The new Marathon Plus is not only flatless, but even faster than before. Its thick protection belt of highly elastic rubber reliably fights off all puncture demons and rolls lighter than any other tyre with a thick protection belt. Now also approved for e-bikes.
When the Marathon Plus was launched in 2002, it revolutionised puncture protection. Not even glass shards and thumbtacks were able to harm it. Therefore, the Marathon Plus is still the only tyre that may be said to be truly "flatless".
