Maintaining your mountain bike is essential for its longevity and smooth performance while riding. One of the most common maintenance tasks is replacing the chain. When the chain starts to wear out, it can affect the shifting and acceleration of your bike, making your ride less comfortable and less efficient. Taking your bike to a mechanic for this simple replacement can be costly, but with a few tools and a bit of knowledge, you can do it yourself.
In this article, we will guide you through the process of putting a new chain on your mountain bike. We will take you step by step through the process, highlighting key factors such as bike compatibility, chain length, and proper chain lubrication. Whether you are a newbie in mountain biking or a seasoned pro, this guide will help you save money and gain the satisfaction of working on your own bike. So, without further ado, let’s get to it.
Gather the Necessary Tools and Equipment
Gathering the necessary tools and equipment is the first and most important step in fitting a new chain to your mountain bike. You will need the following tools: A chain tool, a new chain, a pair of pliers, and a couple of quick-release links. You can purchase all these items at your local bike shop or online if you do not already have them in your toolbox.
The chain tool is the most vital tool in this process as it enables you to cut the new chain to the correct length and remove any links required. The pliers are used for bending the ends of the chain back together. The quick-release links, which link the chain together, will come in handy if you need to replace a damaged link or remove the chain for cleaning. With these tools and equipment in hand, you are now ready to move on to the next steps of easily installing a new chain on your mountain bike.

Removing the Old Chain
Removing the old chain from your mountain bike is an important step in putting a new chain on. Before beginning the process, make sure you have the necessary tools – a chain tool and pliers. Start by shifting the chain onto the smallest chainring and rear cog so it’s easiest to access.
Using the chain tool, line up the pin of the tool with the rivet on the chain and tighten it until it pushes the rivet out. Use the pliers to finish pulling out the rivet once it’s loosened. Continue pushing and pulling out rivets until the old chain is completely removed from the bike. Remember to dispose of the old chain properly and ensure that you purchase a new chain that is the correct length for your bike.
Measuring the Correct Length for the New Chain
Measuring the correct length for a new chain is an important step in the process of replacing the old chain on your mountain bike. Using a chain that is too long will not only add unnecessary weight but can also result in a slacking chain that causes damage to your bike’s components. On the other hand, using a chain that is too short can lead to inconsistent power transmission and jeopardize your safety while riding.
To measure the correct length for the new chain, you will need to wrap the chain around the largest front chainring and the largest rear cog. Then, add two links to the chain (or adjust as needed) and break the chain at the appropriate link using a chain tool. It’s essential to double-check the length before breaking the chain to ensure it fits your bike perfectly.
It’s always better to be safe than sorry when it comes to your bike’s chain length. Take your time and measure twice to get the perfect fit for a smooth and safe ride.

Connecting the New Chain
Connecting the new chain can be a bit tricky, but with the right tools and techniques, it can be done easily. Firstly, place the chain on the smallest front and rear cogs. This will create enough slack in the chain to connect it. Use a chain tool to push out the pin on one end of the chain, so that it can be inserted into the other end. Make sure that the plates are properly aligned before pushing the pin back in place.
Once the pin is back in place, use the chain tool to break the chain at the appropriate length. Check the chain’s tension by rotating the pedals with your hand, ensuring that the chain moves smoothly and without any noise. Lastly, reattach the chain to the derailleur and test the bike’s shifting. Make any necessary adjustments before taking your bike out for a test ride. By following these steps, you can easily connect a new chain to your mountain bike and get back to your next adventure on the trails.
Adjusting the New Chain for Proper Tension
After successfully installing a new chain on your mountain bike, you will need to adjust the chain tension to ensure proper shifting and avoid the chain falling off or rubbing against the derailleurs. Start by shifting your bike into the smallest chainring in the front and the largest cog in the back.
Next, use a chain tool to remove any excess links if the new chain is longer than the old one. Then, using the barrel adjuster on the rear derailleur, turn it clockwise to increase tension or counterclockwise to decrease tension until the chain moves smoothly and quietly through all gears. Make sure that the jockey wheels in the derailleur are lined up vertically under the cassette to ensure proper shifting. Finally, check the chain tension by pushing down on it in the middle of the chainstay between the chainring and cassette. The chain should not move more than 1 inch up or down. Proper chain tension will not only improve your bike’s performance but also extend the lifespan of your chain and drivetrain components.
Lubricating the New Chain for Optimal Performance
After you have successfully installed the new chain on your mountain bike, it is crucial to lubricate it properly to ensure optimal performance. Lubrication reduces the risk of your new chain rusting and wearing out prematurely, making it easier to pedal and extending the longevity of your chain.
To lubricate your new chain, you can use a bike-specific lubricant, preferably one that is water-resistant and durable. Apply a generous amount of lubricant to each link of your new chain before spinning the pedals to allow the lube to penetrate and spread to all parts of the chain. For best results, wipe off any excess lubricant with a clean cloth, and avoid using a degreaser as it can strip away too much lube, leaving your chain exposed to rust and wear. By following these simple steps, you’ll keep your mountain bike running like a well-oiled machine.

Post-Installation Checks and Maintenance Tips
Once you have successfully installed the new chain on your mountain bike, there are some important post-installation checks that you should perform. Firstly, make sure that the chain is properly lubricated before your first ride. This will ensure smoother shifting and prevent premature wear and tear. You can use a specialized bike lubricant to achieve this.
Additionally, it is important to regularly maintain your chain to ensure its longevity. Make a habit of cleaning and lubricating your chain after every other ride. Avoid using harsh chemicals to clean your chain as they can damage the chain’s links. Instead, use a gentle degreaser and a soft brush to remove any dirt or debris. Regular maintenance will not only ensure a smooth and efficient ride but also save you from costly repairs in the long run.
Verdict
Putting a new chain on a mountain bike may seem like a daunting task at first, but with the right tools and a bit of practice, it can be a quick and easy process. Proper maintenance of your bike’s chain is essential to improve its performance and extend its lifespan. By following the steps outlined in this article, you can replace your chain in no time and be back on the trails in no time.
Additionally, it’s important to remember that your chain is just one component of your bike’s drivetrain. Regular maintenance of all parts, including the cassette, chainrings, and derailleur, is crucial to keep your bike running smoothly. By taking good care of your bike, you can ensure that it will provide you with many miles of safe and enjoyable riding. So, take the time to learn how to replace your chain and keep up with regular maintenance – your bike (and your wallet) will thank you!
