  • Publication number: 20190315428
    Abstract: Example control devices for operating bicycle components are described herein. An example control device includes a housing having an opening to receive a handlebar of the bicycle and a rotating member rotatably coupled to the housing. The rotating member is rotatable about a first axis. The rotating member is configured to rotate between a first position and a second position to change an operating state of a component. The example control device includes a securing mechanism configured to lock the rotating member in the second position. The example control device also includes a release actuator coupled to the housing. The release actuator has an actuating surface to be engaged by a user and moved along a second axis that intersects the first axis. The release actuator is configured to, when actuated, unlock the securing mechanism to enable the rotating member to rotate back to the first position.

  • Patent number: 10435111
    Abstract: A bicycle rear derailleur has a base member mountable to a bicycle frame, a movable member movably coupled to the base member, a chain guide assembly rotatably connected to the movable member for rotation about a rotational axis, a biasing element configured and arranged to bias the chain guide assembly for rotation in a first rotational direction with respect to the movable member, and a fluid damper having a fluid cavity containing a volume of fluid. The fluid damper is operatively disposed between the chain guide assembly and the movable member to apply a damping force to the chain guide assembly when the chain guide assembly rotates in a second rotational direction opposite to the first rotational direction. The fluid damper has a compensation device in fluid communication with the fluid cavity and is configured to accommodate a change in the volume of fluid in the fluid cavity.

  • Publication number: 20190300113
    Abstract: A bicycle control system may be configured to automatically control a bicycle, or components thereof. The bicycle control system may include a system control device configured to provide a simplified shifting system wherein large changes in speed associated with starting and stopping do not require the full attention of the automatic shifting system. The shifting system, or a system control device configured for controlling the shifting system, may be configured to determine when to enter an automatic shifting control mode, establish parameters for the automatic shifting of the automatic shifting control mode, and/or compare detected activities and values of the bicycle to the established parameters.

  • Publication number: 20190283827
    Abstract: A seat post assembly for a bicycle has a first tube with a first distal end and a second tube with a second distal end. The first and second tubes are movable relative to one another to establish a distance between the first and second distal ends. A first pressure chamber has a loaded pressure proportional to a load applied along the tube axis. A second pressure chamber has a second pressure not proportional to the load. A flow path connects the first and second pressure chambers. A valve is disposed along the flow path and is configured to move between a closed position closing the flow path and an open position opening the flow path between the first and second pressure chambers. An isolator of the valve is configured to nullify any resultant force produced by the loaded pressure of the first pressure chamber acting on the isolator.
