Hardy built the Zephrus Ultralite rod with their patented Sintrix 440 technology, which is an advanced kind of resin which surrounds each carbon fiber with microscopic silica spheres to increase strength by 60% and reduce weight by 30% when compared to traditional carbon fiber. This rod is designed for ultra-delicate presentation with a fast action to give you a powerful cast, and a high recovery rate. This lightweight rod is resetting the standard for strength of rods in its class, moving the industry forward.
