A joint is used for a bicycle frame. The joint includes a composite material first tubular member, and a metal second tubular member fitting having a laterally extending insertion portion. A coating is made of the same composite material as that of the first tubular member and is applied to the entire fitting, except for the end portion of the insertion portion. The first member is sleeved on and adhered to the end portion of the insertion portion and contacts the coating. The abutting surfaces of the coating and the first member are of the same outer and inner diameters so that the joint looks like a unitary composite material frame. |
