Specialized 2026 S-Works Aethos 2 Shimano Dura-Ace Di2 Road Bike

The 2026 Specialized S-Works Aethos 2 Shimano Dura-Ace Di2 Road Bike has been updated with refined geometry for a better fit, improved tyre clearance and new cockpit and wheels. It remains a super light bike built for road purists.

The original Aethos came out of research Specialized did on how carbon frames behave. By feeding their data through a supercomputer they came up with Flow State Design.

This created a new carbon layup which has since become the basis of designs for Specializeds Cruz and Tarmac SL8 bikes. The Aethos is still the lightest production frame in the world and still has pure and smooth handling.

With the S-Works model you get an upgraded FACT 12r frame. The S-Works Aethos 2 Shimano Dura-Ace Di2 comes with Shimano Dura-Ace Di2 12 speed electronic gearing and Roval Alpinist CLX III carbon wheels along with Roval Alpinist handlebars and seatpost.

The all-new Roval cockpit and wheels that are lighter, smoother, and fully integrated into the build. This bike is perfect for Road purists who want a classic, clean looking super light road bike thats responsive and fun to ride, yet comfortable enough for big days out.
