BBB innertube SL 29" FV 48 mm bicycle inner tube

BBB innertube SL 29" FV (BTI-89S) bicycle inner tubeThe BBB BikeТube 29" with Presta valve is a professional inner tube designed for mountain bikes (MTB) equipped with 29-inch wheels, which have become the dominant standard in modern mountain biking. This high-quality inner tube combines durability, reliability and the right level of flexibility, making it an ideal choice for racers, enthusiasts and recreational cyclists looking for the best solutions for their bicycles. Made from premium-quality butyl rubber, it provides an excellent balance between puncture resistance and flexibility, which is particularly important for large 29-inch wheels.A key feature of this inner tube is the advanced Presta valve, also known as the French valve, which is a standard in professional mountain biking. This valve is available in two lengths (40 mm for standard rims and 48 mm for higher-profile rims) and features a slim design and a smaller diameter than the traditional Schrader valve. This not only reduces the weight of the entire inner tube, but also minimises the size of the valve hole in the rim, increasing its structural integrity – particularly important for 29-inch wheels, which are exposed to greater loads when overcoming obstacles on off-road terrain.One of the main advantages of the Presta valve is its ability to maintain higher tyre pressure and provide precise pressure control. Thanks to the small locking nut at the end of the valve, the amount of air in the inner tube can be adjusted very precisely, allowing the tyre parameters to be optimally matched to the route conditions and riding style. This is particularly important for 29-inch wheels, where the correct pressure has a crucial influence on the bike’s handling, traction and rolling resistance. The Presta valve is compatible with all standard bicycle pumps equipped with the appropriate head, as well as with floor pumps and CO2 compressors, which are invaluable for quick repairs on the trail.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 a variety of riding styles and terrain types. It is ideal for tyres used in cross-country and marathon riding, where low weight and low rolling resistance are important. Regardless of the selected size, the BBB inner tube ensures even pressure distribution inside the tyre, resulting in predictable bike handling and a reduced risk of defects, which is particularly important during long rides and MTB races.Key features:SL – “SuperLite” – a lighter version of the standard inner tube for lower weight and improved performanceHigh-quality butyl rubber providing optimal airtightness and durabilityPresta valve (French valve) available in 40 mm and 48 mm lengths, suitable for different rim profilesLighter valve construction compared to a Schrader valvePrecise pressure control thanks to the special locking nutAvailable widths: 1.90–2.30" (47–57 mm) and 2.10–2.35" (54–60 mm)Compatible with modern 29" MTB tyresReinforced joint ensuring excellent airtightness even at high pressureSpecifications: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: Presta (French valve)Valve length: 40 mm / 48 mmETRTO: 47/57-622, 54/60-622
