Mountain Bike Inner Tubes

MTB inner tubes are the part of the tyre that contains the air and is responsible for the pressure of the tyre. If you get a serious puncture, you might need to replace it so it can be a good idea to keep a spare on hand!

Decathlon has mountain bike inner tubes to suit all sizes of MTB tyres including kids sizes (12"+) through to the most popular 26" and 27.5". It’s not just wheel diameter that’s important, you’ll also want to get the appropriate wheel width. For example, 27.5 x 2.8 means the wheel diameter is 27.5" and 2.8 inches wide.

ETRTO sizing is the European standard which measures in mm rather than inches. For example, the size specification of 37-622 indicates the tyre is 37mm wide and inner wheel diameter is 622 mm.
