Fixing a puncture on a mountain bike is a task every cyclist should be able to do. It's easy to do when you know how, but many people make the job harder by not following the correct steps. Properly seating the tyre in the rim will reduce the need for tyre levers, and adding a small amount of air to the tube will make it easier to fit. Always carry a spare tube or patch kit and hand pump when you are out on your bike. It's also best to invest in a track pump to keep at home so that you can easily get the tyre up to the proper pressure.
This is a long guide, so you can choose to either watch the entire video above, or follow it in smaller chunks by clicking on the individual steps below.
Steps to Fix A Puncture On A Mountain Bike:
Even if you only ever plan to fit new inner tubes it's useful to know how to patch a inner tube. You may have multiple punctures on one trip and a patch kit - which only weighs a few grammes - will help get home. It's also useful if you meet a rider without puncture tools whose inner tubes are a different size to the ones you carry. If you want to patch inner tubes for routine re-use the most efficient way is to store punctured inner tubes until you have a few and then process them together.
The recommended pressure to inflate a tyre to is usually embossed on the tyre's sidewall, often as minimum and maximum figures rather than an exact target. There are a number of factors to consider when deciding how hard your tyres need to be(link to tyrepressurecheck.html)
