The Road Bike Redefined for Pure Riding Pleasure
The Aethos Expert is the ultimate expression of balance on the road. By combining an ultra-light carbon frame with carefully tuned tube shapes, it achieves a ride quality that’s as smooth as it is responsive. High-end Ultegra Di2 shifting, durable yet light Roval carbon wheels, and refined geometry come together so seamlessly, you’ll forget about the bike and focus entirely on the joy of the ride. Whether climbing alpine passes or cruising scenic country lanes, the Aethos Expert empowers you to ride farther, faster, and more comfortably than ever.
Key Benefits to You as a Rider (Feature → Benefit):
- FACT 10r Carbon Frame: Its precise layup creates an ultra-light, stiff chassis that delivers crisp acceleration for effortless climbing and agile handling for confident cornering.
- Roval C38 Carbon Wheels: These light, aerodynamic wheels minimize rotational mass, letting you maintain speed with less effort and descend with unwavering stability.
- Shimano Ultegra Di2 Drivetrain: Electronic shifting provides instant, reliable gear changes, ensuring you always find the perfect cadence to conserve energy and ride more efficiently.
- Endurance-Inspired Geometry: Slightly relaxed angles and balanced fit reduce fatigue over long rides, so you stay comfortable and powerful as miles turn into memories.
The Bottom Line: The Aethos Expert is a ride that disappears beneath you, leaving nothing but the thrill of cycling’s purest form—just you, the road, and the freedom to explore.
