Continental's new range of inner tubes makes it easy to find the one that's right for you. The user-friendly offer corresponds to multiple sizes, valve types, lengths and designs, as well as different tire types and riding styles. The variety of inner tubes allows you to make the right choice: the standard inner tube is available in all sizes, offering the best compromise between daily riding and weight, while the Light and Supersonic versions are most concerned with weight and rolling resistance.

The inner tube fits wheels with tire sizes in the range of 27.5" x 1.75" - 2,5" (47/62-584).
In the above range is given the diameter of the wheels to which the inner tube fits, that is, 27.5" (ETRTO 584) and the width of tires with which it is compatible:from 1.75" to 2.5" (ETRTO 47-62).

Presta valves are pumped using exactly the same pumps as dunlop (bicycle) valves.
