An exceptionally light road frameset built for the simple joy of a brilliant ride.
The S-Works Aethos 2 Frameset is made for riders who value responsive handling, all-day comfort and a bike that seems to disappear beneath them. Its 595 g FACT 12r carbon frame, matching carbon fork and Roval Alpinist seatpost provide a remarkably light foundation for a truly personal road build.
Lightweight by Design
At a claimed 595 g, the FACT 12r carbon frame is exceptionally light. But the Aethos 2 is not just about the numbers: every part of the chassis is engineered to create a lively, natural ride feel that makes climbs, corners and long days on the road more enjoyable.
Responsive Yet Supple
The Aethos 2 balances direct, precise handling with the compliance needed for real roads. It feels eager when you accelerate and composed when the surface gets rough, making it a road bike that rewards both hard efforts and unplanned detours.
Performance Endurance Fit
Data-informed Performance Endurance geometry gives the Aethos 2 a balanced position for long rides without losing the efficient, connected feel of a performance road bike. Increased tyre clearance also gives you more freedom to tailor comfort and capability to the roads you ride.
Ready for Your Dream Road Build
The included Roval Alpinist seatpost complements the lightweight chassis, while the frameset format lets you choose the wheels, groupset, cockpit and tyres that suit your riding best.
