Inner tube a3 28" 700x32/42 protek max st 35mm 32/42-622 Michelin

Inner tube Michelin 28 • a3 protek max valve st auto 35mm. Punctures from punctures or pinch flats (edge of sidewalks in the city or on stones on a mountain bike) represent the greatest fear for all cyclists. Repairing or changing an inner tube is never a very simple operation, as is periodically inflating it. Thanks to its irregular design, the MICHELIN Protek Max inner tube reacts in "compression" in the event of a puncture or pinch (the hole closes naturally) while a classic inner tube reacts in "extension". The self • closing effect increases thanks to the sealing liquid originally present in the inner tube. Thanks to its square shape, the MICHELIN Protek Max inner tube sits naturally on the bottom of the rim and does not turn, contrary to what happens with a classic fully tubular inner tube.
