A specific design combined with an internal liquid guarantees significant pressure and excellent puncture protection. During compression, holes seal up naturally.
Punctures due to perforation or nipping impact (edges of sidewalks in the city or rocks for mountain bikes, etc.) are a major fear among all cyclists. Repairing or changing an inner tube is not always a very simple operation. An inner tube must be regularly re-inflated. Thanks to its uneven design, the Michelin Protek Max inner tube undergoes a "compression" reaction in the event of piercing or nipping (the hole closes up naturally), whereas a classic inner tube has an "extension" reaction (balloon effect). This self-plugging effect is enhanced by adding the preventive sealant originally supplied.
