Abstract: A steering system for bicycle handlebars comprises a holding element fixed to the steer tube, in particular above an upper bearing element. A fixing element is arranged between two bearing elements. The fixing element is not directly connected to the steer tube, but is connected, in particular by form-fit, to the holding element by means of a connection means.

Abstract: A quick-release axle system includes two bicycle elements, particular two chain stays. They are connected to each other by means of a quick-release axle. Two clamping elements are provided for the connection, so that a non-positive connection is realized between the two bicycle elements and the quick-release axle.

Abstract: A steering stop for bicycle handlebars includes a first stop element. The stop element can be connected to a steer tube of a bicycle fork in particular in a clamping manner and includes two stops. A second stop element can be fixed on the bicycle frame and cooperates with the first stop element. For passing lines therethrough, which originate for example at a brake and/or gearshift unit, the first stop element includes at least one recess.

Abstract: A guide element for bicycle drive means includes a main bearing pin for fixing a swing arm bearing. Further, a spacer sleeve is provided which is arranged on the main bearing pin for reducing a distance between a drive ring and a bicycle frame element.

Abstract: A bicycle hub quick-release axle has a shaft. A thread for fixing the shaft in a threaded bore in a dropout is provided at the first end of the shaft. A lever element for screwing the thread into/out of the threaded bore is provided at the second end of the shaft. A receiving space for the lever element is provided within the shaft. The lever element can be pulled out of the receiving space. The lever element when pulled out of the receiving spaced is connected to the shaft via holding elements. By this arrangement, simple screwing-in/unscrewing of the shaft is possible with the aid of the lever element.
