Inner tube Continental 28" MV AV40 32/47

Continental 28" MV AV40 32/47 is a bicycle inner tube with an automotive-style valve, designed for 28-inch wheels and tyres from 32 to 47 mm wide. It is suitable for city, trekking, hybrid and touring bikes using medium-width 700C / 28" tyres.

Main features

Construction and design
The tube is made from elastic rubber, allowing it to adapt to different tyre widths within the specified 32–47 mm range. This construction helps the tube expand evenly inside the tyre and maintain stable air pressure during everyday riding.

The AV40 marking refers to a Schrader automotive-type valve with a length of approximately 40 mm. This valve is robust, easy to use and compatible with many standard pumps and compressors.

Main functions
The inner tube holds air pressure inside the tyre and ensures proper wheel performance on asphalt, cycle paths, gravel and mixed surfaces. It helps maintain tyre shape, cushioning and grip, making it important for both daily commuting and longer rides.

Continental tubes are made with attention to even wall thickness so the tube holds pressure steadily and reduces the risk of uneven stretching. This is especially useful for bicycles used frequently on different types of terrain.

Use and compatibility
The tube is intended for 28" wheels with tyres from 32 to 47 mm wide. It fits many common sizes used on city, trekking and hybrid bikes, such as 700 x 32C, 700 x 35C, 700 x 38C, 700 x 40C and similar sizes.

Before installation, it is important to check that the rim is designed for a Schrader valve and that the tyre size falls within the tube’s stated range. During installation, the tube should not be pinched between the tyre bead and rim, and the tyre should be checked for even seating before full inflation.

Additional features
The Schrader valve is convenient for everyday use, as it can be inflated with many standard pumps without an additional adapter. The 40 mm valve length is suitable for most regular-profile rims.

Thanks to its wide tyre width range, this tube can be used as a spare part for daily commuting, touring rides or home bicycle maintenance. It is suitable for riders using versatile 28" tyres who need a simple and practical replacement tube.

Summary
Continental 28" MV AV40 32/47 is made for 28-inch city, trekking and hybrid bicycle tyres. Its main advantages are compatibility with 32–47 mm tyres, a convenient Schrader valve and a 40 mm valve length. The tube is best suited for everyday riders who need a reliable spare or replacement inner tube for a 28" wheel.
