2026 Specialized Aethos S-Works Axs

At just 595 grams, this S-Works-level road platform is the lightest production frame in the world—yet outright grams were never the point. Engineered to disappear beneath you, it delivers pure road riding bliss with an impossibly responsive, supple, and balanced feel. By breaking the rules of racing to elevate real-world performance, it brings a transcendent ride quality to more riders than ever, thanks to increased tire clearance, refined components, and data-driven, fit-enhancing geometry.

Whether chasing elevation, carving descents, or floating through all-day endurance rides, this bike blends ultralight efficiency with confident handling and long-mile comfort. Every detail—from the featherweight FACT 12r frameset to the refined cockpit and wheel system—works in harmony for agile acceleration, precise steering, and smooth rolling speed.
