Specialized Aethos II

Break the Rules, the Lightest disc road bike ever made in pursuit of the perfect ride.

The lightest production frameset in its class in pursuit of the perfect ride for more riders.

At just 595 grams, the S-Works Aethos 2 is the lightest production road frame in the world.

And yes, it climbs, corners, and descends unbelievably fast. But it wasn’t built to chase medals or conform to racing’s rules.

Aethos 2 road bike breaks free for something higher.

It’s a portal to the purest ride experience. When effort vanishes, the bike disappears, and body, mind, and machine move as one. And for a timeless moment, all is right in the world.

Now with increased tire clearance and data-based fit-enhancing geometry, it brings that transcendent ride feel to more riders than ever.

Performance inspired fit and handling with 15mm of extra stack. Incredible response at the pedals and up to 35mm Tire clearance.

The Specialized Aethos II designed with a Super Computer and millions of data points. Mixed with intuition and design magic.
Result - The lightest production frameset in its class in pursuit of the perfect ride.


The Aethos 2 breaks the rules. Comfort is Performance.
