BBB Bike Inner Tube 27.5" AV 40 mm

BBB Bike Inner Tube 27.5" AV 40 mm (BTI-68)

The BBB BikeТube 27.5" with a Schrader valve is an exceptionally durable inner tube designed specifically for mountain bikes (MTB) with 27.5-inch wheels, a size that has become one of the dominant standards in mountain biking. This high-quality inner tube is the ideal solution for cyclists looking for reliability and versatility in a variety of terrain 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.

A distinguishing feature of this model is the use of a Schrader valve, also known as a car valve or American valve. This common valve type, with a diameter of 8 mm, is available in lengths of 33 mm for standard rims and 40 mm for rims with a slightly higher profile, and 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 is a major convenience during off-road trips and bicycle tours.

Unlike a Presta valve, the Schrader valve has a built-in spring that keeps the valve in the closed position, eliminating the need to tighten it manually 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 more difficult (e.g. when wearing gloves or in low temperatures). The solid construction of the valve also makes it more resistant to mechanical damage, which is important during intensive off-road riding, where the risk of valve damage is greater.

The 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 a variety of riding styles and terrain types. The narrower variant, weighing from 178 g to 246 g, is ideal for tyres used in trail, all-mountain and enduro riding, where the balance between grip and weight is important. The wider variant, weighing approximately 341 g, is perfect for plus-size tyres that provide maximum traction and cushioning on technical routes. Regardless of the selected size, the BBB inner tube ensures even pressure distribution inside the tyre, resulting in stable bike handling and a reduced risk of unexpected punctures.
