Unrivaled Puncture ProtectionAt the core of the Protek Max´s incredible performance is its advanced self-sealing capability. The combination of liquid sealant and butyl technology ensures excellent pressure hold. Puncture protection is achieved thanks to an internal liquid sealant and a specific design. This pre-installed sealant instantly and automatically seals small punctures (up to 3mm) in the tread area as they occur, often without the rider even noticing. This proactive defense system means that thorns, glass, and trail debris are no longer a ride-ending threat, allowing you to push your limits on challenging terrain with confidence. Superior Air Retention and DurabilityThe MICHELIN A4 Protek Max inner tube is designed to maintain optimal tyre pressure for longer periods. The advanced butyl technology minimizes natural air loss, meaning you´ll spend less time with the pump and more time on the bike. Furthermore, the tube features an innovative, slightly squared-off profile. This unique shape helps it sit more securely inside the tyre, reducing twisting and providing enhanced resistance to pinch flats—the notorious punctures that occur when the tube gets caught between the rim and an obstacle. This robust construction ensures long-lasting durability, ride after ride.
