Carbon fiber composite materials (CFRP’s) not only make cars and airplanes lightweight but also benefit the light weight constructions for valuable bicycle concepts. At the Composites Europe trade show in Stuttgart (October 27-29), Fraunhofer researchers will present a spring-loaded seat post made of CFRP’s (Hall 4, Booth D04).
The roadside features such as curbstone edges, potholes, streetcar tracks etc. frequently rattle the nerves of any bicyclist. But for years now, professional and recreational bikers alike have been using spring-loaded seat posts. They absorb the worst shocks, and make the ride more comfortable for the back. Still, for noticeably greater ride comfort, you have to dig deeper in your pockets.
