2025 S-Works Aethos SRAM Red AXS Road Bike - Satin Doppio/Gunmetal

Season:2025

Brand:Specialized

Code:5432894353987

There is racing, from Grand Tour podiums to the Monument Classics, and then there's riding for the sheer joy of it. This is where the Specialized Aethos Road Bike shines. It's engineered for performance, boasting the lightest frame on the market, without sacrificing style. Aethos: the result of billions of calculations aimed at achieving the perfect ride.

The world's lightest frame is complemented by a full SRAM RED AXS groupset with a power meter, the lightest electronic groupset available, and Roval's ultralight Alpinist CLX II wheels. This combination creates a perfectly balanced, top-tier ride that makes no concessions in performance.

The Aethos frame is designed to offer the ultimate riding experience, combining lightweight construction, exceptional ride feel, and style. Whether you're accelerating up steep climbs, descending technical routes, or enjoying long rides, the Aethos excels. This was acheived by reinventing the traditional road bike shape and making subtle changes that significantly improve stiffness and balance without adding weight or compromising durability. Along with a new layup process refined over decades, Specialized have created the lightest frame (585g, S-Works, size 56cm). The Aethos is not just a new bike; it's a new breed.

A lightweight frame is pointless without reliable ride characteristics, which is why Specialized engineered the Aethos to have perfect front and rear stiffness and exceptional ride quality. By studying the flex and movement of carbon fibre, they made groundbreaking discoveries on how forces flow through frames. Just a few pedal strokes reveal that this ride sets a new standard.

Every detail, from the derailleur hangers to the fork expander plug, is crafted with style, weight, and durability in mind. Specialized have also included Roval's new Alpinist carbon seatpost and wheels to further reduce weight and enhance ride quality. Everything is designed in pursuit of the perfect ride.
