an old set or buy a new one.

Step 4: Your Chain Just Broke, Now What?

Are you currently wearing beautiful clothing that you take care of? Come back after having your jeans, and we’ll repair it then. Fixing a series is the dirtiest task there’s on a bicycle.

Step 5: Look at the Chain

Ok, you are back and ready to proceed. Flip your bicycle over so that you may reach the series more readily.

Have a peek at the two ends that are broken. One end is damaged and has to be eliminated. What you may do is to eliminate two sections of the string in the end. You have to eliminate two sections rather than one due to the two varieties of section alternative. If you merely eliminate 1 section, you cannot re-attach it.

Set the chain to the groove at the series tool in the place that you need to disconnect.

Step 6: Separate the Chain

Twist the screw thread on the string tool to begin pushing the pin from the string. Be cautious to maintain the bolt onto the string tool lined up using the flash onto the rope. Sometimes they prefer to slide around a little bit.

Do not push the pin all the ways out! Only drive it only far enough so that the series comes apart (see picture). You must leave the final bit of this pin in the series, so it is possible to push it back later.

If you would like to do this with no string tool: drill a hole into a sheet of timber and set the pin that you would want to eliminate over the pit. It is tricky because you don’t need to knock it out all the ways.

Step 7: Re-attach the Links

OK, feed the string back on your sprockets. It will help a lot when you’ve got a buddy who will hold both ends in place at the same time you reattach them.

Use the string tool to push the pin in. Here is the hardest part to maintain the instrument lined up using the trap. Note: if you’re putting on a brand-new chain here, several new chains include a particular link which produces the first-time setup potential without pushing any hooks in.

Step 8: Work It Loose

When the pin is in, the connection you directly attached will be rigid. Work it back and forth until it loosens enough to bend around the gears.

Have a peek at your palms and feel happy. You’ve done something real now.

Step 9: Reuse

If you were only putting on a brand-new chain in the comfort of your house, now have an old used string to reuse! As you know how to get rid of hyperlinks and reattach the sections, you may use a part of the old series for a cable to lock your chair on your bicycle. This is quite handy in urban places.


You may even create yourself a bicycle chain bracelet or an earring. You will want a reasonably large piercing and a delicate ear to acquire that stud.

As you are on the road, your chains break:

  1. You are wearing very good clothes. You like to take care of it. Best is to lock the bike and take a bus to go. Then come back with your old jeans and fix it. Fixing the chain is the dirtiest job for the bike.
  2. You are back and prepared to go. Flip the bike over and you may get the chain more easily.
  3. See the 2 broken ends. You have to remove the 2 segments of the chain as the 2 kinds of segments alternate. As you alter 1 segment, you fail to reattach it. Put the chin to the groove in the chain tool you like to disconnect at the spot. If you like to replace a worn but nonbreakable chain, you can do it again.
  4. Move the screw in the chain tool to begin pressing the pin out of the chain. Be cautious to put the pin on the chain tool added with the brooch of the chain. It may sometimes slip around a bit.
  5. Do not press the pin all the way. Press it more enough as the chain comes individual. You have to keep the last bit of the pin with the chain as you have the option to press it back next time.
  6. Feed the back of the chain to your sprockets. It helps more as you have a friend who catches 2 ends in place as reattach them.
  7. Utilize the chain tool to press the pin back in. The trickiest part is to preserve the tool added to the pin. Note: if you like to put a new chain, many new chains appears with a special link which makes the 1st time installation possible without pressing any pin.
  8. If the pin is in, the link may be stiff. Act it back as well as forth, as long as it lessens more to bend.
  9. Look at your hand, and you are the product for your job. You have done something great for today.
