Kamera 29" Continental Ventil: Sclaverand/französisch/Scl. 47/62 - 622 MTB

Continental 29" Sclaverand 47/62-622 MTB is a bicycle inner tube designed for 29-inch MTB tyres with a Presta valve. It is used on mountain, trekking and sport bikes with 622 mm wheels where an inner tube for wider 47–62 mm tyres is required.

Main features

Construction and design
The tube is made from elastic rubber, allowing it to adapt to several tyre widths within the specified range. The 47–62 mm compatibility makes it suitable for many 29" MTB tyres used on forest trails, gravel roads and mixed surfaces.

The Sclaverand valve, also known as Presta or French valve, is narrower than an automotive valve and is commonly used on sport and mountain bikes. This valve type fits rims with a narrower valve hole and allows more precise air pressure adjustment.

Main functions
The tube maintains air pressure inside the tyre and ensures proper wheel function on different surfaces. It helps keep the tyre shape, grip and cushioning, especially when riding with wider MTB tyres.

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 on rough terrain, where the wheel is exposed to frequent impacts and load.

Use and compatibility
The tube is intended for 29" wheels with a 622 mm ETRTO diameter and tyres with a width from 47 to 62 mm. It fits sizes within this range, such as 29 x 1.75, 29 x 2.0, 29 x 2.25 and similar MTB tyre sizes.

Before installation, it is important to check that the rim is designed for a Presta valve and that the tyre size matches 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 is useful when using sport rims with a narrower valve hole. It also makes it easy to release air and adjust tyre pressure more accurately before riding.

Thanks to its wide compatibility, this tube is suitable as a spare part for longer rides, training or regular bicycle maintenance. It can be used off-road, on gravel or on asphalt with wider 29" tyres.

Summary
Continental 29" Sclaverand 47/62-622 MTB is made for 29-inch bicycles with wider MTB-style tyres and rims designed for Presta valves. Its main advantages are compatibility with 47–62 mm tyres, the narrow French valve and suitability for various mountain and trekking bikes. The tube is best suited for riders who need a reliable spare or replacement inner tube for a 29" wheel.
