How to Repair a Bicycle Inner Tube using a Patch Kit

Описание: This video will demonstrate the proper way to patch a bicycle inner tube using self-vulcanizing patches. Patching an inner tube is often the most cost-effective way to fix a punctured tube. However, if the hole is bigger than the patch kit the tube will need to be replaced.

First, start by removing the tier and tube. This process starts by opening the quick release lever then loosening the opposite screw. With a through-axle start by opening the quick release lever then loosening the axle on the same side. Through axles may use a hex key which will most commonly require a 5 or 6mm Allen key. With the back wheel shift to the smallest gear. Then bend the derailer back and navigate the wheel around the chain. Sram derailleurs have a lock to keep the derailleur fully extended. Remember do disengage the lock once the wheel is back on the bike.

To uninstall the tube, remove all the air. Flat ha-ha. Push the tyre to the centre of the then use a tire lever to remove the tier from the rim. And finally, remove the tube from the tier.

Next, identify where the leak is coming from. Pump up the tube and listen for air escaping. If you can’t find the leak, try submerging the tube underwater. Now mark where the hole is.

To install the patch first sand the area around the hole. This will help the patch stick to the tube. Now apply some of the rubber cement. I’m cutting this open as there’s little left in the funnel. It’s best practice to leave the cement for roughly 5 minutes before applying the patch. Then apply the patch. I didn’t show it here however peel off that plastic layer.

That’s it! Well, you’ve got to reinstall the wheel and if you really wanted to put your patched tube back in the water so see if it’s still leaking but other than that you're done! So that’s it for this week’s video. If you enjoyed it, please make sure to do what every other YouTuber tells you to do. Thanks guys.
