Michelin Protek Max Inner Tube

The tube comes pre-filled with a specialized liquid sealant. When a puncture occurs, the air pressure inside the tube forces this liquid into the hole, where it quickly solidifies to create a durable plug, allowing you to keep riding without stopping.

No, this is not the right choice for weight-conscious racing. At 578 grams, it is significantly heavier than standard tubes due to the robust butyl construction and the pre-filled sealant, making it better suited for durability-focused mountain biking.

This tube is designed for 29-inch wheels with a tire width between 2.45 and 3.00 inches. Please check your tire sidewall to ensure your current tire width falls within this specific range before purchasing.

This tube features a 48mm Presta valve. If your rims have a deep-section profile that requires a longer valve stem, this tube will not be compatible, and you may need a valve extender or a different tube.

While the sealant is highly effective, it is a chemical compound that can eventually lose its efficacy over a long period. For optimal performance, we recommend checking your tire pressure regularly and replacing the tube if you notice it no longer holds air effectively after a few seasons of heavy use.
