The Specialized Aethos Pro Road Bike Frameset is built for riders who value pure performance, simplicity, and the joy of the ride. Crafted from Specialized’s premium FACT 10r carbon, it delivers exceptional stiffness-to-weight with a ride quality that feels effortlessly smooth and responsive. The Aethos is designed around classic, round-tube aesthetics—blending timeless style with cutting-edge engineering to create one of the lightest disc-brake road frames ever made. Its geometry strikes a perfect balance between agility and comfort, making it equally suited for long climbs, fast descents, and all-day rides. Refined, featherlight, and built for feel as much as speed, the Aethos Pro frameset is road cycling distilled to its purest form.
