Product description
Michelin Protek Max Bike Inner Tube 27.5" black (black)
This product’s description has been automatically translated. Please excuse any mistakes.
The new MICHELIN tube repairs tyre damage caused by punctures on its own. Specially shaped rubber bulges on the tread and sidewall, when inflated, form a rubber reserve and reduce the surface tension of the tube. If a nail or pointed object pierces the hose when driving over, the "excess" rubber from the curvature closes the hole. At the same time, a special gel inside the hose flows over the injured area and seals it permanently. The MICHELIN Protek Max is available in the standard sizes for city, trekking and mountain bikes and can be combined with all commercially available bicycle tyres (tube type).
