A dependable replacement or spare tube for your 29-inch mountain bike.
The Continental MTB Inner Tube is a practical choice for riders who need a replacement tube or want to carry a spare. Its seamless, mould-cured construction is designed for consistent roundness and reliability around the valve stem.
This version has a 42 mm Presta valve. Check that your rim has a Presta valve hole and that the valve is long enough for your rim depth before ordering.
Check Your Tyre Size
Match the tube’s stated tyre-width range to the size printed on your tyre. Check the selected option carefully to make sure it suits your 29-inch tyre.
