27.5" x 1.90/2.50" self-healing inner tube with 48mm presta valve

This inner tube allows you to continue cycling while a traditional inner tube is punctured or flat.

To remove your inner tube, the tools you will need are:

Remove the inner tube easily with a tire lever from B'Twin.

Checks to be carried out before installing the inner tube:

Check the tires for wear and replace them if necessary. A worn tire can cause a puncture: check this before each ride. Replace the tire if it is deformed, cracked, or smooth. Check the tread and sidewalls. Visually inspect the tire (holes and cracks). Change the tire at the first signs of wear. The lifespan of a tire varies depending on usage.

How to change the inner tube:

Before you start, watch our explanatory video. Inflate the inner tube gently, insert the valve into the valve hole, then place the inner tube correctly in the tire, then in the rim without pressing it.

Tire installation:

Place the tire first on the valve side, then place the tire first on the other side. Avoid using a tire lever: this greatly increases the risk of punctures.

Tire inflation:

Inflate the tire slowly, following the pressure indicated on the sidewall (in PSI or bar). Check its correct position throughout the inflation process.

Expert advice:

Check the tire pressure before each ride to avoid tire punctures and ensure optimal performance.

Choosing the inner tube:

To properly maintain your bicycle, it is essential to know the exact dimensions of the tires indicated on their sidewalls (diameter and width). For example, 27.5x2.00 means that the tire diameter is 27.5 inches and its width is 2.00 inches. (50-584) indicates a width of 50 mm and an inner diameter of 584 mm, which is equivalent to 27.5x2.00.
