BBB Bicycle Inner Tube BikeTube 27.5" FV (BTI-68)

BBB BikeТube 27.5" with a Presta valve is a professional inner tube designed for mountain bikes (MTB) equipped with 27.5-inch wheels, which have become one of the most popular standards in mountain biking. This high-quality inner tube combines durability, reliability and a lightweight construction, making it an ideal choice for both amateurs and experienced cyclists looking for a dependable solution on the trail. Made from premium-quality butyl rubber, it provides an excellent balance between puncture resistance and flexibility.

A key element of this inner tube is the advanced Presta valve, also known as a French valve, which is extremely popular among mountain biking enthusiasts. Available in two lengths (33 mm for standard rims and 48 mm for higher-profile rims), this valve 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 during intensive off-road riding.

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 accurately, allowing the tyre parameters to be optimally matched to the route characteristics and riding style. The Presta valve is compatible with all standard bicycle pumps equipped with a suitable pump head, as well as with floor pumps and CO2 compressors, which are invaluable for quick repairs on the trail.

BBB BikeТube 27.5" is available in two width variants: 2.00-2.40" (51-61 mm) for standard MTB tyres and 2.80-3.00" (71-76 mm) for wider plus-size tyres, allowing it to be matched to various riding styles and types of terrain. The narrower variant, weighing from 178 g to 227 g, is ideal for tyres used in cross-country, trail and all-mountain riding, where a balance between grip and rolling resistance is important. The wider variant, weighing approximately 341 g, is perfect for plus-size tyres that provide maximum traction and comfort on demanding trails. Regardless of the selected size, the BBB inner tube ensures even pressure distribution inside the tyre, resulting in predictable bicycle handling and a reduced risk of punctures.
