ABSTRACT:
A cushion assembly for a bicycle seat includes a tubular member securely mounted to a bicycle seat tube, a seat post partially received in the tubular member and having an upper end to which a bicycle seat is attached, a spring received in the tubular member and having an upper end on which the seat post rests and a lower end abutting against a bottom of the tubular member, a bolt extending from an outside of the bottom of the tubular member through the receptacle to engage with the seat post to move therewith, thereby allowing vertical movements of the seat post in the tubular member. First and second clamp plates are mounted between the tubular member and the seat post and each have a contour complimentary to that of an outer periphery of the seat post, thereby preventing relative rotational movements between the seat post and the tubular member. The tubular member has a plurality of holes defined in a periphery thereof, providing an access to the second clamp plate. A second bolt is adjustably mounted to each of the holes to adjust a position of the second clamp to bear against the seat post. A gap between the tubular member and the seat post, which may be enlarged due to abrasion after a term of use, is reduced to an acceptable manner by turning the second bolts to urge the second clamp plate to bear against the seat post.
