Schwalbe marathon plus flat less 20 commuter tyre blackhi viz 135 inch
The schwalbe marathon plus flat less 20 commuter tyre 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 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
