Product Details
The Specialized Aethos frameset is a masterpiece of engineering that promises three core elements—exceptional lightness, perfectly balanced ride characteristics, and an undeniable sense of style. With billions of calculations dedicated to achieving one goal—the perfect ride—the Aethos frameset serves as the ultimate foundation for building your dream bike.
This frameset is meticulously crafted to deliver an unmatched combination of ride feel, light weight, and sleek aesthetics. Whether you're powering up steep climbs, navigating technical descents, or enjoying long days in the saddle, the Aethos frameset ensures every ride is an extraordinary experience. The secret lies in its innovative design, where traditional road bike shapes have been subtly reimagined to provide significant gains in stiffness and balance without compromising on weight or durability. This is complemented by a revolutionary layup process, perfected over decades, resulting in a frame that is not only incredibly light—tipping the scales at just 585 grams (size 56cm)—but also robust and resilient. The Aethos isn't just a new frame; it represents the dawn of a new era in cycling.
A lightweight frame alone isn’t enough; it must also inspire confidence on the road. That's why the Aethos frameset has been engineered to achieve the perfect balance of front and rear stiffness, paired with exceptional ride quality. By meticulously studying the behavior of carbon fiber under different stresses, Specialized has made groundbreaking discoveries about how forces interact within the frame, resulting in a ride that feels incredibly responsive and stable. A few pedal strokes are all it takes to understand that the Aethos sets a new benchmark for road bikes.
Every aspect of the Aethos frameset, from the derailleur hangers to the fork expander plug, has been thoughtfully designed with style, weight, and durability in mind, all in pursuit of creating the perfect ride.
