Best Mountain Bike Tubes

Good tubes for your mountain bike are only partially about the size of your rim and tire. While that is an important consideration before purchase, you will also want to think about buying a tube with extra durability for the rough trails you plan to ride. Some include an inner sealant product, which can automatically seal small punctures, keeping your tire inflated longer. Valve stems may be slightly shorter or longer in different models. There are also 2 types of valve stems: Presta and Schrader. Make sure the stem you purchase is compatible with your rim. Before you buy any tube, make sure it is both the right diameter and the right width for your tire.
