How does the tubeless system work?

The BarTubeless system is a special technology that allows tubeless tires to be used without an inner tube, but with an additional safety factor. It is particularly widespread in off-road areas and for motorcycles. Here's a simple explanation of how it works:

1. No inner tube necessary – The BarTubeless system replaces the conventional inner tube with a special rim and tire that seal directly with each other. This means that the tire stays inflated on the rim without air loss and no additional sealant is necessary (although a sealant liquid can be used as an additional safety measure).

2. Sealing bead on the rim – The rim itself has a sealing bead that ensures the tire seals perfectly at the rim edge. This prevents air from escaping, even when the tire is inflated to a lower pressure. This technology provides better grip and more comfort, especially on uneven terrain.

3. Tire inflation and sealing – When inflating the tire, the BarTubeless rim ensures that the tire sits firmly on the rim and no air can escape. So, no inner tube is needed, but the tire remains just as stable as a conventional one with an inner tube.

4. Advantages –

   • Reduced puncture risk: Since there is no inner tube, the risk of a tire immediately deflating from a puncture is significantly lower. This is particularly advantageous in rough terrain.
   • Better performance: You can set the tire pressure much lower, which leads to better grip and more comfort without the risk of a pinch flat.
   • Weight saving: Eliminating the inner tube reduces the weight of the tire system, which is particularly beneficial in competitions or when optimizing riding performance.

In summary: The BarTubeless system combines the advantages of tubeless tires with an additional safety bead on the rim, allowing you to ride without an inner tube while still having a reliable and durable seal. It is an excellent solution for riders who are off-road or in demanding conditions.
