The Schwalbe Marathon Plus has been redesigned after 10 years. The one and only “flat-less“ tyre gets a dynamic tread and shows it's the best by its strong properties. The patented 5 mm thick SmartGuard layer has a clear advantage compared to all the imitation products, a clear example of this is the rolling resistance. In the latest version they extend this advantage even further. The Dev “Anti-Aging“ sidewall endures the typical overload due to an insufficient tyre pressure, it endures this much longer before cracks start to appear.
