Michelin Protek Max Tube

The Protek Max tube features a specialized rubber structure that creates a compression reaction when punctured. This design naturally pinches the hole closed, which helps seal small punctures and prevents air from escaping as quickly as it would with a standard tube.

This tube is designed for 27.5-inch wheels with a tire width between 2.40 and 3.00 inches. Please check your tire sidewall to confirm your specific wheel diameter and width before purchasing.

Yes, the 48mm Presta valve core is removable. This is particularly useful if you need to add sealant or use a valve extender.

At 405 grams, this tube is heavier because it is built with thicker, more durable rubber designed specifically for puncture resistance and impact protection. It is a trade-off: you gain significant reliability and fewer flat tires on the trail at the cost of a little extra rotational weight.

Yes, the specialized construction and rubber compound help the tube retain air pressure longer than traditional butyl tubes. While you should still check your tire pressure before every ride, you will likely find yourself topping off the air less often.
