Racing tyres usually trade durability for speed — thicker protection means more rolling resistance. Panaracer claims to have avoided that trade with the Agxero, its first full redesign of the Agilest line in four years: a nylon taffeta shield structure lifts puncture resistance 6% over the outgoing tyre, while ultra-fine 0.14mm casing cords keep the density up and the rolling resistance down. It's built for riders who don't want to choose between flat protection and a fast tyre, in either clincher or tubeless-ready form.
