Decathlon 29 X 1.9 / 2.5 Inner Tube 48mm Schrader Valve

This inner tube is suitable for 29 diameter tyres with 1.90 to 2.50 section with a 48mm Schrader valve."

HOW TO CHOOSE YOUR INNER TUBE

Check all the information indicated on the sidewall of the tyre (diameter and width). For example, 29x1.90 means that the tyre is 29 inches in diameter and 1.90 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-7622 means that the tyre is 50mm wide with a 622mm internal diameter (approx. 29x2.00).

TIP FROM THE PROS

To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.
