Arregla un pinchazo: poner un parche | Repara tu bici

Introduction

In this tutorial, you will learn how to repair a flat tire on your bicycle using a puncture repair kit. This skill is essential for all cyclists, as flat tires are a common issue. Being prepared with a repair kit and knowing how to use it can save you time and trouble on your rides.

Step 1: Gather Your Tools

Before you start the repair process, ensure you have all the necessary tools at hand. You will need:

• A puncture repair kit (includes patches, glue, and sandpaper)
• A tire lever (to remove the tire from the rim)
• A pump (to inflate the tire after repair)
• A clean cloth (to wipe off debris)
• A marker or chalk (to mark the puncture location)

Step 2: Remove the Wheel

To access the flat tire, follow these steps:

1. Shift Gears: If your bike has gears, shift them to the smallest cog to make wheel removal easier.
2. Loosen the Quick Release: If your bike has a quick release mechanism, open it to detach the wheel. If not, use a wrench to loosen the nuts.
3. Take Off the Wheel: Carefully lift the wheel out of the bike frame.

Step 3: Remove the Tire

Now you need to take the tire off the rim:

1. Insert Tire Lever: Place the tire lever between the tire and the rim at one point.
2. Lift the Tire: Use the lever to pry the tire away from the rim, sliding it around the rim to detach one side completely.
3. Remove the Inner Tube: Once one side of the tire is off, pull the inner tube out carefully.

Step 4: Identify the Puncture

To find the hole in the inner tube:

1. Inflate the Tube: Pump air into the tube slightly.
2. Listen for Air Leaks: Rotate the tube and feel for escaping air.
3. Mark the Puncture: Once identified, mark the puncture with a marker or chalk.

Step 5: Prepare the Patch

Now it's time to apply the patch:

1. Clean the Area: Use a clean cloth to wipe the punctured area.
2. Roughen the Surface: Use sandpaper (included in the kit) to roughen the area around the puncture. This helps the patch adhere better.
3. Apply Glue: Spread a thin layer of glue over the puncture and let it sit for a minute to become tacky.

Step 6: Apply the Patch

Follow these steps to attach the patch:

1. Position the Patch: Place the patch over the puncture, ensuring it covers the area completely.
2. Press Firmly: Press down on the patch for a few seconds to ensure a strong seal.
3. Let it Cure: Allow the patch to set for the time recommended on the glue instructions.

Step 7: Reassemble the Tire

Now that the patch is secure, reassemble the tire:

1. Insert the Inner Tube: Carefully push the patched inner tube back into the tire.
2. Reattach the Tire: Starting from one side, push the tire back onto the rim, ensuring it fits snugly.
3. Check Alignment: Make sure the tire is evenly seated on both sides of the rim.

Step 8: Reinstall the Wheel

Finally, put the wheel back on the bike:

1. Place the Wheel in Frame: Align the wheel with the bike frame and secure it using the quick release or nuts.
2. Tighten Securely: Make sure everything is tightened properly to avoid any issues while riding.

Step 9: Inflate the Tire

Complete the process by inflating the tire:

1. Attach the Pump: Connect your pump to the valve of the inner tube.
2. Inflate to Recommended Pressure: Check the side of the tire for the recommended PSI and inflate accordingly.
