The new Specialized Aethos promises three things: exceptionally low weight, perfectly balanced riding characteristics, and undeniable style. Billions of calculations with one goal – the perfect ride. The Aethos Pro is no exception. Every detail, from the dropouts to the fork crown, is designed with style, weight, and durability in mind. Specialized has even introduced the brand-new Alpinist seat post and the Alpinist wheelset from Roval to save even more weight and further enhance ride quality. Everything about this bike strives for the ultimate ride. With the wireless electronic SRAM Rival eTap AXS shifting and hydraulic disc brakes, combined with the robust Roval C38 Disc Carbon wheels, you have the perfect vehicle for hitting the road. Frame: FACT 10R Carbon Frame: “Functionally Advanced Composite Technology”; the higher the value, the more complex the production process and the lighter the frame, but also more expensive. The Aethos frame combines the ultimate riding experience, low weight, and unparalleled style. From accelerating on steep climbs to handling technical descents, and providing incredible comfort even on the longest coffee rides – the Aethos hits the mark every time. But how does it achieve this? Specialized has optimized the traditional road bike shape of older models in a completely new way with the help of a supercomputer. The shapes have been subtly altered to provide significant advantages in stiffness and balance without negatively impacting weight or durability. Together with Specialized's completely new and decades-evolved layup process, this has resulted in the lightest frame available (585 g for the S-Works model with a frame size of 56). A feather-light frame is useless without trustworthy riding characteristics. Therefore, Specialized designed the Aethos to have exceptional ride qualities, ensuring that the stiffness within the bike finds the perfect balance. Furthermore, through extensive testing on the flexibility of carbon fibers, Specialized gained groundbreaking insights into how forces distribute within a bicycle frame. After your first few pedal strokes, you’ll realize that the extraordinary handling sets a new standard.
