2026 Specialized S-Works Aethos 2 Shimano Dura-Ace Di2
Break the Rules
At just 595 grams, the S-Works Aethos 2 is the lightest production road frame in the world. But that was never the point. Built by breaking the rules of racing to deliver pure road riding bliss, Aethos 2 is engineered to disappear beneath you. Impossibly responsive, supple, and sublime. Now with increased tire clearance, refined components, and data-based fit-enhancing geometry, it brings that transcendent ride feel to more riders than ever. Aethos 2 breaks the rules, for the love of the ride.
