Saddle support for two-wheeler i.e. mountain bike, has closing element that is designed such that closing element connects external tube and internal tube in force-fitting or form-fitting manner, in closing position

摘要

The support has an internal tube (4) that is adjustable opposite to an external tube (2). A separate piston (6) is arranged between the tubes and limits a positive area (8) and a negative area (10) in sections. A closing element (38) is designed such that the closing element connects the external and internal tubes in a force-fitting or form-fitting manner, in a closing position. The positive and negative areas are connected with one another by a pressurizing agent channel (68) that is lockable by the closing element. The external tube is formed as a frame part of a two-wheeler.
