The 2026 Specialized Aethos 2 Pro Ultegra 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 Specialized's Cruz and Tarmac SL8 bikes. The Aethos is still the lightest production frame in the world and still has pure and smooth handling.
The Aethos 2 Pro Ultegra Di2 comes with Shimano Ultegra Di2 12 speed electronic gearing and Roval Alpinist CL II carbon wheels along with 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 that's responsive and fun to ride, yet comfortable enough for big days out.

Who are Specialized?
Specialized is one of the best-known quality bike brands in the world. Started by a group of riders in 1974. A fact which has guided their decision making ever since.
" Made for riders, by riders."
They strove to make the best quality tires when quality tyres weren't around. When people wanted to ride cruisers in the dirt, they made the first production mountain bike. When roadies wanted to go faster, Specialized doubled down on carbon and built their own wind tunnel.
Bikes like the Allez, Rockhopper and Stumpjumper have developed followings and reputations of their own. Specialized has a reputation for making high-end, high-quality bikes. Specialized bikes always look great with high-quality paint and sensible sizing hel0s you get the right bike each time. If you buy a Specialized bike you can be guaranteed it will do what it is supposed to and will last.
