The layer/covering is positioned between the body and the bicycle frame. A retaining structure designed to be fixed adjacent an edge of the seat post receiving opening with a portion extending into the opening to only engage portions of the outer elastomeric layer/covering of the seat post gripper so as to lock the seat post gripper in the seat post receiving opening, whereby the layer/covering of the gripper is positioned between the body of the gripper with the seat post inserted coaxially into the gripper and the bicycle frame.

Abstract: A telescopic position adjustment mechanism allows for a telescoping element to be indexed by fixed increments toward a more telescopically collapsed position, relative to its base. The telescopic position adjustment mechanism uses a stepping reservoir that can, in a stepping configuration, selectively receive a predetermined volume of fluid from a support reservoir that supports the telescoping element against the base, enabling the telescoping element to collapse toward the base by a distance corresponding to the predetermined volume of fluid. In a locking configuration, the volume of fluid in the support reservoir is constant and the telescopic position is fixed, and in a free movement configuration fluid can flow freely between the support reservoir and a sink reservoir to permit free telescopic movement. A rotation resistance mechanism uses a locking key that is biased into engagement with a locking channel to inhibit rotation of the telescoping element relative to the base.

Abstract: A bicycle seat post height adjustment mechanism, in a state of locking, has a lower valve packing ring blocking a lower valve port. Moreover, based on demands, an upper valve packing ring is allowed selectively to block an upper valve port or to be away from the upper valve port to stay on top of the upper valve port. Thus, a pin is driven to axially move down to enable a seat post to make fine adjustment, stepless adjustment or stepped adjustment in height. Moreover, the seat post may self-return to the assigned position (an upper position, a middle position or a lower position) to prevent the height of the seat from altering.

Abstract: Methods and apparatus may permit the mounting of bicycle components (16) such as seats, handlebars, and the like, to bicycles. A bicycle component mount (3) may be isolated from the structure of a bicycle.

A bicycle component mount (3) may exhibit movement about its own center of mass (12). Motions of a rider on a bicycle may be biomechanically compensated for by a bicycle component mount (3) to facilitate rider comfort, promote efficient transfer of rider motion to the operation of a bicycle, and decrease wear on bicycle components (16).

Abstract: A volume spring element 152 is located inside the piston 10 which is open to the cylinder 20. The spring element 152 is surrounded by hydraulic liquid on all sides except at its surface 1521 at which the element 152 is attached to the piston 10. When the hydraulic pressure increases, the volume spring element is compressed thereby decreasing its volume. When the hydraulic pressure decreases, the volume spring element expands again. When the hydraulic cylinder is closed off by a valve, then the hydraulic liquid in the piston 10 and in the cylinder 20 is disposed in a closed-off space or chamber. Axial pressures on the cylinder cause a pressure increase in the hydraulic medium. This causes the volume of the volume spring element to be decreased and the piston to be moved axially by the amount corresponding to the decrease of the equally large oil volume in the piston.
