Specialized Aethos 2 Pro (SRAM) Performance Road Bike 2026
Specialized Aethos 2 Pro (SRAM) Performance Road Bike 2026
Break the Rules
With a 705g frame, the Aethos 2 is the lightest bike in its class. But weight was never the point. Built by breaking racing’s rules to deliver pure road riding bliss, it’s engineered to disappear beneath you: responsive, supple, and sublime. Now with increased tire clearance, refined components, and data-based fit-enhancing geometry, it brings that transcendent ride feel to more riders than ever. Aethos 2 breaks the rules, for the love of the ride.
So Light, It's a Crime
The Lightest Road Bike In it's class, Thanks to Flow State Design
Aethos began with a moment of human insights: frames "breath" under load. That subtle rhythm revealed how force moved. We fed this into our supercomputer, evolving tubes into sculpted forms. Shape itself delivered stiffness. The result wasn't just the lightest road bike in its class and a more perfect ride, it was a new way of making bikes - Flow State Design.
Geometry and Fit Perfected for More Riders
Decades of Body Geometry data, now tuned into a fit that works for more riders than ever.
We refined the fit and geometry using data from over 100,000 Body Geometry fits to make long days in the mountains feel even better. Climb faster. Descend harder. Ride longer. You get precise handling in a more versatile and confidence-inspiring package.
