Aethos 2

Break the Rules



When Aethos launched four years ago, it became the lightest production road bike ever and delivered a ride so incredible, many riders called it perfect. We created this engineering marvel by breaking every rule: our own engineering assumptions, the UCI's weight limits, and the industry's idea of what a modern road bike should be.



But we weren't finished. We were obsessed with making it even better for more riders. So we refined the geometry, equipped it with all-new Roval Alpinist components, and made subtle, but significant improvements.



The result? More Perfect for more riders.



"Perfection is attained not when there is nothing more to add, but when there is nothing more to take away." Antoine de Saint-Exupéry

Technology is Our Tradition.

Aethos 2 is built on the same foundation that redefined what a road bike could be, but with refinements that make it accessible to more riders than ever. Using insights from over 100,000 Body Geometry fits, we tuned the geometry for comfort, stability, and performance without sacrificing the telepathic handling that makes Aethos legendary.



Taller Stack



A 15 mm taller stack eases pressure on hands and shoulders, making long days in the saddle more comfortable. By raising the bar position slightly, riders can stay relaxed and powerful deeper into big days in the mountains.



Longer Wheelbase



A 7 mm longer wheelbase brings confidence at speed. On fast alpine descents or exposed crosswinds, that extra stability translates into smooth, predictable handling without dulling the responsiveness.



Slacker Headtube



A 0.5 degree slacker headtube reshapes steering feel, adding calmness to the front end while keeping the bike razor sharp when pushed hard. The result is smoother control and the confidence to carve harder through corners.



More Clearance, No Compromise



Room for up to 35 mm tires adds comfort, grip, and versatility—without compromise to weight or feel. To stay under 600 grams and still deliver this clearance and the new geometry, our engineers pushed carbon layup further than ever. If Aethos 1 was a 10/10, Aethos 2 pushed it to 12. They visited the factory again and again—refining each ply by fractions of a millimeter. Not just to meet a number, but to unlock the most elegant ride we've ever created.



We didn't just create our most optimized layup ever, we re-engineered every detail, from seat post clap clamp (-9grams), brake mounts (-2grams), BB-Cups (-6 grams) to the UDH derailleur hanger (-2grams) , to maintain the world's lightest disc road frame and deliver complete builds that are even lighter than before.



Flow State Design



Aethos 2 is the culmination of years of research into how frames "breathe" under load. This Flow State Design eliminates unnecessary stiffness layers, creating a lighter, stronger frame that responds instantly to every input.



Effort vanishes. The bike disappears. Rider and machine move as one.



• Refined carbon layup for unmatched durability and ride feel



• Rider-First Engineering delivers perfect handling in every size



• Proven to survive far beyond industry testing standards, even under 2,377 watts delivered over 100,000 pedal strokes
