Inner Tubes

Purebike, your go-to source for mountain bike gear, has selected the best brands to offer you a wide range of inner tubes suited to your riding style, safety needs, and tire size.

How do you choose the right inner tube size?

To find your inner tube size, simply check the markings on the sidewall of your tire. For example, a marking of 29 x 2.00 indicates a wheel diameter of 29 inches and a tire width, or tread width, of 2.00.

Which type of inner tube should you choose: standard, reinforced, or puncture-resistant?

Even if you have excellent tires suited to your recreational rides or your sport riding style, such as Enduro, Cross-Country, or All-Mountain, keep in mind that your wheels are among the components subjected to the most stress as they absorb sometimes violent impacts (potholes, jumps, high-speed turns).
That's why, after choosing the best tire to help prevent punctures, you should fit it with the right inner tube.

Standard inner tube

A standard inner tube is mainly made from butyl sheets. This elastic, durable material can expand to withstand air pressure. Its main advantage is its low price.

Reinforced inner tube

As the name suggests, a reinforced inner tube has a greater wall thickness (between 1.2 and 1.5 mm). It's made from butyl to provide the necessary elasticity, and its reinforcements offer greater longevity. This type of reinforced inner tube offers much better resistance to punctures and pinch flats, while serving as a good alternative to tubeless tires. Some brands, such as Schwalbe, use highly advanced materials to make reinforced inner tubes that are lighter than standard models.

Puncture-resistant inner tube

A puncture-resistant inner tube contains sealant that automatically plugs the hole if a puncture occurs. This solution is effective for punctures smaller than 3 mm. Joe’s No Flats is well known for this type of product. It’s a practical choice that lets you continue your ride or trail outing if you get a flat.
