Break the rules.
With a 705g frame, the Aethos 2 is the lightest in its class. But weight was never the point. Built by breaking racing’s rules to deliver pure road riding bliss, it’s engineered to disappear beneath you: responsive, supple, and sublime. Now with increased tire clearance 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.

The Aethos project began with the human insight that frames “breath” under load. That subtle rhythm revealed how force moved. This information was fed into a supercomputer, evolving tubes into sculpted forms where shape itself delivered stiffness. The result was not just the lightest road bike in its class and a more perfect ride, but a new way of making bikes: Flow State Design.
The Aethos 2 clears 35 mm tires with ease, resulting in smoother, faster rides, more grip, and access to more roads. This bike features the most optimized layup ever, with every detail re-engineered. This approach redefined how bikes are built, a lead followed by the Crux and Tarmac SL8.
Regardless of the bike’s size, every rider gets the famed Aethos ride quality. The fit and geometry were refined using data from over 100,000 Body Geometry fits to make long days in the mountains feel even better. You get precise handling in a more versatile and confidence-inspiring package.
