Experience the ultimate ride with the Aethos bike.
The Aethos is designed to straddle the line between perfect ride quality, extreme lightweight, and undeniable style. The Aethos Sport model is no exception. The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style—from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark.
By reinventing the traditional road shape found on bikes of the past, subtle alterations have been made to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process 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, it’s the first of a new breed.
A featherweight frame is useless without confidence-inspiring ride characteristics, which is why the Aethos has been developed to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, groundbreaking findings about how forces flow through frames have been discovered. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard.
Features:
- Featherweight frame at 585 grams (S-Works, size 56cm).
- Perfect balance of front and rear stiffness.
- Exceptional ride quality.
- Roval's all-new Alpinist carbon seatpost for weight saving and improved ride.
- Designed with style, weight, and durability in mind.
