As a mountain biker, regular maintenance of your bike is an essential part of ensuring your ride is both safe and enjoyable. One of the most common issues faced by most mountain bikers is a flat tire. While changing a front tire might be a piece of cake, changing a rear tire can be quite a daunting task. However, with the right guidance, the process of changing a rear tire on your mountain bike can become an easy feat.
This step-by-step guide will take you through all the necessary steps required to change the rear tube of your mountain bike. Whether you are a seasoned mountain biker or a beginner, this article will give you the confidence to tackle a flat tire on your own, anytime and anywhere. So grab your tools and let’s get started with this easy process of changing your rear tube on your mountain bike.
Preparing for the Rear Tube Change: Essential Tools and Materials
Preparing for a rear tube change is crucial if you want to efficiently and effectively replace the tube. You should have the following tools and materials ready;
First up, ensure you have a spare tube that matches the size and valve type of your bike. Secondly, you should have tire levers, a bike pump, or CO2 inflator. The tire lever helps you remove the tire from the wheel, while the bike pump or CO2 inflator will come in handy when filling the new tube with air. Additionally, you should have a wrench for removing the wheel from the bike; make sure it’s the right size for your bike.
Other essential items include a patch kit, lubricant, and cleaning wipes. The patch kit can be used if you experience another flat tire on the way, and lubricant ensures that your tire moves smoothly on the wheel. Finally, cleaning wipes help remove any dirt, or debris from the bike wheel as you replace the tube. Having all these tools and materials ready will make the rear tube change process much more manageable, and you’ll be back on the trail in no time.

Removing the Rear Wheel: Step-by-Step Instructions
The second step towards changing the rear tube on your mountain bike is to remove the rear wheel from the bike frame. This process can seem intimidating, but it is relatively simple if you follow the step-by-step instructions below.
First, shift the bike into the smallest cog on the cassette to relieve tension on the chain. Then, flip the bike over and locate the quick-release lever on the rear wheel. Unscrew the nut on the opposite side to loosen the axle and remove the wheel from the frame. Be sure to keep track of any washers or spacers that come off the axle during the process. With the rear wheel removed, you can proceed to the next step of changing the rear tube on your mountain bike.
Disconnecting the Rear Brake: A Detailed Guide
Disconnecting the rear brake is a crucial step when changing the rear tube of your mountain bike. It is important to ensure that the brake is disconnected properly, so that you can work on the wheel without any hindrance. The process of disconnecting the rear brake may differ slightly depending on the type of brake system you have installed on your bike. However, the steps provided here are a general guide that most mountain bikes use.
First, find the brake cable that attaches to the brake lever on the handlebars. Follow the cable down to where it attaches to the rear brake caliper. Locate the bolt that attaches the cable to the brake caliper and use an Allen wrench to loosen and remove it. This should release the brake cable from the caliper and allow you to untangle the cable from the brake lever. Your rear brake is now disconnected, and you can proceed to remove the rear wheel and change the tube. When you’re done, simply reattach the brake cable by following the same steps but in reverse order.

Removing the Old Rear Tube: Tips and Tricks
Removing the old rear tube from your mountain bike can be a tricky process, but with the right tools and technique, you can get it done quickly and easily. The first step is to release the brake, and then shift the bike to its highest gear to make it easier to remove the wheel from the frame. If you have quick-release skewers, simply open the lever and unscrew the nut to release the wheel. If your bike has bolts instead, use a wrench to loosen them and remove the wheel.
Once the wheel is removed, deflate the tire completely and use tire levers to remove one side of the tire from the rim. Pull the old tube out and be sure to check the inside of the tire for any debris or sharp objects that may have punctured the tube. Keep in mind that the process of removing the old tube may vary slightly depending on your specific bike model and tire size.
Installing the New Rear Tube: Dos and Don’ts
Installing the new rear tube may seem like a straightforward process, but it’s essential to follow the dos and don’ts to prevent any future punctures. Firstly, ensure that the valve is aligned correctly with the rim. You can do this by placing the valve through the hole, screwing the nut, and giving it a slight wiggle. Doing this will prevent any air escaping and possible damage to the valve stem.
When installing the new tube, avoid pinching the rubber. The tube movement should translate into fewer pinch flats, so it’s important to avoid over-stretching or twisting the tube during installation. Ensure it’s evenly distributed around the wheel to prevent any imbalances that may cause punctures. Finally, add air to the tube, and adjust the tire pressure according to the recommended range to avoid over or under-inflation, limiting future flats and ensuring you’re set up for a smooth ride.
Reattaching the Rear Wheel and Brake: A Comprehensive Guide
After successfully replacing the rear tube of your mountain bike, it’s time to reattach the rear wheel and brake system. This step is vital as improperly fitting the wheel and brake can lead to dangerous accidents.
First, place the wheel back into the rear dropouts, ensuring that it sits flat against the frame. Next, tighten the quick release lever, ensuring that the wheel is securely in place. Afterward, reattach the brake caliper, making sure that the mounting bolts are tightened securely. Finally, check that your brake pads are aligned with the rim and that they are not rubbing against the tire. Once you have completed these steps, spin the wheel to check for any wobbling or rubbing, and make any necessary adjustments. With these steps, you’re now ready to hit the trails!

Testing your Rear Tube: How to Spot and Fix Common Issues
After changing the rear tube on your mountain bike, it is important to test it for any issues. The most common issue is a slow leak, which can be fixed by simply adding more air to the tire. However, if the tire continues to deflate, there may be a puncture or hole in the tube that needs to be patched or replaced.
To spot a puncture or hole, visually inspect the tube for any obvious tears or rips. If you can’t find anything, inflate the tire to its maximum pressure and listen for a hissing sound or feel for any air escaping. If you find a puncture, remove the tube and patch it with a bicycle-specific patch kit or replace the tube entirely. Make sure to check the tire itself for any sharp debris that may have caused the puncture. By testing and fixing any issues with your rear tube, you can ensure a smooth and safe ride on your mountain bike.
The Conclusion
Changing a rear tube on a mountain bike seems like a daunting task for beginners, but with the right tools and knowledge, it is a straightforward process that can be done in minutes. The most important step is to identify the type of valve used in the tube, whether Presta or Schrader, and have the correct pump and spare tube at hand.
In summary, changing a rear tube on a mountain bike involves removing the wheel, deflating the tube, detaching the tire, replacing the tube, reattaching the tire, and inflating the tube with the right pressure. Practicing this skill should be an essential part of a biker’s knowledge, as it can save them from being stranded in the middle of a trail with a flat tire. Remember, maintenance is key to ensuring a long lifespan for your bike, and changing tubes is one way of taking care of it.
