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.

Do brakes destroy rims?

No rim lasts forever: Brake shoes keep grinding the rim until it cracks. Reason to panic? No – but a reason to be alert. TOUR tells you when there is a danger.

Horror news scared mountain bikers at the end of the year: front wheel tubes suddenly bursting, brakes failing on fast downhills, knife-sharp rim parts endangering the rider's life and lots of dramatic crashes. If you believed the press reports, breaking rims were an imminent danger to every biker - and mountain bikes were especially dangerous. Also the alleged reasons seem easily made out. Shimano’s high-performance V-brakes and Magura’s Hydro brakes were revealed exemplarily as rim destroyers in the first instance. Finally, rim brakes in general were called into question as faulty designs. These sensational reports united with the borders between facts and speculations becoming less clear. Our investigations show, what the subject of rim failure really is all about.

First of all: It is not new that braking can harm and even destroy the rim. Bikers who ride a lot have known this phenomenon since aluminium rims were introduced for bike wheels in order to safe weight. In comparison with conventional steel rims, the surface of aluminium rims is softer - and increasingly exposed to the aggressive power of the new brakes. Nevertheless, breaking rim sides cannot simply be blamed on V-brakes or other models. The rim's wear depends on the way you brake.
