Specialized S-Works Aethos Dura Ace Di2 - Grey

The Specialized S-Works Aethos Dura Ace Di2 has been designed to create the perfect combination of ride quality, lightness, and style - to be able to accelerate even on steep climbs, descend from the most technical descents, and to be comfortable even during long Sunday rides. But you may ask, how was this achieved? The traditional shape of the racing bike from the past has been re-invented, slightly altered to optimize stiffness and balance, without compromising weight or durability. With a completely new lay-up, perfected over many decades, the lightest frame on the market is achieved (585 grams for the S-Works frame size 56). The Aethos is more than just a new bike; it is the beginning of a new generation. An ultra-light frame is useless if the ride characteristics do not inspire confidence. That’s why for the Aethos, the perfect mix of stiffness on the front and rear in relation to ride quality has been sought. By studying the flexibility and every little detail of the carbon fibers, Specialized has learned a lot about how forces travel through the frame. You will only need a few pedal strokes to realize that the Aethos represents a new standard in riding.
