摘要
A bicycle upper rear fork unit (1) comprises a one-piece body (10) and presents a fork (13) connected to a lower rear fork unit (4) of the bicycle, the upper fork unit (1) having a tubular end portion (12) arranged to cooperate with a saddle connection element (5) connecting the fork unit (1) to the remaining portion of the bicycle frame (2), the one-piece body (10) presenting a substantially triangular portion (15) interposed between the tubular portion (12) and the arms (14) of the fork (13). The saddle connection element (5) receives within one of its parts the tubular end portion (12) of the upper rear fork unit (1), said terminal portion (12) projecting from the said part of the saddle connection element (5) for a maximum distance of 2 centimeters measured from that vertex (17) of the triangular portion (15) close to the tubular portion to ensure a high resistance to rear flexural and torsional stresses.
