The Aethos frame is designed with the perfect combination of maximum ride feel, lightness and style: from accelerating up steep inclines and descending the most technical roads, to all-day saddle comfort on even the longest coffee runs, the Aethos hits the mark.
By reinventing the traditional road bike shape you find on bikes of the past, we've subtly altered these shapes to offer massive gains in stiffness and balance, all without affecting weight or durability. Coupled with an entirely new layout and process that we've perfected over several decades and you'll have the lightest frame ever (585 grams, S-Works, size 56 cm). The Aethos is more than a new bike, it's the first of a new generation. A lightweight 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 about how forces flow through frames. Just a few pedal strokes and you'll find that this sublime experience sets a new standard. Every detail, from the derailleur hanger to the stem cap, has been designed with style, weight and durability in mind, all in pursuit of the perfect ride.
