The invention relates to a positioning device (40) for a telescoping seatpost (1) of a bicycle frame (17), comprising: a tubular telescopic element (3) having a longitudinal axis (LA) and having a locking means (30) located on an inner surface (I) of the telescopic element (3), a tubular supporting element (4), which is supported in the telescopic element (3) in a rotationally fixed and slidable manner, at least one locking device (24) having at least one locking element (28), which can be brought into engagement with the locking means (30), wherein the locking means (30) has radial grooves (80), which are arranged in the inner surface (I) of the telescopic element (3) and are bounded in the circumferential direction, wherein the at least one locking element (28) can be actuated by means of at least one control element (27), wherein at least one redirecting means (33) redirects the motion of the control element (27) along the longitudinal axis (LA) into a motion transverse to the longitudinal axis (LA) and transmits the motion to the at least one locking element (28), which is in contact with the redirecting element (33), and the at least one locking element (28) can thereby be brought into or out of contact with the locking means (30) in a direction radial to the longitudinal axis (LA). |
