Abstract: There is described a bicycle seat post assembly in which the travel distance of the seat post can be adjusted. The seat post assembly includes an outer tube that is configured to telescopically receive an inner tube. The inner tube is axially slidable relative to the outer tube between a retracted position and an extended position, the extended position being determined by an extension assembly in which an inner contact member engages an outer contact member, thereby setting the upper limit of axial extension of the inner tube. The extension of the inner tube can be limited to an intermediate position that lies between the retracted and extended positions by an insertable shim that is positionable between the inner and outer contact members.

Abstract: An arrangement 10 includes at least one straight rod 11 which is connected to the saddle support frame or to the support 20 carrying the saddle support frame. The arrangement 10 prevents rotation of the saddle about the longitudinal axis of the support 20 and limits the stroke of the support in the rearward inclined tube of the cycle frame and therefore fixes the highest elevation to which the saddle can be adjusted. The arrangement also prevents theft of the assembly comprising the saddle and its support. In a case of a closed frame, the arrangement 10 includes a U-shaped rod defined by two legs on respective sides of the transverse tube 32 of the cycle frame. The U-shaped rod includes a bight portion 17 which connects the two lower ends of the rod 11. The bight portion 17 limits the stroke of the support 20 and makes theft of the assembly of saddle and support difficult.

The outer surface of the post and the inner surface of the sleeve being made of compatible plastics exhibiting sufficient lubricity to permit sliding movement of the post relative to the sleeve thereby minimizing wear of the inner surface of the sleeve and the outer surface of the post.

Abstract: A shock absorbing bicycle seat mounting post assembly is mounted in a hollow tubular socket member, by means of a binder clamp, in the frame of a bicycle. The shock absorber includes a compression spring which will effectively absorb shocks which are carried through the frame when the wheels encounter obstacles and holes when traveling along the ground. The bicycle seat mounting post assembly includes a number of shims which will adapt the post assembly to varying sizes of bicycle frames. A bellows is provided to keep dirt and dust out of the spring area and protect skin and fingers from being pinched. Stabilization is enhanced by the provision of a piston at the lower end of the movable shaft upon which the seat is attached. A variable volume reducing device may be positioned below the seat mounting post to adjust the volume of air trapped below the piston.
