Specialized Aethos S-Works frame

Don't get us wrong, we're all for racing, it's part of our DNA, but sometimes you ride for the simple pleasure of riding. That's the spirit of the Aethos. We have not compromised on performance, and the Aethos is the lightest bike in its class, but no compromises have been made in terms of style.

This frame is the perfect starting point to create the bike of your dreams.


  • The S-Works Aethos frame was designed to create the perfect combination of ride quality, lightness and style - so you can accelerate up steep climbs, descend technical descents and be comfortable on long Sunday rides. They have re-invented the traditional road bike shape of the past, changing it slightly to optimise stiffness and balance, without compromising weight or strength. With an entirely new lay-up, perfected over many decades, you get the lightest frame on the market (585 grams for the S-Works frame size 56). The Aethos is more than a new bike, it is the beginning of a new generation.
  • A very light frame is of no use if the riding characteristics do not inspire confidence. That's why for the Aethos they looked for the perfect mix of front and rear stiffness in relation to ride quality. By studying the flexibility and every last detail of the carbon fibres, they discovered a lot about how forces flow through the frame. A few pedal strokes are enough to realise that the Aethos represents a new standard of riding.
