Continental 28"/29" 42 mm Presta 47/62-622 MTB inner tube is a bicycle tube designed for 28- and 29-inch wheels with wider 47–62 mm tyres, providing reliable air retention for MTB, trekking and gravel-style bikes.
Key Features
Construction and Design
The tube is made from elastic butyl rubber, which holds air well and adapts to the inner shape of the tyre. This construction is suitable for regular riding on different surfaces, from city streets to gravel roads and forest trails.
The 47–62 mm tyre width range is intended for larger-volume tyres used on MTB, trekking and some gravel bikes. The 42 mm Presta valve fits rims with a narrower valve hole and standard-profile rims.
Main Functions
The tube helps maintain the required air pressure in the tyre and supports stable rolling in different conditions. When installed correctly, it reduces the risk of air loss and allows the tyre to perform consistently on uneven terrain.
The Presta valve allows precise pressure adjustment and is commonly used on performance, MTB and gravel rims. The 42 mm length is suitable for most standard-profile rims.
Use and Compatibility
The tube is designed for 28"/29" wheels with 622 mm rim diameter and 47–62 mm wide tyres. It fits tyres with ETRTO markings within the 47/62-622 range, so the tyre sidewall size should be checked before installation.
This model can be used on 29" MTB, trekking, hybrid and some gravel bikes with wider tyres. During fitting, the rim must be compatible with a Presta valve, and the tube should not be twisted or pinched between the tyre and rim.
Additional Features
The butyl tube requires little maintenance and is suitable both for everyday use and as a spare tube on longer routes. Its compact packaging makes it easy to carry in a backpack, saddle bag or repair kit.
When inflated to the pressure recommended by the tyre manufacturer, the tube helps maintain good grip, stability and tyre performance off-road. Regular pressure checks help reduce the risk of punctures and rim damage.
Summary
Continental 28"/29" 42 mm Presta 47/62-622 MTB inner tube is made for cyclists using 622 mm wheels with wider 47–62 mm tyres. It is best suited for 29" MTB, trekking, hybrid and gravel-style bikes where reliable air retention, a Presta valve and compatibility with larger-volume tyres are important.
