UPDATED FOR 2014!!
The new Flat-less tire. After 10 years, we have thoroughly overhauled the Marathon Plus. The only true flat-less tire gets a new, dynamic profile and boasts many internal improvements:
Rolling resistance. The patented, 5 mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. We further extended its lead in the latest version.
Recycling. Also in the SmartGuard, we now use a proportion of recycled rubber from old latex products.
"Anti-aging" side wall. It now lasts much longer before developing unsightly cracks when subjected to use with too low air pressure.

A new Marathon with revolutionary puncture resistance!A new Marathon with revolutionary puncture resistance.
The technicians in the Bohle laboratory had to redevelop test procedures in order to puncture the tube inside the Marathon Plus. None of the usual tire destroyers like glass, flints or shards would penetrate the tread and only by extreme application of force could the technicians break through the protection, which in everyday life would be extremely improbable. To back up this trial numerous test riders are still waiting for the first flat on their daily travels.
This new advance in puncture protection is due to the five millimeter thick Smart Guard puncture protection belt made from special india rubber that in conjunction with the tread and carcass brings the total to almost a centimeter of material between the tube and road. "So strong nothing penetrates", assures Bohle technician Markus Hachmeyer. For example a thumbtack will remain lodged in the rubber and cannot penetrate. Smart Guard also protects against the biggest puncture problems experienced by everyday cyclists. Objects that embed in the tread and that insidiously work their way through even the most sophisticated puncture protection belt, promoted by the constant rotation of the tire on the road".
Against 'time bombs' such as shards, flints and glass, only a thick rubber belt like Smart Guard will work.
