Specialized Aethos 105 Di2 Road Bike 2025

With 46 years of rider-focused experience, we present the Aethos—a bike crafted solely for the love of riding. This model is designed to skillfully balance perfect ride quality, extreme lightweight, and undeniable style, exemplified by the Aethos Comp.

The Aethos frame embodies the pinnacle of riding experience, seamlessly combining ultimate ride feel, lightness, and style. Through innovative redesign, we've altered traditional road shapes, achieving significant gains in stiffness and balance without compromising weight or durability. With a groundbreaking layup process perfected over decades, the Aethos road bike boasts the lightest frame available (585 grams, S-Works, size 56cm), marking the dawn of a new era in biking. It's not just a new bike; it's the inception of a new breed.

A featherweight frame is meaningful when paired with confidence-inspiring ride characteristics—a balance of front and rear stiffness, coupled with exceptional ride quality. Our meticulous study of carbon fiber flex and breathing has led to groundbreaking insights, setting a new standard in sublime rides. Every detail, from derailleur hangers to the fork expander plug, reflects our commitment to style, weight, and durability. The inclusion of Roval’s all-new Alpinist carbon seatpost further enhances weight savings and ride attributes, emphasizing our relentless pursuit of the perfect ride.
