Specialized Aethos Pro

The Aethos focuses on ride quality rather than aerodynamic optimization. By reinventing traditional tube shapes and focusing on how force flows through the frame, Specialized achieved a exceptionally lightweight chassis that feels lively and balanced without sacrificing stiffness.

Yes, this model is equipped with a 4iiii Precision 3+ power meter integrated directly into the Shimano Ultegra crankset, allowing you to track your performance metrics immediately without needing aftermarket upgrades.

Yes, the Roval Alpinist CL II wheels are tubeless-ready. They come paired with S-Works Turbo 2BR tires, which are designed to be set up tubeless for better puncture protection and a smoother ride quality.

The Aethos uses a standard Shimano threaded BSA bottom bracket. This is generally preferred by mechanics and riders alike for its reliability, ease of service, and tendency to remain creak-free compared to many press-fit alternatives.

The 12-speed Ultegra Di2 groupset provides crisp, precise, and consistent electronic shifting. It is highly reliable in all conditions and offers the same performance benefits as the top-tier Dura-Ace groupset, just with a slight weight penalty.

Absolutely. While it is a performance-oriented bike, the Aethos is engineered for a 'sublime' ride quality that excels on long days in the saddle. Its geometry and carbon layup are designed to reduce road vibration and fatigue, making it a great choice for long climbs and technical descents.
