Marathon Plus TourFlat-less - with a purposeful trekking tread. Asphalt or off-road? Everyday use or bicycle expeditions? This versatile tyre always does the job. Its robust construction handles almost any mistreatment. Protected by SmartGuard, the most effective puncture protection belt available for bicycle tyres.It is impossible to guarantee that a flat will never happen, but the Marathon Plus has the best defense against everyday tyre wreckers such as glass, flints or metal shards. Use a pressure gauge to adjust tyre pressures as the common 'thumb check' is insufficient due to the special construction of the Marathon Plus.
