Abstract: A telescopic seat post, in particular for fastening in a seat tube (SR) of a bicycle (FR), includes: —a tubularly configured telescopic element with a longitudinal axis (LA) and a cavity extending along the longitudinal axis (LA), —a piston rod extending along the longitudinal axis (LA) in the cavity of the telescopic element, —a force accumulator connected to the piston rod for moving the piston rod in the direction of the longitudinal axis (LA), wherein an intermediate element is provided which is displaceable along the piston rod and along the telescopic segment in the direction of the longitudinal axis (LA) and is fastenable releasably to the piston rod in various positions along the longitudinal axis (LA) and, irrespective of the position on the piston rod, is fastenable releasably in various positions along the longitudinal axis (LA) of the telescopic segment.

Abstract: A positioning device for a telescoping seat post of a bicycle frame includes a tubular telescopic element having a longitudinal axis, a locking device located on an inner surface of the telescopic element, and a tubular supporting element, which is supported in the telescopic element in a rotationally fixed and slidable manner. At least one locking device having at least one locking element is provided and, which can be brought into engagement with the locking device. The locking device has radial grooves, which are arranged in the inner surface of the telescopic element and are bounded in the circumferential direction. The at least one locking element can be actuated by at least one control element.

Abstract: A telescopic seat post for a bicycle frame has a tubular telescopic element for supporting a seat. The telescopic element is mounted so as to be slidable along a longitudinal axis of a seat tube of the bicycle frame. A tubular supporting element is mounted so as to be slidable within the telescopic element, the supporting element has a fastening section that can be connected to the seat tube by a fastener which can be inserted transversely to the longitudinal axis of the seat tube.
