Product Info
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.
So Light, It’s a Crime
Aethos began with a moment of human insight: frames “breath” under load. That subtle rhythm revealed how force moved. We fed this into our supercomputer, evolving tubes into sculpted forms. The shape itself delivered stiffness, delivering UCI illegal 5.9kg builds and more responsiveness. The result wasn’t just a more perfect ride, it was a new way of making bikes—Flow State Design.
595 grams FACT 12r Frames - Lighter than the water bottle in your cage thanks to our most optimized layup ever.
To stay under 600 grams and still deliver a ride this sublime, our engineers took our most premium carbon recipe - FACT 12r - and then optimized the layup to an entirely new level. If Aethos 1 was a 10/10, Aethos 2 pushed it to 12. It took countless iterations refining each FACT 12r ply by fractions of a millimeter to unlock a ride closer to perfect than anything that came before.
