This invention relates to a carbon fiber bicycle rim and its molding method, belonging to the reinforcement technology of carbon fiber rims. Specifically, it includes a technique that integrates a metal wire (steel wire) into a sidewall of a carbon fiber rim body to enhance impact resistance and deformation resistance of the rim.

A two-piece wheel may have a first section and a second section. The wheel has areas of varying diameter across its width, and the first second and the second section are joined at the area of the wheel with the smallest diameter. The first section can be a spoke section with spokes extending from the central hub and the second section can be a barrel section.
