Composite wheel rim

A shock absorber (), in particular for bicycles, has a first cylinder () with a fluid chamber () filled with a transmission or damping medium. An outwardly leading piston rod () with piston () for receiving the shocks to be dampened is borne axially displaceable in the first cylinder (). A second cylinder () that has a fluid chamber () filled with the transmission or damping medium and an air- or gas-filled gas pressure chamber (). The fluid chambers () of the first and second cylinders () communicate with one another via a communicating channel (). At least a third cylinder () [sic] with an air- or gas-filled gas pressure chamber () and a fluid chamber () filled with the transmission or damping medium is provided. The fluid chamber(s) () of the third and of the additional cylinders (), if any, is/are mechanically linked to the fluid chambers () of the first and second cylinders () via a communicating channel (), and in the region of the communicating channel () at least one switch apparatus () is provided for blocking or releasing communication between the fluid chamber () of the first cylinder () and one or a plurality of fluid chambers () of the additional cylinders ()
