The Aethos line promises three thingsextremely light weight, perfectly balanced ride characteristics, and undeniable styleand this Aethos Pro is no exception. Aethos: Thousands of calculations in the pursuit of one thing: the perfect ride.

Equipped with Shimano’s Ultegra Di2 for clean, precise shifting and Roval’s Alpinist wheels mated to DT Swiss 350 axles, you’re left with a no-fuss build that performs, mile after mile.

• The Aethos frame has been designed with the perfect blend of ultimate ride feel, light weight, and style from accelerating up steep grades and descending technical descents, to all-day saddle comfort on even the longest rides, the Aethos hits the nail on the head. But how, you ask? By reinventing the traditional road shape found on bikes of the past, weve subtly altered these shapes to deliver huge gains in stiffness and balance all without compromising weight or durability. Throw in an all-new layup and a process weve perfected over several decades and you have the lightest frame out there (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike its the first of a new breed.

• An ultralight frame is useless without confidence-inspiring ride characteristics, so we developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flex and breathing of carbon fiber, we were able to uncover groundbreaking findings on how forces flow through frames. Just a few pedal strokes and youll realize that this sublime ride sets a new standard.

• Every detail, from the derailleur hangers to the fork expander plug, has been designed with style, weight, and durability in mind. Weve also equipped it with Rovals new Alpinist carbon seatpost and wheels, saving further weight and improving handling characteristics. All in pursuit of the perfect ride.
