A seat rail for a bicycle seat and a method of fabricating same are disclosed. The seat rail comprises a rod having one or more flutes formed along the length of the rod. The seat rail provides support for a bicycle seat and provides means for securing the seat to the frame of a bicycle. The flutes in the rod reduce the effective cross-sectional area of the rod which results in a significant decrease in the weight of the seat rail, but without a significant loss of rigidity and strength. The fabrication method comprises providing an elongated rod-shaped feedstock, forming at least one flute along the length of the rod-shaped feedstock, and then bending the fluted feedstock to form the seat rail.
