But how, you ask? By reinventing the traditional road shape found on bikes of the past, weve subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that weve perfected over multiple 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.

• A featherweight frame is useless without confidence-inspiring ride characteristics, which is why weve developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and youll realize this sublime ride sets a new standard.
