Continental MTB 29 47/62-622 is a 29-inch mountain bike inner tube with a Schrader valve, designed for tyres measuring approximately 1.75–2.50 inches in width.

Key Features

Construction and Design

The tube is made from flexible butyl rubber, providing reliable air retention for regular cycling use. Its seamless construction and mould-cured vulcanisation help maintain a consistent round shape when inflated.

The 47/62-622 ETRTO marking indicates compatibility with tyres using a 622 mm bead-seat diameter and widths between 47 and 62 mm. This corresponds to approximately 29 × 1.75–29 × 2.50-inch MTB tyres.

Main Functions

The butyl rubber construction creates an airtight layer between the rim and tyre. When correctly selected and installed, the tube maintains stable pressure for riding on paved roads, gravel tracks and mountain bike trails.

The Schrader valve is the same general type commonly used on car tyres. It can be inflated using a compatible bicycle pump, compressor or service-station air pump while observing the pressure range marked on the tyre.

Use and Compatibility

The tube is designed for 29-inch mountain bike wheels with a 622 mm rim diameter and tyres measuring 47–62 mm in width. It is suitable for tyre markings such as 47-622, 50-622, 54-622, 55-622, 57-622 and 60-622 when they fall within the stated range.

Before purchase, the rim should be checked for compatibility with the wider Schrader valve. During installation, the tube must not be trapped between the tyre bead and rim, and any sharp debris inside the tyre or rim should be removed.

Additional Features

The standard Continental MTB tube is a practical spare for training, commuting and off-road rides. When folded, it can be carried in a saddle bag or tool case together with tyre levers and a pump.

Summary

The Continental MTB 29 tube is intended for cyclists using 29-inch wheels, 1.75–2.50-inch tyres and a Schrader valve. Its broad tyre compatibility, butyl rubber construction and easily inflated automotive-style valve make it suitable for everyday riding and replacing a punctured tube.
