BBB bicycle inner tube innertube 29" AV 40 mm

BBB bicycle inner tube innertube 29" AV (BTI-89)The BBB BikeТube 29" with a Schrader valve is an exceptionally durable inner tube designed specifically for mountain bikes (MTB) with 29-inch wheels, which have become the standard in modern mountain biking. This high-quality inner tube is an ideal solution for cyclists seeking reliability and versatility in a variety of off-road conditions. Made from high-quality butyl rubber, it provides an excellent balance of durability, flexibility and puncture resistance, resulting in a long service life even on the most demanding trails and during intensive use.A distinctive feature of this model is the use of a Schrader valve, also known as a car or American valve. This common valve type, with a diameter of 8 mm and a length of 40 mm, is popular due to its versatility and ease of use. Its main advantage is compatibility with almost all types of pumps – from specialist bicycle pumps and floor pumps to standard car pumps and compressors available at petrol stations. This versatility is particularly appreciated during long MTB trips, where the ability to use different inflation sources can prove invaluable in emergency situations.Unlike a Presta valve, a Schrader valve has a built-in spring that keeps the valve in the closed position, eliminating the need to manually tighten it after inflating the tyre. This is particularly useful for cyclists who value simplicity of use or ride in difficult conditions where handling small components can be challenging (e.g. while wearing gloves or at low temperatures). The robust construction of the valve also makes it more resistant to mechanical damage, which is important during intensive off-road riding on 29-inch wheels. These wheels can overcome obstacles more easily, but they also generate greater loads on the components.The BBB BikeТube 29" is available in two width variants: 1.90-2.30" (47-57 mm) and 2.10-2.35" (54-60 mm), allowing it to be matched to different riding styles and types of terrain. Regardless of the selected size, the BBB inner tube ensures even pressure distribution inside the tyre, resulting in stable bicycle handling and a reduced risk of unexpected defects, which is particularly important during longer cycling trips far from civilisation.Key features:Durable butyl rubber providing excellent puncture resistance40 mm Schrader (car) valveUniversal compatibility with most pumps, including car pumps and compressors at petrol stationsAutomatic valve with a built-in spring, eliminating the need for manual tighteningAvailable widths: 1.90-2.30" (47-57 mm) and 2.10-2.35" (54-60 mm)Increased valve resistance to mechanical damageIdeal for intensive off-road riding and a variety of conditionsSpecifications:Wheel size: 29" (622 mm)Available widths: 1.90-2.30" (47-57 mm) / 2.10-2.35" (54-60 mm)Material: Butyl rubberValve type: Schrader (car/American)Valve length: 40 mmWeight: approximately 215 gETRTO: 47/57-622, 54/60-622
