Mountain biking is a popular outdoor activity that can be enjoyed in various terrains and environments. However, like any mechanical machine, mountain bikes can experience wear and tear over time, especially on its chain. A broken or worn-out chain can affect your bike’s performance, making it difficult to pedal or shift gears. As such, knowing how to replace your mountain bike chain is an essential skill for every rider.
In this article, we will guide you through the process of putting a mountain bike chain on step-by-step. Whether you’re a novice rider or a veteran, our guide will provide you with the knowledge and skills to fix your bike’s chain effortlessly. So, grab your tools, let’s get started!
Gather the Necessary Tools and Materials
Before attempting to put a mountain bike chain on, it is important to gather all of the necessary tools and materials. This will ensure that the process goes smoothly and the chain functions properly once it is in place. The tools needed include a chain tool, pliers, a cassette tool, a chain whip, and a wrench that fits the bike’s axle nuts.
In addition to the tools, it is important to have a new chain that fits the bike. It is recommended to purchase a high-quality chain, as it will last longer and provide better performance. It is also helpful to have a cleaning tool, such as a degreaser and brush, to clean the chain and cassette before installing the new chain. Gathering these tools and materials before starting the process will help to make the task easier and more efficient.

Remove the Old Chain from Your Mountain Bike
To replace your mountain bike chain with a new one, you need to first remove the old chain. This will require some basic tools such as a chain tool and a pair of pliers. Start by shifting your bike into the smallest chainring and the smallest rear cog. This will create slack in the chain, making it easier for you to remove it.
Next, use the chain tool to break the chain. Turn the chain tool handle in a clockwise direction to push the pin of the link all the way out. You may need to use a pair of pliers to completely remove the pin. Once the pin is out, separate the chain from the bike. If you plan to reuse the chain, lay it on a clean towel and inspect it for wear. If the chain appears damaged, it is best to replace it.
Determine the Correct Length for Your New Chain
Before you jump into putting on a new chain, it’s crucial to determine the correct length for your bike. Using the wrong length can cause significant issues like skipped gears, chain tension, and added stress on the drivetrain.
The simplest way to find the correct length is by measuring the old chain. If you don’t have the old chain, you can still find the length by sizing based on the amount of chain wrap. Wrap the chain around the largest chainring and cog without going through the derailleur. Then, add two links to the length. This is the length you need for your bike. Keep in mind that different types of bikes require different chain lengths, so double-check your bike’s specifications before purchasing a new chain.

Thread the New Chain Through Your Rear Derailleur
Once you have removed the old chain, it’s time to feed the new chain through your rear derailleur. The derailleur is responsible for shifting your gears smoothly, so it’s essential to ensure that the chain is threaded through it correctly.
Start by looping the chain over the smallest cog on your rear wheel. Then, thread the chain through the rear derailleur’s lower jockey wheel, which will be closer to the ground. Lastly, thread the chain through the upper jockey wheel, which should be positioned towards the top. Make sure that the chain follows the normal path and doesn’t cross over itself in between the lower and upper jockey wheels. With the new chain threaded correctly, you can now move on to the next step of attaching it to the bike’s crankset.
Connect the Chain Using a Chain Tool
Once you have made sure that your chain fits the bike and is properly sized, the next step is to connect the chain using a chain tool. A chain tool is a small, handheld device that makes it easy to remove or install chain links. In essence, it works by pushing chain pins in or out of the chain links to create the exact length of chain required for your bike.
To begin, you will need to properly position your chain on the chain tool. To do this, you should place the chain in the grooves of the tool, and use the tool to push a pin through the chain. Once you have done this, you can connect the two ends of the chain and use the tool to push the pin back into place. The end result should be a connected chain that is properly sized and ready to use on your mountain bike.
Adjust the Tension and Shifting on Your Bike
Once you have successfully placed the chain on your mountain bike, it’s important to adjust the tension to ensure it is neither too tight nor too loose. To check the tension, lift the bike’s rear wheel off the ground and spin the pedals backward. If the chain looks too tight, release some tension by loosening the rear axle nuts and sliding the wheel backward slightly. On the other hand, if the chain appears too loose, tighten the rear axle nuts and move the wheel forward. Make sure that both sides of the wheel are adjusted equally to avoid any chance of the wheel being misaligned.
After adjusting the chain tension, it is essential to check the shifting as well. Shift your bike into different gears to check if the chain is running smoothly between each gear. If the chain is struggling to shift properly, it may need extra lubrication. Make sure to add a few drops of chain lube to the chain and shift through the gears a couple of times to spread the lube evenly. If the issue persists, it may be best to take your bike to a professional mechanic to diagnose and fix the problem.

Test Ride and Troubleshooting Tips
After you’ve successfully put on your mountain bike chain, it’s important to take it for a test ride to ensure everything is running smoothly. Start off with a few gentle pedal strokes and shift through all your gears to make sure the chain is shifting smoothly. If you notice any skipping, hesitation, or noise while shifting, you may need to make some adjustments.
If you do run into any issues, try adjusting the derailleur’s limit screws or cable tension. It’s also a good idea to double-check that the chain length is correct and that it’s properly lubricated. Don’t hesitate to reach out to a professional mechanic if you’re struggling to troubleshoot any issues. With a little bit of patience, you’ll have your mountain bike running like new with a brand new chain.
Final Thoughts
Putting a mountain bike chain on can seem like a daunting task at first but with a little bit of patience and practice, it can become a quick and easy process. The key to success is to take your time, use the correct tools, and follow the steps in the right order.
Remember to clean your chain before putting it on and ensure that it is the correct length for your bike. Use a chain breaker to remove any excess links and avoid damaging the chain or derailleur. Lastly, make sure the chain is lubricated and properly tensioned to ensure a smooth and efficient ride. By following these simple steps, you will be able to put a mountain bike chain on like a pro in no time!
