A shock absorber for mounting between a first frame member and a second frame member of a bicycle includes a first member adapted to couple to the first frame member and a second member adapted to couple to the second frame member, wherein the first member and the second member rotate relative to each other. The first member includes a first member protrusion extending inwardly from an inner surface thereof and forming a first border surface at a junction of the first member protrusion and the inner surface. Similarly, the second member includes a second protrusion extending outwardly from an outer surface thereof and forming a second border surface at a junction of the second member protrusion and the outer surface. The first member protrusion faces the second member protrusion in a circumferential direction. An elastic member is disposed between the first member protrusion and the second member protrusion and contacts at least one of the first border surface and the second border surface.
