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.

Dura-Ace Di2 in 20,000-km endurance test

It runs and runs

Once through the complete test laboratory, twice the TOUR-Transalp, six different frames and about 20,000 kilometres of running performance – these are the reference values of our Dura-Ace-Di2 endurance test group. Since the beginning of 2009 the pre-series model has enriched completely conspicuously the test fleet of TOUR. Unconspicuously, as the group always sets the benchmark in terms of shifting precision from the first to the current gear shifts, as it never stops, can be easily assembled, disassembled and adjusted. Even the rechargeable battery is still so fresh that you don’t have to fear a cutting of power, not even during an about 900-km-long race, such as the Transalp. Even when the battery stops the supply, which may be the case after 2,000 kilometres without recharging, the front derailleur no longer works, but there are still about 70 kilometres left, where the rear derailleur is working still properly when cycling to the charger. The only flaw to the externally still almost irreproachable group concerns the front derailleur, where chromium has chipped off the external aluminium guide plate on the bottom edge.
