When it comes to a flat tire, sometimes your only recourse is to inflate a new inner tube and then insert it into the bicycle tire. Doing so would be the most reliable method as compared to simply patching the hole on a bike tube. When it comes to shopping for an inner tube, tubes made from brands Continental, Novara and Slime are worth taking a look at.
One thing that you have to remember when looking for bike tubes is the difference between Shrader and Presta tubes. The valves from Shrader tubes resemble valves from car tires while valves from Presta are the slender varieties. A good tip for getting the right sized bike tube is to take a look at the sidewall of your type of bike, for instance mountain bikes. Simply present the information to the sales attendant at the bike shop and you’ll never have to worry about getting the wrong size again or you may also ask some members of bike clubs like the MIT Cycling Club or other clubs nearby.
Talking about size, there are discrepancies when it comes to the width of tires. It's not as easy as choosing bike cables or bike chains. However, you do not have to stress if you have a wide tube and a narrow tire to fit it into. Everything will work just fine. But, it’s completely a different case if you have a narrow tube and a wide tire to fit it into. Inner tubes that are treated so that they resist punctures and flats may seem very convenient but they can also be quite heavy. If you don’t mind the extra weight on your bike, then you can certainly go for those kinds of inner tubes.
