The Specialized Aethos S-Works Dura Ace DI2 Road Bike (2023)—a true racer's dream machine, but with a twist! This bike is all about embracing the joy of riding just for the sake of it.

Sure, it's designed for dominating the Grand Tours and Classic Monuments, but it's also built to relish every pedal stroke purely for the love of the ride. So, whether you're conquering the world's most challenging races or simply cruising around town with a smile on your face, the Aethos will be your trusty companion, delivering top-tier performance without holding back on the FUN factor. Get ready to experience the ride of a lifetime with the Specialized Aethos S-Works Dura Ace DI2 Road Bike—because who says you can't have it all?

Features

  • 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, we’ve 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). 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 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 fiber, we 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. 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.
