Bicycle shock-absorbing apparatus

A bicycle shock-absorbing apparatus (10) clamped in a steerer crown (2) which is engaged to a steer tube (1) of a bicycle by a sleeve (3) and a C-clip (4) comprising a lower tube (20) having an upper cavity and a mount member (201) thereunder and an upper tube (16) partially and slidably received within said cavity of said lower tube (20), a rod means (5) having a cap portion (50) and a rod member (51) downwardly extending from said cap portion (50), said cap portion (50) being engaged to an upper end of said upper tube (16), a bellows (12) being engaged on a top end of said lower tube (20) and also slidably receiving a portion of said upper tube (16), a bellows (12) being engaged on a top end of said lower tube (20) and also slidably receiving a portion of said upper tube (16), said upper tube (16) and said bellows (12) being clamped by said steerer crown (2), a plurality of compressive units (7) being arranged longitudinally inside said upper tube (16), said rod member (51) of said rod means (5) penetrating through said compressive units (7), said cap portion (50) downwardly facing a top one of said compressive units (7), a socket bolt (17) having an upper socket (171) with a flange portion (174) and a lower bolt member (172), a channel (173) being defined from said upper socket (171) down to said bolt member (172), said lower bolt member (172) being engaged to said mount member (201) causing said compressive units (7) to be limited between said cap portion (50) of said rod means (5) and said upper socket (171) of said socket bolt means (17), said upper tube (16) slidable holding said compressive units (7) and said upper socket (171) of said socket bolt means (17), a lower socket member (19) being engaged to a lower end of said upper tube (16) while allowing said lower bolt member (172) to slide therethrough, a first cushion (18) being positioned between said lower socket (19) and said flange portion (174) of said upper socket (171) of said socket bolt means (17), such that when said bicycle receives a shock from an uneven terrain causing said steerer crown (2) to move downward, which in turn causes said upper tube (16) to slide downward in said lower tube (20), compressing said compressive units (7), and causes said rod member (51) of said rod means (5) to move downward in said channel (173) of said socket bolt (17).
