Kamera 28" Continental MV SV42 32/47

Continental 28" MV SV42 32/47 is a bicycle inner tube with a Presta 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 on different riding surfaces.

The SV42 marking refers to a Sclaverand, or Presta, valve with a length of approximately 42 mm. This valve is narrower than an automotive valve, making it suitable for rims with smaller valve holes and commonly used on sport, trekking and hybrid bicycles.

Main functions
The inner tube maintains air pressure inside the tyre and ensures proper wheel performance during everyday riding. It helps preserve tyre shape, cushioning and grip, making it suitable for asphalt, cycle paths, gravel and mixed surfaces.

Continental tubes are made with attention to even wall thickness so the tube holds pressure steadily and expands evenly inside the tyre. This is important for bicycles used frequently in different road conditions.

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 Presta 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 Presta valve allows precise air pressure adjustment and is convenient for rims with a narrower valve opening. The 42 mm valve length is suitable for many standard and slightly deeper-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 with Presta-compatible rims.

Summary
Continental 28" MV SV42 32/47 is made for 28-inch city, trekking and hybrid bicycle tyres with a Presta valve. Its main advantages are compatibility with 32–47 mm tyres, the narrow SV42 valve and suitability for various 28" bicycles. The tube is best suited for everyday and touring riders who need a reliable spare or replacement inner tube.
