HOW TO remove & change an inner tube the right way: Tips from a Professional Bike Mechanic #2

Introduction

This tutorial will guide you through the process of removing and changing a bicycle inner tube, utilizing professional techniques. Understanding how to properly handle punctures can save you time and prevent frustration during your rides. Whether you find yourself in a rainy lay-by or at home, these steps will ensure you can effectively manage a flat tire.

Chapter 1: Removing the Tyre

1. Create Space

   • Pinch the tire and push it down into the well of the rim to create slack. This makes it easier to remove the tire.

2. Use Tire Levers

   • Grab your tire levers (ideally three, but two will suffice). Start from the side opposite the valve.
   • Insert one tire lever underneath the tire bead and hook it outward to lift the tire.
   • Avoid forcing the tire as this can damage the tube, bead, or rim.

3. Remove One Side of the Tire

   • Use a second tire lever to assist in lifting the tire off the rim.
   • Carefully run your fingers around the inside of the rim to ensure only one side of the tire is removed.

Chapter 2: Removing the Inner Tube

1. Extract the Tube

   • Start by pulling the tire back at the valve. Grip the valve firmly and drag it out while working your way around the tire to remove the tube.
   • If the tube has been in the tire for a while, it may stick to the tire due to previous repairs. Pull firmly to extract it.

2. Assess the Tube

   • Determine whether the tube can be repaired. To do this, inflate it and listen for hissing sounds to locate the puncture.
   • If you find a puncture, consider patching it later. If the tube is beyond repair, dispose of it responsibly.

Chapter 3: Finding the Cause of the Puncture

1. Inspect the Tire

   • Check the outside of the tire for any foreign objects (e.g., glass, thorns) that may have caused the puncture.
   • Look for signs of wear and tear, such as cracks or fraying.

2. Examine the Inside of the Tire

   • Look inside the tire for any remaining debris or sharp objects that could cause future punctures.
   • If no foreign objects are found, consider if the tube itself failed due to a pinch flat or valve issue.

Chapter 4: Fitting a New Inner Tube

1. Prepare the New Tube

   • Take your new or repaired tube and insert the valve through the valve hole in the rim. Ensure the valve is well-placed.

2. Insert the Tube

   • With the wheel on the ground for support, feed the tube into the tire, ensuring it's evenly distributed.

3. Finish at the Valve

   • Start fitting the tire back onto the rim from the valve area, working away from it. This prevents the tube from getting trapped.
   • If you encounter resistance, pinch the tire to create more slack and help ease the tire over the rim.

4. Ensure Proper Seating

   • Once the tire is on, check that it is seated evenly around the rim. Look for any visible lines or bulges that indicate improper seating.

Chapter 5: Valve Caps and Nuts

1. Understand Valve Components
   • Valve caps and lock rings can help secure the valve, but they might cause damage if over-tightened. Use them cautiously.
   • Consider the environmental impact of valve caps, as they can contribute to waste if lost.

Conclusion

By following these steps, you can efficiently remove and replace a bicycle inner tube, ensuring that you are prepared for any puncture situation. Regularly inspecting your tires and tubes can help prevent future issues. Keep a spare tube and basic tools handy during your rides for quick repairs. Happy cycling!
