Punctures are a memory. The SmartGuard layer made from a flexible, special rubber offers particular resistance to shards of glass and flints. Even a thumbtack cannot penetrate this protective layer. The SmartGuard belt does not increase rolling resistance. The MARATHON PLUS rolls as easily as a tyre without protection.
