Michelin tube C4 Protek Max 26" 47/58-559

Punctures caused by perforation or pinch shock (kerbs in the city or rocks when mountain biking...) are what every cyclist dreads. Repairing or changing an inner tube is not always an easy matter. An inner tube has to be re-inflated regularly.

The ultimate in puncture resistance
Because of its unique bumpy design, the MICHELIN Protek Max inner tube creates a compressive force if it is holed or pinched (the hole seals itself naturally) whereas a conventional inner tube stretches (balloon effect). The self-sealing effect is accentuated with the addition of sealant in the manufacture of the tube.

Ease of fitting
Thanks to its square shape, the MICHELIN Protek Max inner tube positions itself naturally in the rim well and does not twist, unlike a completely tubular conventional tube.
