How To Fix Your Bike Chain? (Explained)

Bike chain maintenance is a crucial aspect of keeping your bike in good working condition. A broken or worn-out chain can result in poor shifting and reduced power transfer, making riding less efficient and less enjoyable. Fortunately, fixing a bike chain is a simple process that can be done with a few basic tools.

In this article, I will show you how to fix a bike chain and get back on the road in no time.


Step 1: Identifying the problem

The first step in fixing a bike chain is to identify the problem. If your chain is making a clicking noise, jumping gears, or is visibly stretched, it’s likely time for a replacement.

If the chain is broken or has a missing link, you’ll need to replace it. If the chain is simply loose, you can usually tighten it with a chain tool.

Step 2: Gather tools

To fix a bike chain, you’ll need a few basic tools. These include:

  • Chain tool
  • Pliers
  • Ruler or Measuring Tape

It is always a good idea to keep these tools in your bike tool bag, as chain issues can spring up at any time while you are on a ride.

Step 3: Removing the chain

Use the chain tool to remove the chain from the bike. Begin by loosening the bolts that hold the chain in place and carefully separating the links. Be sure to keep track of the direction of the chain so that you can reassemble it correctly.

Step 4: Measuring the chain

Once the chain is removed, measure the length to determine how many links you need to remove or add.

To do this, wrap the chain around the largest chainring and the largest rear cog and measure the distance between the two pins that connect the chain.

Step 5: Removing or adding links

If your chain is too long, use the chain tool to remove the necessary number of links. If your chain is too short, add links using a quick link or a replacement pin and chain tool.

Step 6: Reassembling the chain

Once the chain is the correct length, reassemble it and place it back on the bike. Be sure to pay attention to the direction of the chain and make sure that the links are properly aligned.

Tighten the bolts to secure the chain in place.

Step 7: Test the chain

Finally, test the chain by shifting gears and spinning the cranks. Make sure the chain runs smoothly and there are no jumps or skips. If everything is working correctly, you’re ready to hit the road.

In conclusion, fixing a bike chain is a simple and straightforward process that can be done with a few basic tools. With a little time and attention to detail, you can keep your bike running smoothly and avoid costly repairs.

Remember to regularly maintain your bike and check the chain for wear and damage to keep it in top condition.
