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.

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.
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.
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.
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.
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.
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.
