Michelin Protex Max Presta Valve Tube 40mm Size 700x35 47

Thanks to its uneven design, the Michelin Protek Max Presta Valve 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 self plugging effect is increased by adding the sealant at the origin. Easy to Fit : Thanks to its square shape, the Michelin Protek Max inner tube is naturally positioned in the rim well and does not twist, unlike a completely classic inner tube. Excellent Pressure Maintenance : The Michelin Protek Max inner tube needs to be inflated half as frequently as the classic Michelin AIRSTOP. Size 700x35 47
