2024 Specialized Aethos Pro Ultegra Di2, Satin Red Sky/Red Onyx

The Aethos line promises three things - exceptional light weight, perfectly-balanced ride characteristics, and undeniable style. Spec’d with Shimano's Ultegra Di2 that delivers clean, crisp shifts plus includes a power meter and Roval’s Alpinist wheels mated to DT Swiss 350 hubs and your left with 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. Specialized have subtly altered frame tube 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's been perfected over multiple decades and you have the lightest possible frame.
• 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. It's also spec’d with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride
