Specialized S-Works Aethos Dura Ace Di2 Road Bike

The Aethos epitomizes the joy of cycling, embracing the essence of riding for the sheer love of it while maintaining peak performance. As the lightest frame available, it seamlessly integrates Shimano’s revered Dura-Ace Di2 groupset and Roval’s Alpinist wheels to create a top-tier ride experience without compromise. Crafted with meticulous attention to detail, the Aethos strikes the perfect balance between ultimate ride feel, lightweight design, and impeccable style, delivering unmatched comfort and performance whether navigating steep climbs or leisurely coffee rides.

Behind its featherweight construction lies a groundbreaking approach to frame design, leveraging innovative shaping techniques and decades of expertise to enhance stiffness and balance without adding bulk. Engineered for confidence-inspiring ride characteristics, the Aethos achieves a harmonious blend of front and rear stiffness, coupled with exceptional ride quality derived from in-depth studies of carbon fiber behavior. From derailleur hangers to fork expander plugs, every element is thoughtfully crafted to optimize style, weight, and durability. Further enhancing its prowess are Roval’s Alpinist carbon seatpost and wheels, meticulously selected to elevate performance and save weight. In the pursuit of the perfect ride, the Aethos stands not just as a new bike, but as the vanguard of a transformative era in cycling excellence.
