Remove the Old Chain from Your Mountain Bike
Removing the old chain from your mountain bike is a crucial step in replacing it. To do this, you will need a chain tool, which can be purchased at any bike shop or online. First, shift your bike to the smallest chainring and smallest cog on the rear wheel. This will ease the process of removing the old chain.
Next, locate the master link on your chain. It is usually a different color or has a special shape compared to the other links. Use the chain tool to push out the pin holding the master link in place. Once the master link is removed, you can pull the old chain off your bike. Be careful not to lose any small parts or pins that may fall off during the process. With the old chain off, you can now move on to the next step in replacing your mountain bike chain.
Determine the Correct Length of Your New Bike Chain
When it comes to replacing your mountain bike chain, it is essential to determine the correct length of your new bike chain. This is vital as using the wrong chain length can cause several issues, including weakening the drivetrain and premature wear on the chain, gears, and cassette.
The easiest way to determine the correct length of your new bike chain is to count the number of teeth on your bike’s largest chainring and the smallest cog on the cassette. Once you have the numbers, add them together and subtract one from the total. This number will give you the ideal chain length for your mountain bike. It is always advised to measure your old chain’s length to ensure accurate measurements and avoid any inconvenience while replacing the new chain.

Prepare Your Bike for the Installation of Your New Chain
Before you install your new mountain bike chain, you need to make sure that your bike is prepared for the installation. This means checking the condition of the cassette, derailleur, and chainrings, as well as cleaning the bike and removing any debris that may have accumulated on the chain.
To check the condition of the cassette and chainrings, look for any signs of wear or damage. If you notice any worn or damaged teeth on the cassette or chainrings, it’s best to replace them before installing a new chain. Additionally, check that the derailleur is properly adjusted and that the jockey wheels are clean and functioning properly. Once you’ve inspected your bike, clean it thoroughly, paying special attention to the chain, and make sure that the rear wheel is properly aligned before installing your new chain.
Install Your New Bike Chain onto Your Mountain Bike
Installing a new chain on your mountain bike can be a bit tricky, but with these simple steps, you can do it with ease. First, you need to open the chain link that connects the chain ends. For this, you can use chain pliers or a chain tool. Once the link is open, thread the new chain over the bike’s drivetrain, making sure that the chain runs smoothly over the rear cassette and front chainring.
Next, connect the two ends of the chain by putting them through the open link. Make sure that the ends are facing the correct way – the smaller end of the link should face towards the bike’s rear. Then, use the chain tool to press the link back together until it clicks in place. Finally, give the chain a spin to check that it moves freely and doesn’t skip gears. And there you have it – a brand new chain installed on your mountain bike!
Check for Proper Tension and Adjust if Necessary
Once the new chain is in place, you need to make sure it is properly tensioned. First, shift your bike to the smallest cog and chainring. Then, push down on the pedal to create some slack in the chain. Ideally, you should be able to lift the chain 1-2 centimeters away from the chainring without it slackening.
If the chain is too loose, the bike will not shift gears smoothly and the chain may even come off during a ride. To adjust the tension, you need to use your rear derailleur to move the bike’s wheel and the cassette forward or backward. Simply turn the barrel adjuster on your derailleur until the desired chain tension is achieved. After making adjustments, ensure that the gears can shift smoothly across the entire cassette while the chain remains at the correct tension.

Maintenance Tips for Your Newly Replaced Bike Chain
After successfully replacing your mountain bike chain, it’s important to keep it in good condition to ensure a smooth and safe riding experience. Here are a few maintenance tips to follow once you’ve replaced your bike chain:
The first step is to properly lubricate your chain. A well-lubricated chain not only runs smoothly but also helps prolong its lifespan. Make sure to use a high-quality chain lubricant and apply it generously to the chain, making sure to cover every link. Additionally, be sure to regularly clean your chain to remove any grit or dirt that may accumulate and cause damage. Keeping your chain clean and lubricated will help prevent rust and corrosion and keep your bike running smoothly for longer.
Another important aspect of maintaining your newly replaced bike chain is to check its tension regularly. You want the chain to be tight enough so that it doesn’t come off, but not so tight that it puts undue stress on the chain, cassette or derailleur. To check the tension, use a chain tension gauge or simply flex the chain with your fingers to create a gap, which should be no more than 1/2 inch in length. By following these simple maintenance tips, you can ensure the longevity of your newly installed bike chain.
Conclusion
Replacing a mountain bike chain is essential to maintain the longevity of your bike and ensure a safe ride. With the right tools and a little bit of patience, it’s a straightforward process that can be done in a short amount of time. By following the steps outlined in this article, you’ll be well on your way to a smoother and more efficient ride.
As with any maintenance task, prevention is key. Regularly cleaning and lubricating your bike chain can extend its lifespan and potentially save you from having to replace it prematurely. Additionally, taking note of any abnormal wear or skipping in the chain can signal the need for a replacement. By staying on top of your bike’s maintenance, you can enjoy a safer, smoother, and more comfortable ride.
