Aethos: Billions of calculations in pursuit of one thing: perfect driving.

It’s more than just a slogan, it’s a philosophy. The Aethos is designed to balance refined ride quality, extreme lightness and undeniable style, and this Expert model is no exception.

With SRAM Rival Sram Red AXS wireless electronic shifting and hydraulic disc brakes paired with bomb-proof Roval C38 Disc carbon wheels, you’ve got the perfect steed for hitting the road.

• The Aethos frame is designed with the perfect blend of ride feel, light weight, and style from acceleration on steep climbs and technical descents to all-day saddle comfort on even the longest rides, the Aethos hits the mark. But how? By reinventing the traditional shape of road bikes of the past, weve subtly altered these shapes to deliver huge gains in stiffness and balance all without compromising weight or durability. Add to that an all-new layup process weve perfected over decades, and you have the lightest frame on the market (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike its the first of a new class.
• A lightweight frame is nothing without confidence-inspiring ride characteristics, so we developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flex and breathing of carbon fibre, we were able to uncover ground-breaking discoveries about how forces flow through frames. With just a few pedal strokes youll realise that this sublime bike sets a new standard.
• Every detail, from the derailleur mounts to the fork expander plug, has been designed with style, weight, and durability in mind. We also equipped it with Rovals new Alpinist carbon seatpost, which saves even more weight and improves handling characteristics. All in pursuit of the perfect ride.
