Abstract: The present invention is an improved construction for joining chainstays with a bottom bracket shell in a bicycle frame. The construction consists of a pair of taper-shaped projecting parts of a bottom bracket shell, inserting portions of chainstays placed around the projecting parts and a connecting ring provided with a pair of taper-shaped connecting holes. The connecting ring is placed around the joining part of the bottom bracket shell and chainstays and joins the bottom bracket shell and chainstays together by the bonding strength of an adhesive agent and a screw from the connecting ring to the bottom bracket shell. The adhesive agent is uniformly spread between the bottom bracket shell and chainstays and should the adhesive agent become ineffective, the chainstays will not loosen from the bottom bracket shell due to the screw.
