The Specialized Aethos Comp Road Bike: Crafted for the Love of Riding

Imagine channeling over 46 years of cycling expertise into creating a bike purely for the joy of riding. The Specialized Aethos Road Bike embodies this vision, balancing exceptional ride quality, ultra-lightweight design, and striking style. The Aethos Comp model is a standout example of this commitment.

  • Precision Engineering: Equipped with reliable Shimano 105 Di2 electronic shifting and powerful hydraulic disc brakes, the Aethos Comp ensures smooth, low-maintenance performance. Paired with durable DT Swiss R470 Disc wheels, this bike is built to inspire confidence on every ride.
  • Innovative Frame Design: The Aethos frame perfectly blends ride feel, minimal weight, and style. By reimagining classic road bike shapes, Specialized have achieved significant improvements in stiffness and balance without adding weight or compromising durability. Thanks to a new layup process refined over decades, the Aethos features one of the lightest frames available, weighing just 585g (S-Works, size 56cm).
  • Unmatched Ride Experience: The Aethos is engineered for all types of rides, from steep climbs and technical descents to long, comfortable days in the saddle. Specialized's deep understanding of carbon fibre dynamics allowed Specialized to create a frame with the perfect balance of front and rear stiffness, delivering an unparalleled riding experience.
  • Attention to Detail: Every component of the Aethos, from the derailleur hangers to the fork expander plug, is meticulously crafted with style, weight, and durability in mind. The bike also features Roval’s new Alpinist carbon seatpost, reducing weight and enhancing ride quality for the ultimate cycling experience.

The Specialized Aethos Comp Road Bike is more than just a bicycle, it's the beginning of a new era in cycling, designed to deliver perfection with every ride.
