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.

11-speed assembly

Reader’s question

I have a Mavic Cosmic Elite wheelset originating from the year 2001 or 2002. I would like to assemble an 11-speed cassette from SRAM. Is this possible from the technical point of view and what do I have to keep in mind?

Reply by Dirk Zedler, TOUR technology expert and bicycle expert

The assembly of an 11-speed cassette on a wheel of that generation is normally no longer feasible. The cassette body is different in width and shows modified screwings on the lockring. For this reason it will most probably be impossible to provide a firm fit of the SRAM cassette. In this area the road bike technology is considered more and more exhausted, as a consequence of which it is increasingly difficult to combine different components. I think you will be forced to also buy a new wheel, whether you like it or not, to be able to ride an 11-speed gear. The question whether it is possible to replace a driver body by an 11-speed driver body, cannot be answered ad hoc. Most probably, however, such a replacement is no longer reasonable under the economic aspect, because this wheel type is offered at quite favourable prices on the internet whereas spare parts are clearly more expensive.
