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.
So Light, It's a Crime - Complete Builds at Just 5.9kg Thanks to Flow State Design.
Aethos began with a moment of human insight: frames "breath" under load. That subtle rhythm revealed how force moved. Specialized fed this into their 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.
Geometry and Fit Perfected for More Riders
Decades of Body Geometry data, now tuned into a fit that works for more riders than ever.
Specialized refined the fit and geometry using data from over 100,000 Body Geometry fits to make long days in the mountains feel even better. Climb faster. Descend harder. Ride longer. You get precise handling in a more versatile and confidence-inspiring package.
More Versatility. More Clearance. No Compromise. No Gram was Safe from The Scalpel.
Aethos 2 clears 35 mm tires with ease. That means smoother, faster rides, more grip, and more roads. That kind of upgrade usually comes at a cost. Not here. Specialized didn't just create their most optimized layup ever, they re-engineered every detail. No gram was safe from the Specialized Science Club's obsession.
