All about bicycles, electric-assisted bikes, technology and safety in the press

The most common safety risks that we come across in our daily work around bicycle safety, technology and operating instructions are also published by us in articles in the leading German special-interest magazines TOUR (Europe's road bike magazine no. 1), BIKE (Europe's mountain bike magazine no. 1), MYBIKE and EMTB in order to make this information, which is important for the industry, available to a wider public.

For many years now, the Eurobike Show Daily, trade fair magazine of the annual Eurobike Show, has also given us the opportunity to publish our view of major developments in the cycle industry in full-page articles.

We also speak regularly in independent expert presentations about all areas of bicycle technology and the bicycle market. In addition, we are quoted by further special-interest magazines of the industry and the trade as well as increasingly by radio and television in their media reports, which shows us that we are spot on with our advice. The section "News" informs you about the latest news from our specialist areas. The reports and publications of this section are listed chronologically or according to areas of interest.

That was pioneering work

Together with Robert Kühnen Dirk Zedler developed and launched the TOUR test 30 years ago: Today, the graduate engineer, expert witness and loss adjustor is a leading international bicycle expert: In this interview, we look back on 30 years of TOUR test history and the road bike present

TOUR: 30 years ago, TOUR started testing road bikes reproducibly on test stands, initially for bottom bracket and head tube stiffness. What was the motivation for this and how did it come about?

DIRK ZEDLER: The first carbon wave started in the mid to late 1980s and at the same time welded aluminium frames from the USA reached Europe. While carbon was initially almost phased out again due to quality problems, aluminium frames from Klein and Cannondale and later from Müsing from Germany and Principia from Denmark were serious challengers to the somewhat dusty Italian steel frame builders. Their reaction to the lightweight metal frames were increasingly thin-walled tubes, which posed a challenge, shall we say, when riding downhill. As young engineers, Robert and I could now either write against the ego of the classics or provide evidence of technical properties. So we sat down and drew our first test sketches on napkins in the organic farm pub in true cliché style.

How was this received by the readers and the road racing bike industry?
