All about bicycles, pedelecs, 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.

Two broken saddles

Why cyclists loose their seats in Rio

Augsburg. There is nothing unusual about defects on bicycles. Every now and then, tyres are concerned by punctures or gear systems don’t function as they should. However, a saddle breaking away is rather seldom. All the more when the bicycle is not a rusty model from the 50ies. Or is it not?

Rio 2016, two broken saddles, track bike, Zedler

During the Games in Rio this curiosity happened to occur even twice within a few weeks, during the Olympic and the Paralympic Games. And this under professional conditions during the world’s major sports events. Concerned by this incident were track cyclist Kristina Vogel loosing her saddle during the final spurt and Hans-Peter Durst whose saddle had already loosened right after the start.

Bicycle expert Dirk Zedler from Ludwigsburg gives an explanation. Vogel’s track bicycle is an extremely lightweight carbon model. If fine cracks in the carbon occur as a result of too much pressure, for example due to overtightened bolts at the seatpost, the material becomes instable.

On Hans-Peter Durst’s model the saddle is mounted like on a common bicycle. It was designed and assembled by frame builder Sven Krautscheid: “The saddle is fastened with two bolts. One of these bolts broke”, he explains. According to Krautscheid, due to a material defect.

A problem that often occurs, says Dirk Zedler, not only for professional riders, but also for the elder woman riding to the green market once a week. “The saddle bolts must be tightened properly. This is best done by using a torque wrench”, recommends the expert. This is something that is neglected by many cyclists. But once a bolt starts wobbling, it wouldn’t take long until it breaks. “In the case of Hans-Peter Durst the breakage can also be due to the assembly. That is to say when a bicycle is often disassembled and reassembled”, explains Zedler. He is happy that the athletes remained uninjured: “Their reaction was good, because they are professionals. Normal cyclists would have fallen with serious consequences.”
