A method of preparing an electrostatic dissipative composition that includes combining a conductive polymer; a crosslinkable polymer, and a crosslinking agent to form a fluidized dispersion, and providing the fluidized dispersion with a pH of about 7 to 9 to form the electrostatic discharge composition. The front frame has a head tube, a down tube, a top tube, a bottom bracket shell and a seat tube. The rotary body and the slider decrease a width of a door by an overlapping movement of a female guide groove and a male protrusion. In another embodiment, the strut arms of the basket include undulations. The channel thus estimated is used to make an equalisation before the analysis filter bank. At least one stop is associated with one of the shaft elements, against which the pressure springs abut after having passed through a free displacement path of the cage between the two shaft elements, which free displacement path is not loaded by the pressure springs.
