We have different covers mounted on each bike. Zigor with the Schwalve Marathon Plus Tour and Maria with the new flexible Schwalve Marathon Mondiale. The attributes that are influencing the wear are Maria weighs 60 kilos and Zigor 80 kilos and that Maria bicycle, with all the panniers under normal conditions, weighs 55 kilos and Zigor 65 kilos. Maria covers have 13,000 km and Zigor 14. 000km. In terms of pricks the two have had about 3-4 punctures on the rear wheel. The front wheels are quite better than the rear but also note the difference between a model and another. We’ll see the evolution of the covers in the following months, but it gives us that wear of the Tour Plus is quite greater than the Mondiale.
