A gearshift for a bicycle having an electric auxiliary drive including a stepped gear system which is embodied as a hub gear system or derailleur system, and an electromechanical actuator for triggering a gear change of the gear system. The electromechanical actuator has a shift control unit which can be or is connected via a data line to a drive control unit of the auxiliary electric drive, which shift control unit is designed to activate the actuator as a function of at least one state parameter transmitted to the shift control unit by the drive control unit, or as a function of an item of information derived from said state parameter.

The invention relates to a roller bearing of a wheel hub of a motor vehicle comprising a tire pressure control system. Said roller bearing comprises an air guiding channel that extends radially through an external ring and an air guiding channel that extends radially through an internal ring that leads into an intermediate chamber that is arranged between the rows of the bearing bodies and is sealed in relation to said bearing bodies. In order to seal the intermediate chamber in a more simple and effective manner, said intermediate chamber comprises a flow channel that is embodied as a Venturi nozzle.
