Abstract
Solitary chainring for a bicycle front crank and drive chain, including a plurality of teeth formed thereabout. The plurality of teeth includes a first group of teeth and a second group of teeth alternating with the first group of teeth. Each tooth includes an outer face and an inner face which is opposite the outer face, and each tooth of the first group of teeth includes at least one first protrusion on the outer face or the inner face, and each tooth of the second group of teeth is formed without a first protrusion. The first protrusion is formed by a material deformation on one face of the teeth of the first group of teeth, wherein the material deformation is achieved from the inner face or the outer face, or it is formed by an application of material on one face of the teeth of the first group of teeth.
