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.
