The 2023 Specialized Aethos Pro Shimano Ultegra Di2 Road Bike promises three things; exceptional light weight, perfectly-balanced ride characteristics, and undeniable style.

The Aethos is the result of billions of calculations in the pursuit of one thing; the perfect ride. 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, Specialized have subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability.

The Aethos Pro comes with Shimano's Ultegra Di2 that delivers clean, crisp shifts and Roval’s Alpinist wheels mated to DT Swiss 350 hubs for a no-fuss build that delivers, mile after mile.


This bike is perfect for

Road riders who want a classic lightweight bike with the latest electronic gearing.


Key Features
  • A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we’ve 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 fibre, we were able to discover ground-breaking 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. We’ve 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
