Medienberichte und Publikationen rund um Fahrräder, Pedelecs, Technik und Sicherheit

Die häufigsten Sicherheitsrisiken, die uns in der täglichen Arbeit rund um Fahrrad-Sicherheit, -Technik und -Bedienungsanleitungen auffallen, publizieren wir auch in Artikeln in den führenden Fachmagazinen TOUR – Europas Rennrad-Magazin Nr. 1, BIKE – Das Mountainbike Magazin Europas Nr. 1 und E-Bike – Das Pedelec-Magazin, um diese für die Branche wichtigen Informationen einer größeren Öffentlichkeit zugänglich zu machen.

Auch die Eurobike Show Daily, Messezeitschrift der jährlich stattfindenden Eurobike Show, gibt uns seit vielen Jahren die Möglichkeit, unsere Sicht auf wichtige Entwicklungen in der Fahrradbranche in ganzseitigen Artikeln auszuführen.

Darüber hinaus sprechen wir regelmäßig in unabhängigen Fachvorträgen über alle Bereiche der Fahrradtechnik und des Fahrradmarktes. Auch weitere Fach- bzw. Branchenzeitschriften sowie immer häufiger Radio und Fernsehen zitieren uns in ihren Medienberichten und zeigen uns, dass wir mit unseren Hinweisen genau richtig liegen. In der Rubrik AKTUELL erfahren Sie laufend alle Neuigkeiten aus unseren Fachbereichen. Diese Berichte und Publikationen sortieren wir für Sie chronologisch bzw. nach Interessensgebieten.

Cracking points

In two tough races in spring the fork steerer tube on the bike of EF pro Tom Van Asbroeck and shortly afterwards the handlebars of superstar Mathieu van der Poel broke. Coincidence? Or is carbon still a risky material after almost 30 years of development? The TOUR report reveals

The crack happened under the eyes of the public: During the spring race Le Samyn the handlebar drop of Mathieu van der Poel’s Canyon Aeroad broke. Miraculously, the cross world champion did not go down. But the missing handlebar piece and the loosely dangling shift brake lever reminded us that carbon involves certain risks. Even companies with a lot of technical expertise like Canyon are not invulnerable to damage to their products. The handlebar breakage presumably due to the interaction of the shift brake lever fixing to the carbon handlebar, is however an unusual incident. Forks break much more frequently.

This year for example during the Omloop Het Nieuwsblad race. The Factor Ostro VAM’s fork of EF pro Tom Van Asbroeck failed above the head tube - luckily without severe fall. Bike manufacturer Factor analysed the damage and identified a defective steerer tube expander and improper mounting as cause. In 2019, the Swiss pro Simon Pellaud went down during the Tour du Doubs when the fork of his Bianchi Specialissima broke during the sprint. Pellaud fell, but was lucky and did not injure himself seriously. He wrote on Twitter that he would never forget the moment when he suddenly held the handlebars in his hands during pedalling, but that he made it across the finish line before he went down and was able to avoid the barriers. He also published the photo of his broken racer but deleted it soon. Copies of it are still available on the internet today.

Is this a random accumulation of problems with carbon components? Rather not. The number one problem area on road racing bikes is not the handlebar, but the steerer tube, says graduate engineer Dirk Zedler, who as a tester and expert witness has an overview of what happens when bikes break (see interview). Google also finds far more hits on broken forks than on broken handlebars. Zedler says: “Although the products have become safer all in all in recent years, it’s in particular the stem clamping on carbon fork steerer tubes that still involves risks.”
