A bicycle chain is used to transmit the drive force to at least one chain wheel and contains chain rollers and inner and outer plates which are connected to each other by means of pins. As a result of a corresponding shaping of the extremely hard inner plate, the wear on the teeth which cooperate with the inner plate can be reduced on the chain wheels or sprockets.
A multi-sprocket arrangement for installation on a rear wheel axle of a bicycle includes a sprocket assembly. The sprocket assembly has at least a first sprocket and a second, self-supporting sprocket. The second sprocket is connected to a holding body via the first sprocket by way of a separate, cylindrical fastener which extends parallel to the rear wheel axle. The fastener has a first and a second end which are connected in frictionally fit fashion to drilled holes in the first and second sprockets. The frictionally fit connection between the fastener and the drilled holes of the sprockets prevents an axial movement of the first and second sprockets toward one another. The fastener is additionally connected, at the first and second ends, in form-fitting fashion, to the first and second sprockets such that an axial movement of the first and second sprockets away from one another is also reliably prevented.

A front derailleur device for a bicycle chain shift includes a frame fixing part for attachment to a bicycle frame, a hinge arrangement which is pivotable relative to the frame fixing part, and a chain cage which is pivotable relative to the frame fixing part via the pivotable hinge arrangement for guiding and pivoting of the bicycle chain. The hinge arrangement includes at least two hinged struts which can be mounted rotatably relative to the frame fixing part and relative to the chain cage about pivot axes. The pivot axes run substantially parallel to each other and, in a mounted state of the derailleur device on a bicycle, may be oriented substantially vertically.
The present invention relates to a hub for a bicycle, having a hub axle, a hub sleeve which is mounted rotatably on the hub axle via a bearing arrangement, a driver which is mounted rotatably on the hub axle via a bearing arrangement and is coupleable to the at least one hub sleeve in a torque-transmitting manner, wherein the bearing arrangement has at least one axially inner bearing and at least one axially outer bearing. At least one fastening element is provided, which fixes at least the inner bearing of the bearing arrangement in its predetermined position on the hub axle by a local or sectional enlargement of the cross section of the hub axle.
The present invention relates to a freewheel hub for a bicycle, comprising a freewheel device which optionally allows relative rotation between a hub sleeve and a driver or couples the hub sleeve and the driver in a torque-transmitting manner. The freewheel device has at least one first clutch ring and at least one second clutch ring, wherein the first clutch ring is coupled or coupleable to the hub sleeve in a torque-transmitting manner, and wherein the second clutch ring is coupleable or coupled to the driver in a torque-transmitting manner, and wherein the first and the second clutch ring are displaceable axially relative to the hub axle between an engaged position and a freewheel position. Provision is made here for at least one magnet arrangement accommodated in apertures in the first clutch ring to keep the clutch rings in the engaged position.

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 rotational axis. A biasing device is configured to bias the chain guide assembly in a first rotational direction relative to the movable member. A damper assembly is 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 including radially inner and outer clutch members and roller elements acting between the inner and outer clutch members and a friction device including a friction biasing device and friction surfaces axially biased against and in frictional engagement with the one-way roller clutch assembly by the friction biasing device. The friction surfaces are axially offset with reference to the rotational axis relative to the roller elements.
