Product Details
The Aethos prioritizes the joy of riding over racing, embodying the pursuit of the perfect ride without compromising on performance or style. It stands as the lightest frame, meticulously crafted through billions of calculations for an unparalleled experience.
This top-tier ride pairs the world's lightest frame with Shimano's Dura-Ace Di2 groupset and Roval's Alpinist wheels, achieving a harmonious balance of performance and quality. The Aethos redefines traditional road shapes, enhancing stiffness and balance without compromising weight (585 grams, S-Works, size 56cm). More than a new bike, it heralds a new era in cycling—a featherweight frame delivering confidence-inspiring ride characteristics, seamlessly blending front and rear stiffness with exceptional ride quality. Every detail, from derailleur hangers to the fork expander plug, is meticulously designed for the perfect ride, complemented by Roval's Alpinist carbon seatpost and wheels to further elevate the experience.
