No matter how familiar you are with bicycles, changing or repairing a bike chain is an essential task that all cyclists must learn to do. While it may be a difficult task, with the necessary tools and techniques, anyone can repair or replace a bicycle chain. Knowing these techniques may even save a cyclist from a potential accident or breakdown. In this article, we will provide an overview of how to change or repair a bike chain, discuss the tools needed, and cover a few maintenance tips.

What is a Bicycle Chain?

A bicycle chain is a metal link connected to the pedals via a derailleur. As a cyclist pushes down on the pedals, they rotate the chain which in turn makes the rear wheel spin and thus propels the bike forward. It’s crucial that the links of a bike chain are correctly aligned and tensioned in order for the bike to operate properly.

DIY Bike Chain Repair and Replacement Tools

Before starting, it’s important to know exactly what tools are needed for a successful bike chain repair or replacement. Here are the basics:

  • Chain breaker tool
  • Pedal wrench
  • Slot screwdriver
  • Chain lube
  • Replacement bike chain

Repair or Replace a Bike Chain

Check Chain’s Condition

In order to determine whether to repair or replace a bike chain, check the condition of the links. If the chain is too worn or rusty, replace it. If it appears to be in good shape, you can attempt to repair it.

Separate Chain

Remove the chain by using a chain breaker tool to push out one of the pins. This will allow you to take off the chain from the derailleur.

Lubricate Chain

The chain should always be lubricated so that it operates smoothly and efficiently. Be sure to use a suitable chain lube for the chain type. Apply the lube to the chain by dripping it on the inner and outer side of each link.

Rejoin Chain

After lubricating the chain, push the pin back into place with a chain breaker tool. Make sure that all of the links are properly aligned and tensioned.

Repetitively Move Chain

In order to ensure that the chain is correctly placed, repetitively move it several times to make sure that it is properly aligned and tensioned.

Check Tightness

Once the chain has been correctly reattached, check the tension by pushing down on the chain with your hand. To ensure safety, check the tension several times.

Maintenance Tips

Clean Chain Regularly

By regularly cleaning the chain, you can ensure that it remains in good condition and is free of dirt, grass clippings, and other debris.

Check Chain Tension

Periodically check the tension of the chain to ensure that it is properly tensioned. If it is too tight, it can cause the chain to stretch, which in turn could cause riding problems.

Replace Chain Regularly

In order to maintain peak performance and safety, it’s recommended to replace the chain every 2500-3000 miles. This will help ensure that the chain is in good condition.
