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.

Lightweight bike - Illegally lightweight

Interview on the development of lightweight bikes

TOUR: There are lots of tuning suppliers offering their products on the market of extremely safety-relevant components, such as seat posts, handlebars, stems. Are those lightweight components safe?

Zedler: From my experience, the components of experienced German suppliers, such as Tune, Schmolke, AX Lightness, THM, are the most state-of-the-art components available on the current market. The manufacturing of these components is not suited for the series manufacturing in the Far East and therefore nothing speaks against them being lightweight. In this field the technology has reached Formula One level including all consequences.

TOUR: And what would those be?

Zedler: DIYs should keep their hands off these components. Such high-end components are only as good as the mechanic assembling them. As a minimum you need a good torque wrench, carbon assembly paste and the necessary amount of experience to tighten the bolts by starting from a minimum value and approaching the indicated tightening torques in small steps. Overtightening, even though by only half a turn, the combination of incompatible components, and yet a safe component turns into an accident risk.

TOUR: Where is a tuning reasonably priced, safe and promising?

Zedler: Virtually all bikes up to premium mid range bikes allow a weight saving of 400 to 800 grams in the area of the wheels without loss of function. A lot of weight saving can be achieved by using other tires and tubes and really acceptable system wheels with alu rims do not weigh more than 1,400 grams – these are however rarely included in the original equipment. As regards the gear and brake components, there is in my opinion only little potential for tuning beyond the top systems.
