To change an inner tube you will need:
2 tyre levers
15mm spanner (if not quick release)
New inner tube
Tip: Use the left
/ right arrow keys
1. Undo your brake's quick release, and remove the wheel from the bike either with the quick release skewer or 15mm spanner. Let the air out of the tyre by unscrewing the Presta valve and pushing down on the tyre to release the air, or if you have a Shrader valve, press down on the pin inside with a tyre lever. Once the air is out unscrew the valve ring.
2. Grab your tyre lever, and starting opposite end of the valve, line it up with one of the spokes. Hook the scooped shape end underneath the bead of the tyre. Then take the second tyre lever, sneaking it underneath the tyre bead and start to peel the tyre of the rim.
3. Now go to the valve, pull the tyre up away from the rim and carefully push out the valve from the rim and remove the inner tube.
4. Make sure you have the right sized inner tube for your tyre (the numbers are on the sidewall of your tyre), and pump a little bit of air from the track pump into the tube so it takes a 3-D shape.
5. Carefully place the valve inside the tyre and through the valve hole in the rim, and start tucking the tube in, making sure it doesn’t get twisted.
6. Holding the wheel on your lap across from you, starting at the valve, tuck the tyre bead back into the rim using your thumbs. Make sure you work the crossover points where the tyre and rim intersect, and take care that the inner tube doesn’t get caught in between the tyre and the rim. If it gets tough, deflate the innertube fully to give yourself some more room. You can also try pulling more tyre down from the opposite end of where the tyre won't go in. But whatever you do, DO NOT USE TYRE LEVERS here. You can cause a pinch flat and will have to start over again.
