2023 Specialized S-Works Aethos Dura-Ace Di2 Unisex Road Bike - Gloss Birch

In pursuit of the sweetest ride on the planet, the S-Works Aethos combines the world's lightest frame with Shimano's Dura-Ace Di2 12 speed groupset and Roval's featherweight Alpinist wheels to create a perfectly balanced top-tier ride that gives up nothing in the name of performance.

• S-Works Aethos FACT 12r Carbon frame/fork just 585 grams!
  
• Full Dura-Ace 12 speed Di2 groupset with powermeter
• SuperlightRoval Alpinist CLX carbon wheelset with 33mm aero profile
• S-Works Turbo tyres 700x28mm
• Bike weight 6kg!

• The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style - from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, Specialized subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that we’ve perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm).
• A featherweight frame is useless without confidence-inspiring ride characteristics, which is why Specialized developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard.
• Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. Specialized also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.
