A chain ring gear set adapted for attaching to spider arms. The spider arms are attached to and extend outwardly from a bicycle gear crank. The ring gear set is adapted for receiving a bicycle chain thereon. The chain is transferred on the ring gear set using a chain derailer. The ring gear set includes a first ring gear disposed next to an adjacent second ring gear in a spaced relationship. A portion of the first ring gear is warped toward the second ring gear for periodically reducing the distance between a perimeter of the first ring gear to a perimeter of the second ring gear. Also, a portion of the second ring gear can be warped toward the first ring gear for sharing or combining the amount of warpage in each gear for reduced chain wear. By indexing the warped portion of the first ring gear with the warped portion of the second ring gear the overall distance periodically is reduced for ease in a smooth chain transfer between the gears.
