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.

Pedal mounting

Reader’s question

I bought a Wilier Cento 1 with SRAM-Red components. To make the test ride I had brought old pedals to my dealer which I wanted to change afterwards at home. Foolishly, I was a little confused when tightening the right hand pedal with the Allen key. I started tightening the pedal, instead of loosening it. When I noticed my error, I could loosen it without problems. What I fear now is that the carbon crank was damaged due to the wrong direction of tightening. Nevertheless, I did not apply force when tightening in the wrong direction by using a standard Allen key and applying pressure from the top. I could neither hear any cracking or the like. The threaded sleeve did not show any signs of damage, hair cracks were not visible from the outside. The pedal fits perfect and tight, there is no play perceivable during the ride. How can I check, whether everything is all right?

Confusing the rotational direction when screwing in or out the pedals is something that happens quite often. In most of the cases this remains without consequences, as long as you haven’t applied excessive force. But this is actually the point that we cannot judge from a distance. One important thing is the length of the tool, as the leverage multiplies your force, thus increasing the torque value. In most of the cases the manufacturers indicate 40 Newton metres as maximum torque value for pedals. This is quite a high value – with a usual L- or T-Allen key such a torque value cannot be achieved. Even with a longer version of the L-key it is hard to achieve 40 Newton metres. Therefore, consider yourself and find out whether you’ve worked with an overly long lever and/or by applying too much force. The major signs which would indicate a damage were mentioned by yourself and could not be found by you. For a detailed analysis the crankset would have to be tested thoroughly.
