MTT509 Michelin Chambre à air de vélo-Noir - 26 x 37-54 cm
Michelin Protek Max is the ultimate in safety. These tubes offer exceptional puncture resistance, excellent pressure maintenance and are easy to fit. The ultimate in safety, these tubes offer exceptional puncture resistance, excellent pressure maintenance and are easy to fit. Thanks to it`s uneven design, the Protek Max inner tube has a compression reaction in the event of piercing or nipping (the hole closes up naturally), whereas a classic inner tube has an extension reaction (balloon effect). The square shape is naturally positioned in the rim well and does not twist, unlike a completely tubular classic tube. Protek Max only needs to be inflated half as frequently as the standard Michelin Airstop.
