Aethos Pro


The Aethos line promises three things: unprecedented weight savings, perfectly-balanced ride quality, and undeniable style. For the Aethos Pro Specailized threw out the rulebook to create the ride of your life.

Spec’d with Shimano’s tried-and-true Ultegra Di2 electronic shifting to deliver clean, crisp shifts and Roval’s Alpinist wheels mated to DT Swiss 350 hubs. This is a no-fuss build that delivers, mile after mile.

  • 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, Specailized 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 they’ve 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 Specailized 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. Specailized also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.
