All about bicycles, electric-assisted bikes, technology and safety in the press

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.

For many years now the Eurobike Show Daily accompanying the annual international Eurobike Show has given us the opportunity to publish our perspective on major developments in the cycle industry in full-page articles.

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.

Beware of the rim - Rims are wearing parts

The discussion was chaired by Mario Nantscheff, co-owner of an advertising agency and freelance counselor for the bike sector


How did you take notice of this problem?

DIRK ZEDLER, bike-expert and TOUR-editor:

Some reader's letters drew our attention the hard Shimano-Dura-Ace-brake pads eating into the rim and subsequently conducted tests ourselves which confirmed the eating into the rims at high speed and when braking hard. By doing so, partly outrageously expensive rims were destroyed. (...)


How did retailers deal with it? (...)


Since 1996 we have been pointing out in several publications that rims, ie, brake pads should only to be considered coherently and that they are subject to wear and tear. And we called on the manufacturers to cooperate. This attempt to sentizise them apparently deflagrated unheard. Otherwise, we would not be sitting here. (...)


How does Magura inform its customers about which pad matches which rim? (...)


According to our research work, the stress arising in the high-end-sector in practice, which is way higher than stipulated in the DIN-standard, cannot be simulated on any testing device existing in Germany at the moment. In order to do so, you first of all would have to construct test stands able to simulate speeds of more than 70 km/h and the subsequent slowing down before riding through a downhill bend.
