The Ultimate Guide to Fixing Bike Chains: Essential Tool Required


Steps To Fixing A Bike Chain

Bike chains are an essential component of a bicycle’s mechanism, and like any other part, chains may wear out or break. If this happens, don’t worry, repairing a bike chain is relatively easy, and you don’t need to be a professional mechanic to fix it.

Here are the steps to fix a bike chain.

Step 1: Inspect The Chain

The first step in fixing a bike chain is inspecting the chain for damage. Look for visible signs of wear and tear, such as rust or corrosion, bent links, or damaged rollers. Damaged chains can be unsafe to use, and if they are broken, they can result in injury.

Step 2: Removing The Chain

Once you have inspected the chain and identified the problem, the next step is removing the chain from the bike. Removing the chain allows you to repair it more easily and check other parts of the bike. To remove the chain, use a chain tool, and push the pin through the link to break the chain apart.

Step 3: Repairing The Chain

After removing the chain, check to see if you can repair it or if it needs replacing. If it’s repairable, the most common issue is a stuck link, which can be fixed by using pliers to wiggle the link back and forth until it moves.

If the chain is rusted or corroded, apply lubricant and let it sit overnight. The next day, use a wire brush to clean the chain thoroughly.

Step 4: Reinstalling The Chain

With the chain repaired, it’s time to reinstall it on the bike. Reinstalling the chain requires lining up the chain with the gears, so it is crucial to take care when doing so. Use a chain tool to push the pin back through the link, and then apply a small amount of lubrication.

Step 5: Testing The Chain

After reinstalling the chain, it’s essential to test that it is working correctly. Shift through the gears and test the chain’s tension, making sure it isn’t too tight or too loose. Lubricate the chain regularly to avoid future issues.

By following these steps, you can fix your bike chain and save money on professional repairs. However, if you’re unsure how to fix your bike chain, it is best to take it to a professional mechanic to avoid causing further damage.
