Telescopic seat post for bicycle

Abstract

A telescopic seat post for a bicycle includes inner and outer tubes, a pneumatic cylinder inserted in the inner and outer tubes, and a closing set. The outer tube is provided at the bottom end thereof with an installation portion. The inner tube is telescopically inserted in the outer tube. The pneumatic cylinder is provided at the top end thereof with a control stem. The bottom end of the pneumatic cylinder is located in the installation portion. The closing set includes an elastic supporter and a rigid supporter. One of the elastic and rigid supporters is removably installed in the installation portion to provide an upward supporting force to the pneumatic cylinder. As a result, the telescopic seat post is selectable between having shock absorption effect and having no shock absorption effect by the rider through component replacement, and the component installation and replacement is easy.
