2023 Specialized Aethos Comp - Shimano 105 Di2 Unisex Road Bike - Satin Carbon

The Aethos Comp is designed to straddle the line between perfect ride quality, extreme lightweight, and undeniable style.

With low-maintenance, Shimano 105 Di2 electronic shifting and hydraulic disc brakes paired with bomb-proof DT Swiss R470 Disc wheels, you have the perfect steed to excite you out on the road.

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. But how, you ask? By reinventing the traditional road shape found on bikes of the past, Specialized have 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 we’ve perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm).

• A featherweight frame is useless without confidence-inspiring ride characteristics, which is why Specialized 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, they were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard.
• Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. Specialized also spec’d it with Roval’s all-new Alpinist carbon seatpost, further saving weight and improving ride characteristics.
