  • Patent number: 8960385
    Abstract: A pull shock damper for a bicycle comprising a spring device and a damper device, the spring device comprising a positive spring and a gas-operated negative chamber. The damper device comprises a first oil chamber and a second oil chamber connected therewith. The negative chamber abuts the first oil chamber via a piston. A tubular structure extends from the piston through the negative chamber interior up to the end of the negative chamber. The piston rod of the piston extends through the first oil chamber to the exterior.

  • Patent number: 8196947
    Abstract: A suspension fork for a bicycle includes at least one stanchion tube and at least one slider tube interacting therewith and a wheel receiving space adjacent thereto. The suspension fork includes a damper system with a damper chamber divided into a first chamber and a second chamber by a movable piston. The suspension fork further includes a damping device for the rebound stage and a damping device for the compression stage are provided. A shut-off valve is provided for selectively locking the rebound stage. The damper chamber comprises a connecting duct with a flow damper that connects the second chamber with the first chamber when the stanchion tube and the slider tube interacting therewith are compressed more than a predefined distance such that in the case of a forceful compression and with the shut-off valve of the rebound stage activated, slow decompression is allowed up to a damper position as defined by the predetermined distance.
