Specialized Aethos Pro KH 2023

The Specialized Aethos Pro is a road bike with an ultralight carbon frame and Shimano Ultegra electronic shifting.
The weight saving target is further confirmed by the Roval carbon rims, carbon seatpost and saddle with hollow titanium rails.
No matter how long you’re on the road or how steep the road ahead, you’ll benefit from a seamless driving experience, as well as a high level of efficiency and comfort.
When developing the frame, Specialized used the latest technologies to modify the shapes of the round tubes in such a way as to save superfluous material, achieving an increase in rigidity.
In accordance with the Rider-First-Engineered™ philosophy, the optimal arrangement of carbon in each of the frame sizes was also considered.
