Telescopic seatpost

A telescopic seatpost for mounting a bicycle saddle, the seatpost comprising:

• a support unit to be fixed to a frame of a bicycle,
• a telescopic unit moveably guided within a predetermined telescopic range relative to the support unit, wherein the telescopic range extends from a minimum longitudinal extent of the seatpost to a maximum longitudinal extent of the seatpost, the telescopic unit having a first end to support a bicycle saddle thereon,
• a coupling device arranged beween the telescopic unit and the support unit, the coupling device including:
• coupling part fixedly connected to the support unit, and the telescopic unit being coupled to the support unit by the coupling device, and
• an adjustment mechanism configured to adjust the maximum longitudinal extent of the seatpost, the adjustment mechanism including an elongated adjustment part having a first end mounted to the first end of the telescopic unit, and the adjustment part being adjustably lockable to the coupling part at a plurality of positions along a longitudinal axis of the adjustment part so as to adjust a distance between the first end of the telescopic unit and the support unit, and thereby adjust the maximum longitudinal extent of the seatpost,
• wherein the coupling device is configured to transmit an axial force acting on the telescopic unit to the support unit, and
• a blocking device configured to releasably block a guided telescopic movement of the telescopic unit relative to the support unit.
