Aethos 2 Frameset

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. Shape itself delivered stiffness. The result wasn’t just the lightest road bike in its class and a more perfect ride, it was a new way of making bikes - Flow State Design.

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. We didn’t just create our most optimized layup ever, we re-engineered every detail. No gram was safe from the Specialized Science Club’s obsession.
