Description
Specialized’s 2025 Aethos Pro Force eTap AXS Bicycle exemplifies the Aethos line’s promise of exceptional light weight, perfectly balanced ride characteristics, and undeniable style. Billions of calculations have been devoted to perfecting its ride, resulting in a revolutionary design that reinvents the traditional road bike shape. By subtly altering conventional geometries, the frame achieves remarkable gains in stiffness and balance without compromising durability. Weighing in at an astonishing 585 grams (56cm), the Aethos Pro is not merely a new bike—it represents the first of a new breed.
Paired with top-tier components, the Aethos Pro elevates performance to a new level. It is equipped with SRAM’s intuitive Force eTAP AXS drivetrain that delivers clean, crisp shifts, while Roval’s Alpinist wheels mated to DT Swiss 350 hubs ensure a responsive, no-fuss build. Detailed studies of carbon fiber flexing have enabled engineers to fine-tune the bike’s balance, ensuring that every pedal stroke inspires confidence. Whether accelerating up steep pitches or descending technical descents, riders experience a sublime, race-inspired ride quality.
Every element, from derailleur hangers to the fork expander plug, has been meticulously designed with style, weight, and durability in mind. The incorporation of Roval’s all-new Alpinist carbon seatpost and wheels further enhances the ride while reducing weight. Additional specifications, such as the FACT 10r Carbon frame with Rider First Engineered™ technology, threaded bottom bracket, and hydraulic disc brakes with 160mm rotors, demonstrate Specialized’s unwavering commitment to delivering the perfect ride. Engineered for both performance and aesthetics, every detail perfectly embodies decades of innovation and relentless passion.
