MICHELIN A4 Protek Max Schrader Inner Tube - Ultimate Puncture Protection for 29 MTBExperience unparalleled peace of mind on every trail with the MICHELIN A4 Protek Max Inner Tube, the ultimate solution for mountain bikers who demand reliability and performance.

Say goodbye to trailside repairs and hello to more time riding. This is not just an inner tube, it´s an upgrade in confidence and dependability for your 29-inch mountain bike. 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. Optimized for MTB CyclingEngineered for the modern mountain biker, this A4 model is perfectly sized for 29-inch wheels (622 ETRTO), catering to the most popular standard in cross-country, trail, and all-mountain bikes. It is compatible with a wide range of common tyre widths, from 1.85 to 2.40 inches, offering excellent versatility. The tube comes equipped with a durable and reliable Schrader valve, which is widely compatible with most floor and mini pumps, making inflation simple and convenient wherever you are. Whether you´re fitting it to your front or rear wheel, the MICHELIN Protek Max provides a consistent and secure performance upgrade.Technical Specifications:* Product Type: Inner Tubes* Discipline: MTB Cycling* Valve Type: Schrader* ETRTO Width: 47/61* ETRTO Diameter: 622* Web Width (mm): 47/61* Web Diameter (Inch): 29* Web Width (Inch): 1.85 - 2.40* Fitting: Front/Rear* Weight (g): 380. tradeinn Bikeinn

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.Image for illustration purposes only
