Abstract: A handlebar stem, in particular for racing bicycle handlebars, comprises a main element which is connected to a handlebar at a front end. The main element is connected to the handlebar stem tube in the area of a rear end. The handlebar stem tube is connectible to a steerer tube such that it is bendable in the longitudinal direction to improve riding comfort.

Abstract: A handlebar stem system for bicycle handlebars includes a steerer tube and a handlebar stem tube. The handlebar stem tube protrudes into the steerer tube. By means of a clamping device arranged within the steerer tube, is it possible to clampingly connect handlebar stem tube and steerer tube. According to the disclosure, the clamping device includes a clamping means, such as a screw, which protrudes into the steerer tube through an insertion opening therethrough.

Abstract: A racing bicycle handlebar includes a transverse support connected to a handlebar stem or integrally formed therewith. Two arcuate lower handle elements are connected to the transverse support. The connection is established by a connecting element respectively arranged between the transverse support and the respective handle element. In addition to clamping areas for fastening brake lever units, the connecting elements also includes gripping areas. The gripping areas are arranged between the clamping areas and the transverse support in order to improve ergonomics or prevent pressure marks, wherein in particular an upper side is provided with a smaller curvature or flattening, respectively.

Abstract: A method for quantitatively characterizing at least one temporal-sequence (TS) of an object-attribute-error of an object, for at least one scenario of a plurality of scenarios; the object having been detected by a sensor of a plurality of sensors; including: providing at least one TS of sensor-data of a plurality of TSs of sensor-data of the sensor, for the at least one scenario; determining a TS of at least one object-attribute of the object with the TS of sensor-data; providing a sequence of a reference-object-attribute of the object of the scenario, corresponding to the TS of the object-attributes; determining a sequence of object-attribute-difference by comparing the sequence of the object-attribute to the sequence of the reference-object-attribute of the object; generating an error-model for describing TSs of object-attribute-errors of objects; the object having been detected by the sensor, with the TS of the object-attribute-difference, to quantitatively characterize the object-attribute-error.

Abstract: A bicycle handlebar includes a central part for connection with a handlebar stem or formed integrally with the same. Two outer parts are detachably connected with the central part such that they are variable in their position. The width of the handlebar can be adjusted individually.

Abstract: A bicycle frame element has a seat tube (10). A clamping element (20) is arranged in the seat tube (10), on which element a clamping force is exerted by a clamping means (34) to fix a seat post (30) in the seat tube (10). Further, a bearing element (22) for defining the lateral position of the seat post (30) is arranged in the end portion (16) of the seat tube (10), when in the mounted state.

Abstract: A handlebar stem for bicycle handlebars has a stem element connected to a holding element. The holding element has a tube opening and surrounds a steer tube in the mounted state. A clamping element is arranged in the holding element. Using a clamping device, a clamping force is exerted on the clamping element for fixing the handlebar stem to the steer tube.
