Introducing the Aethos line: Where Exceptional Light Weight, Perfectly Balanced Ride Characteristics, and Undeniable Style Converge
The Aethos frame offers the ultimate ride feel, light weight, and style, making it perfect for steep climbs, technical descents, and all-day comfort. Through innovative design, we've enhanced stiffness and balance without compromising weight or durability, resulting in the lightest frame on the market (585 grams, S-Works, size 56cm).
Confidence-inspiring ride characteristics define the Aethos, striking the perfect balance between front and rear stiffness for an exceptional ride quality. Our in-depth study of carbon fiber flexing and breathing has led to groundbreaking insights, setting a new standard in sublime riding experiences.
Every detail of the Aethos, from derailleur hangers to fork expander plugs, is meticulously crafted with a focus on style, weight, and durability. It's not just a new bike—it's the first of a new breed, redefining the pursuit of the perfect ride.

Founded in California in 1974, Specialized began with a simple promise: serious riders deserve serious gear. Half a century later, the brand still funds its own wind tunnel, builds its own carbon, and tests every bike with the world's best so that you ride your own best.
The first production mountain bike. The first cycling-specific shoes. FACT carbon, the Win Tunnel, S-Works. Specialized has a habit of building the things the rest of cycling ends up copying.
