Abstract
A seat post for a cycle has inner and outer members that are slidably mounted together forming a variable volume chamber. The variable volume chamber communicates with a fixed volume chamber in the inner member through orifices and a check valve. Slots are formed in the inner member, and a pin extends from the outer member through the slots. A cushion at one end of the slots prevents hard top-out.
