Aethos: The Lightest Road Bike Frame Ever Built—Designed for the Perfect Ride
At the heart of cycling lies passion—and the Specialized Aethos is built for riders who crave that pure, unfiltered joy of the ride. Yes, racing is in our blood—Grand Tour victories and Classic Monuments prove that—but the Aethos road bike is about more than just speed. It’s about balance, beauty, and freedom. It’s about building your dream machine from the most advanced road bike frame ever made.
This is the lightest road bike frame on the market—just 585 grams (S-Works, size 56cm)—without sacrificing stiffness, ride quality, or durability. It’s not just revolutionary in weight—it’s a new breed of performance road bike.
Create Your Dream Road Bike with the Aethos Frameset
This carbon fiber road bike frame is the ideal starting point to build a road bike that’s uniquely yours. Whether you're chasing KOMs, crushing climbs, or clocking long-distance weekend rides, the Aethos frameset offers the ideal combination of weight savings, sleek design, and precise handling.
Performance Meets Innovation
So, how did we do it? By reengineering traditional road bike geometry and refining carbon layup techniques over decades, we unlocked massive performance gains. The result is an ultralight carbon frame with superior stiffness, balance, and long-term durability.
Unlike many lightweight bikes, the Aethos doesn’t compromise on comfort. From steep climbs to high-speed descents to all-day endurance rides, it delivers buttery-smooth handling and exceptional responsiveness.
Engineered for the Ultimate Ride Quality
A featherweight frame means nothing without confidence on the road. That’s why every detail of the Aethos road frame is built for ride perfection. By studying how carbon fiber flexes and breathes under pressure, our engineers discovered groundbreaking insights into force distribution across the frame.
The outcome? A road bike that feels alive—responsive in the corners, stable on descents, and silky-smooth over long distances. Every pedal stroke on the Aethos feels effortless and efficient.
Every Detail Refined
From the derailleur hangers to the fork’s expander plug, every component of the Aethos is optimized for style, weight, and performance. It’s precision engineering in pursuit of one thing: the perfect ride.
Key Features:
- Lightest production carbon frame (585g)
- Revolutionary stiffness-to-weight ratio
- Reimagined traditional frame shapes for balance & durability
- Designed for long-distance comfort and high-performance climbing
- Ideal base for a dream custom road bike build
Looking for the best road bike frame to start your dream build? The Specialized Aethos sets a new standard. It's not just a frame—it’s the foundation of a ride you’ll never forget.
