Mountain biking is a thrilling and exciting sport that requires a lot of maintenance and upkeep. One of the most common issues faced by mountain bikers is a punctured inner tube in the rear tire. Changing the inner tube may seem like a daunting task for beginners, but with the right guidance, it can be a quick and easy fix.
In this article, we will guide you through the process of changing the rear inner tube of your mountain bike. From identifying the problem to completing the repair, we will outline the step-by-step instructions to help you get back on the trails in no time. Whether you are a seasoned rider or new to the sport, this beginner’s guide will provide you with the necessary knowledge to confidently change a rear inner tube on your mountain bike.
Understanding the anatomy of a mountain bike rear tire
Before you attempt to change the rear inner tube on your mountain bike, it’s essential to understand the anatomy of the tire. The rear tire of a mountain bike is made up of several components – the tire itself, the rim, the inner tube, and the spokes. The tire provides traction and grips the surface, while the rim is the metal ring that holds the tire in place on the wheel.
The inner tube is a crucial component that holds the air that keeps the tire inflated. It is situated between the rim and the tire and should fit snugly into the tire’s cavity. The spokes are the metal rods that connect the rim to the wheel hub and help to distribute the rider’s weight evenly. Understanding how these components work together is essential to ensure that you can replace the inner tube correctly without causing any damage to the wheel.

Gathering the necessary tools and equipment for the job
Before you begin the process of changing the rear inner tube of your mountain bike, it is important to gather all the necessary tools and equipment. You will need a set of tire levers, a bicycle pump, a replacement inner tube, and a wrench. Make sure that the wrench you choose fits the size of your rear axle nuts.
Additionally, it may be helpful to have a workstand or something to prop your bike up on while you work on it. This will make the process easier and more comfortable. Once you have all the necessary tools and equipment gathered, you are ready to move on to the next step of changing the rear inner tube on your mountain bike.
Removing the wheel and old inner tube from your bike
Before you begin to replace the inner tube, the first step is to remove the wheel from your bike. To do this, you will need to use a wrench or quick-release levers to loosen the bolts that secure the wheel onto the bike frame. Once the bolts are loosened, tilt the bike to one side to remove the wheel from the frame. Make sure to take note of any disc brakes, and to carefully maneuver the wheel past them as you remove it.
Now that you’ve removed the wheel, it’s time to take out the old inner tube. Begin by locating the valve stem, and unscrewing the cap that covers it. Next, use your tire levers to pry the tire away from the rim, starting at the opposite end of the valve stem. Once you’ve got the tire partially off, gentle pull the inner tube out from between the tire and rim. Be careful not to damage the tube by pulling too hard on the valve stem or getting it caught on any sharp edges of the rim. Once completely removed, move on to installing the new inner tube.

Inspecting the tire for any damage or wear that may require replacement
Before changing the rear inner tube on your mountain bike, it is important to inspect the tire for any damage or wear that may require replacement. One of the most common signs of tire wear is the presence of visible cracks on the sidewalls or treads. This wear can be caused by a variety of factors, including age, exposure to sunlight, and rough terrain. If you see any cracks, it is recommended that you replace the tire before installing a new inner tube to ensure optimal safety and performance.
In addition to checking for wear, you should also inspect the tire for any punctures or cuts that may have caused the inner tube to become damaged. Small punctures and cuts can often be repaired with a patch kit, but larger damage may require a replacement tire. By taking time to carefully inspect the tire before changing the inner tube, you can ensure that your mountain bike will operate safely and efficiently.
Inserting and inflating the new inner tube
After removing the old inner tube, it’s time to install the new one. First, make sure that the tire is properly seated on the rim. Insert the new inner tube into the tire, starting at the valve and working your way around the perimeter, making sure not to twist it. Be sure to tuck the valve stem up into the tire so that it’s not pinched between the tire and rim.
Once the inner tube is in place, inflate it slightly to give it shape, but not so much that it’s fully inflated. Check again to make sure that no part of the tube is caught between the rim and tire. Then, carefully insert the valve stem through the valve hole in the rim, making sure that it’s straight and secure. Finally, inflate the tire to the recommended pressure, which can be found on the sidewall of the tire. Give the tire a quick spin to make sure that it’s running smoothly, and you’re good to go!
Reinstalling the rear wheel onto your mountain bike
Reinstalling the rear wheel onto your mountain bike is a crucial step in the process of changing the rear inner tube. After successfully removing the old tube and installing the new one, the next step is to put the wheel back in place. Begin by sliding the axle into the dropouts, making sure that it is aligned properly. Once it is in, tightly screw the nuts or quick-release skewer on both sides.
Next, check that the wheel is centered and straight by spinning it to see if it is rubbing against the frame or brake pads. Adjust accordingly. Finally, make sure to check that the gears are shifting correctly and that the brakes are functioning as they should. Take a test ride to ensure that the wheel is securely in place and that everything is working correctly. With these steps, you can easily reinstall the rear wheel onto your mountain bike and be ready to hit the trails again in no time.

Properly disposing of the old inner tube and cleaning up your workspace
It’s important to properly dispose of your old inner tube once you’ve successfully replaced it. Leaving it lying around can not only be unsightly, but can also pose a hazard to the environment. Before disposing of it, ensure that the tube is completely deflated. You can puncture it with a sharp object to prevent it from re-inflating. Next, check with your local recycling center to see if they accept rubber for recycling. If they do not, you can always dispose of it in the trash.
Finally, it’s important to clean up your workspace after you’ve finished. Gather all the tools and equipment you used and store them in a safe place. Sweep or wipe down the area to remove any debris or dirt, making sure to dispose of anything that could cause harm to you or others. By cleaning up after yourself, you not only protect the environment but also ensure that your next repair job is less messy and more efficient.
The Bottom Line
To sum up, changing the rear inner tube on a mountain bike may seem daunting at first, but with the right tools and a bit of practice, it can be easily done at home. Starting with identifying the exact location of the puncture, the necessary tools required for the job, and removing the wheel, the process can be completed in minimal time.
Remember to inspect the tire and rim for any damage or wears and to make sure the new tube is inflated to the correct pressure before reattaching the wheel. With these steps in mind, you can quickly get back on the road and enjoy your mountain biking adventure without worrying about flat tires.
