S-Works Aethos Frameset - FACT 12R Carbon

The Aethos is designed for riders who love the pure experience of cycling. It combines race-proven performance with exceptional ride quality and refined aesthetics, offering nothing less than the perfect canvas for building your dream road bike. The frame achieves its legendary lightness through reinvented traditional road geometry and an entirely new carbon layup and manufacturing process perfected over multiple decades. At just 585 grams for a size 56cm S-Works frame, the Aethos is among the lightest frames available, yet maintains full stiffness and durability without compromise. The Aethos delivers the perfect balance of front and rear stiffness combined with exceptional ride quality. Through extensive study of how carbon fiber flexes and breathes, Specialized discovered groundbreaking insights about force flow through frames. This results in a sublime ride that sets a new standard, whether accelerating up steep pitches, descending technical terrain, or enjoying all-day comfort on long rides. Every detail has been meticulously designed with style, weight, and durability in mind—from derailleur hangers to fork expander plugs—all in pursuit of the perfect ride.
