Changing the chainring on your mountain bike is not only a common maintenance task but also an effective way to optimize your riding experience. A worn-out or inappropriate chainring can lead to inefficient power transfer and even damage your transmission system. For that reason, it’s essential to know how to properly change the chainring.
In this step-by-step guide, we’ll cover everything you need to know to easily change the chainring on your mountain bike. Whether you’re a seasoned cyclist or a beginner, the following instructions will help you upgrade your bike’s performance and extend its longevity. So, grab your tools and let’s get started.
Assess Your Current Chainring and Gear Ratio
Before changing the chainring on your mountain bike, it is essential to assess the current chainring and gear ratio accurately. The chainring’s size determines the number of teeth, and it is essential to note that the chainring size also impacts the gear ratio. The larger the chainring size, the faster the gear ratio, and the harder it will be to pedal uphill.
To assess your current chainring and gear ratio, you need to inspect your bike’s existing chainring. The chainring should feature numbers indicating the number of teeth on the chainring. Note these numbers down to find a replacement with the same number of teeth. Alternatively, if you seek to change your gear ratio, opt for a smaller or larger chainring. By accurately assessing your current chainring and gear ratio, you can easily find a suitable replacement chainring and ensure comfortable and efficient operation of your mountain bike.

Gather the Necessary Tools and Materials
Before you start changing your chainring on a mountain bike, there are specific tools and materials that you need to gather beforehand to make the process easier. You can’t proceed with the task without these necessary items, so it’s essential to have them on hand.
Firstly, you’ll need a set of Allen keys with varying sizes to remove the bolts on the chainring. Depending on your bike, you may also need a chainring wrench specifically designed for removing chainrings. Additionally, you’ll need a chainring of the desired size to replace the old one, compatible with your drivetrain. Finally, it’s always useful to keep a lubricant and a cloth handy to clean and maintain your drivetrain after changing the chainring. Once you’ve got everything you need, you can proceed to the next step, confident that you won’t face any hurdles during the process.
Remove Your Current Chainring
The process of changing a chainring is relatively simple, and the first step involves removing your current chainring. To do this, you’ll need to start by first removing the bolts that are holding the chainring in place. Before attempting to remove the bolts, ensure that you have the right size and type of tool. The most common tool used for removing the bolts is a hex key or Allen wrench.
Once you have the right tool, turn the bolts counterclockwise until they come loose. You’ll need to keep turning each bolt until there is enough space to slide your chainring off the crankset. Be sure to set aside the bolts in a safe place where you won’t lose them. Gently slide off the old chainring and inspect it for any damages before tossing it away. With the old chainring removed, you’ll be ready to install your new chainring, which is the next step in this process.

Install the New Chainring
Once you have removed the old chainring, it is now time to install the new one. Start by ensuring the new chainring matches the specifications of your bike’s crankset. Remove any burrs and grime from the fixing bolts, and thread them into the holes on the chainring. Tighten the bolts in a cross pattern and to the manufacturer’s recommended torque specification. This is important, as an incorrect torque can cause damage to the chainring or the crankset.
Next, adjust the chainring’s position on the crankset so that the teeth line up with the bike’s chain. Check for any rubbing or misalignment by hand-rotating the crankset without the chain. Make any necessary adjustments to ensure the chainring spins smoothly and cleanly. Finally, test the bike’s shifting in the front and make fine-tune adjustments if required. Congratulations, you have now successfully installed a new chainring on your mountain bike!
Adjust the Front Derailleur
Once you’ve successfully removed the old chainring and installed the new one, the next step is to adjust the front derailleur to ensure accurate shifting. First, shift your bike into the smallest chainring and loosen the derailleur cable so that the derailleur is in its lowest position. Then, using the limit screws on the derailleur, adjust the height of the cage so that the chain sits directly over the small chainring.
Next, shift into the largest chainring and make sure that the chain shifts smoothly between the two chainrings. If the shifting is slow or the chain hesitates before switching chainrings, you may need to fine-tune the cable tension using the barrel adjuster on the derailleur. If the derailleur fails to shift into the larger chainring or rubs against the chain, you may need to adjust the limit screws. Properly adjusting the front derailleur will ensure smooth shifting and prevent the chain from slipping.
Test Ride and Fine-Tune Your Changes
After completing the process of changing the chainring, the next step is to test your bike on a ride. Start by taking a short ride around your neighborhood or a nearby park. While on the ride, shift between different gears and monitor the bike’s performance. Check if the change has made any significant improvements in the bike’s speed, acceleration, and overall efficiency.
If you notice that the bike is not performing optimally, you may need to fine-tune your changes. Adjust the derailleur settings or the chain tension to ensure that the chain runs smoothly on the new chainring. Keep testing and making adjustments until you are satisfied with the overall performance of the bike. By doing so, you can ensure that your mountain bike is ready to ride on any challenging terrain.
