    Abstract: A bicycle rear derailleur includes a base member mountable to a bicycle frame. A movable member is movably coupled to the base member. A chain guide assembly is rotatably connected to the movable member for rotation about a rotation axis. A biasing element is configured to bias the chain guide assembly for rotation in a first rotational direction with respect to the movable member. A damper assembly 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 damper assembly includes a one-way roller clutch assembly disposed coaxially about the rotational axis and a friction unit extending circumferentially over a circumferential angle coaxially about the rotational axis.

    Abstract: The invention provides a wireless control system for a bicycle, including at least one shift actuator generating an input signal when actuated and a master control unit transmitting a shift signal responsive to the input signal. At least one electromechanical gear changer is provided and includes a gear changer control unit. The gear changer control unit receives the shift signal from the master control unit and controls the at least one electromechanical gear changer corresponding to the received shift signal. The gear changer control unit listens for the shift signal during a part of an awake mode cycle time, the master control unit transmitting the shift signal for a message duration time which is greater than the awake mode cycle time.

    Abstract: A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to a controller of the bicycle. The controller is configured to instruct an assist motor to activate based on the measured wheel speed and/or the measured crank cadence.

    Abstract: Brake rotors for bicycles are described herein. An example brake rotor for a bicycle includes a carrier to be coupled to a hub of the bicycle. The brake rotor also includes a brake track having braking surfaces to be engaged by brake pads. The brake track is disposed radially outward of the carrier. The brake track has a first thickness and the carrier has a second thickness greater than the first thickness. The brake track is coupled to the carrier such that the brake track is axially movable relative to the carrier while being radially and circumferentially constrained relative to the carrier.
