Punctures become obsolete with the Marathon Plus. The SmartGuard® layer made from a flexible, special rubber offers a particular resistance to shards of glass and flints. The SmartGuard® belt does not increase rolling resistance. The Marathon Plus rolls as easily as a tire without protection. SmartGuard® is the most effective protection belt for bicycle tires. Flat-less. A substantial, 5mm thick layer of flexible, special india rubber offers durable protection. SmartGuard® has a crucial advantage especially with objects that lodge in the tread and that can be forced through almost any other protection belt by the rotation of the wheel. The SmartGuard® has the advantage of thickness, because a thumbtack, for instance, simply remains in the rubber without damaging the tube. Blackwall.
