There are other types of types other than the standard tube that can add an element of prevention to your ride. They will save you time out on the trail or on your way to work by either completely preventing a puncture or sealing the puncture immediately. This added advantage comes at a higher price point but is worth the investment for many types of riders – commuters, mountain bikers, tour riding or anyone that would rather be enjoying their ride than fixing a puncture. You should, in theory, not have to replace these types of tubes as often as you would standard inner tubes.
Self sealing inner tubes have a sealant inside them. When you puncture the sealant will fill your puncture hole and harden fixing your problem immediately. This system works on punctures up to 3mm wide so it is still recommended that you carry a spare tube incase of slashing type flats. You may also have to rotate your wheel to get the sealant to fill the hole then pump any air you have lost back in.
Thorn resistant inner tubes are 3x as thick as a standard inner tube. This makes them really durable and strong so they are less likely to puncture. This type of inner tube is popular with mountain bikers who often find themselves surrounded by gorse. These tubes are not designed to be carried as a spare tube in a bike tool kit, they are considerably bigger & heavier than standard inner tubes.
You can also get inner tubes that have been designed to match a certain type of riding. Downhill inner tubes are durable & strong, designed to handle hard impacts better than a standard inner tube. Lightweight inner tubes are all about reducing weight allowing a competitive rider to perform better.
