Product Description

The new MICHELIN tube repairs tyre damage caused by punctures all by itself.

Specially shaped rubber curvatures on the tread and flank, when inflated, form a rubber reserve and reduce the surface tension of the tube. If a nail or pointed object pierces the tube while riding over it, the "excess" rubber from the curvature closes the hole. At the same time, a special gel inside the tube flows over the injured area and seals it permanently. The MICHELIN Protek Max is available in the usual sizes for city, touring and mountain bikes and can be combined with all commercially available bicycle tyres (tube type).


  • Ultimate breakdown safety thanks to integrated breakdown milk
  • new shape makes assembly easier
  • exceptional air tightness even when pierced

Huge disappointment
Grosse déception
Translated from French To the original

Purchase on August 6 of these inner tubes. I have just done 10km with for the first time and a puncture on stones. Irreparable 2mm hole. I will test my second room, hoping not to be disappointed.

Achat le 6 août de ces chambres à air. Je viens de faire 10km avec pour la 1ere fois et crevaison sur des cailloux. Trou de 2mm irréparable. Je vais tester ma deuxième chambre en espérant ne pas être déçu.

Good in theory, but bad valve quality
In der Theorie gut, aber Ventil-Qualität schlecht
Translated from German To the original

I installed 3 of these hoses with SV valve and in 2 the valve was not really tight and I had creeping air loss.

Ich habe 3 dieser Schläuche mit SV Ventil verbaut und bei 2 waren das Ventil nicht wirklich dicht und ich hatte schleichenden Luftverlust.

I find the super!
Ich find den super !

My son had a hard time on his MTB. Since I installed this hose in April 2016, I never had to repair. Whether the is now a little heavier and whether the ringer goes; I do not believe that. The tire and the air pressure are much more important. In any case I do not have to repair the hose every day.

Mein Sohn hatte an seinem MTB dauernd platten. Seit ich diesen Schlauch im April 2016 montiert habe, musste ich nie mehr reparieren. Ob der jetzt etwas schwerer ist und ob das ringer geht; ich glaube das merkt niemand. Da ist wohl der Reifen und der Luftdruck viel massgebender. Jedenfalls muss ich damit nicht alle par Tage den Schlauch reparieren.
