Marathon Plus 700x28 Smartguard

The new Flat-less tire. The only true flat-less tire with a patented, 5 mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. Also in the SmartGuard, we now use a proportion of recycled rubber from old latex products. It now lasts much longer before developing unsightly cracks when subjected to use with too low air pressure.
