In our daily work as we deal with bicycle safety, technology and user manuals we come across lots of safety risks. The most frequent ones are published in articles of the leading German special-interest magazines TOUR – Europas Rennrad-Magazin Nr. 1, BIKE – Das Mountainbike Magazin Europas Nr. 1 and E-Bike – Das Pedelec-Magazin to make this information important for the sector accessible to a wider public.
We also speak regularly in independent lectures about all topics relating to bicycle technology and bicycle market. In addition, we are regularly cited by further special-interest magazines or trade journals as well as more and more by radio and television and in their media reports, which shows us that we are completely right with our information. The section NEWS informs you about the latest news from our specialist fields. The reports and publications of this section are listed chronologically or according to topics of interest.
TOUR Do heavy cyclists face safety problems, when they use road bikes?
ZEDLER Overload damage is rare. At present, broken carbon forks are an issue for disc brakes which were not tested properly for the requirements of disc brakes. Big forks are concerned in particular - which is an indication for heavy cyclists.
TOUR Which parts are problematic in practice when the cyclist weighs more than 90 kg?
ZEDLER In most of the cases we happen to see broken parts only with the placement of an accident report order. Complaints addressed towards the manufacturers are not known to anyone else. I would recommend every heavy cyclist asking for test reports. Bicycle manufacturers do not use these reports for advertising purposes - in contrast to the automotive industry.
TOUR What means a higher load to the material: A heavy cycling professional weighing 80 kg or an occasional cyclist weighing 120 kg?
ZEDLER A heavy cyclist brings much more movement into the framework, which is indicated by crackles and cracks, i.e. noises that can only be remedied in parts and at high expenses. Bicycles bearing a 70-kg-cyclist without problem over 10,000 kilometres may brake away under a 110-kg-man within a few kilometres.
