A shock absorber ( 1 ), in particular for bicycles, has a first cylinder ( 2 a) with a fluid chamber ( 3 a) filled with a transmission or damping medium. An outwardly leading piston rod ( 6 ) with piston ( 5 a) for receiving the shocks to be dampened is borne axially displaceable in the first cylinder ( 2 a). A second cylinder ( 2 b) that has a fluid chamber ( 3 b) filled with the transmission or damping medium and an air- or gas-filled gas pressure chamber ( 4 b). The fluid chambers ( 3 a, 3 b) of the first and second cylinders ( 2 a, 2 b) communicate with one another via a communicating channel ( 7 ). At least a third cylinder ( 3 c) [sic] with an air- or gas-filled gas pressure chamber ( 4 c) and a fluid chamber ( 3 c) filled with the transmission or damping medium is provided. The fluid chamber(s) ( 3 c, 3 d) of the third and of the additional cylinders ( 2 c, 2 d), if any, is/are mechanically linked to the fluid chambers ( 3 a, 3 b) of the first and second cylinders ( 2 a, 2 b) via a communicating channel ( 7 ), and in the region of the communicating channel ( 7 ) at least one switch apparatus ( 11 ) is provided for blocking or releasing communication between the fluid chamber ( 3 a) of the first cylinder ( 2 a) and one or a plurality of fluid chambers ( 3 b, 3 c, 3 d) of the additional cylinders ( 2 b, 2 c, 2 d)
