S-Works Aethos 2 – The lightness that makes you forget the bike

Weighing just 595 grams, the S-Works Aethos 2 frame is the lightest production road frame in the world. But the numbers are just the beginning: this bike is designed to disappear beneath you and leave you with nothing but the pure pleasure of riding.

The Aethos 2 was created by breaking the rules of traditional race bikes, to offer you an incredibly natural ride: responsive when you sprint, smooth on long distances, stable on the most technical descents. The new geometry, optimized with real rider data, guarantees a more precise fit that is accessible to an even greater number of riders.

The increased tire clearance lets you run wider tires for superior comfort and control, while every component has been refined to enhance lightness without sacrificing stiffness and efficiency.

Whether you’re an experienced cyclist or an enthusiast dreaming of the ultimate bike, the S-Works Aethos 2 redefines the concept of a road bike: zero compromises, just love for the ride.
