Don’t get us wrong, we’re all for racing. Grand Tour top steps, Classic’s Monuments—they’re in our DNA. But sometimes riding simply to ride, riding for the love of riding, is just what we need. And this is what the Aethos lives for. Sure, it’s given nothing up to performance, and happens to be the lightest frame out there, but with no compromise to style. Aethos: Billions of calculations in the pursuit of one thing—the perfect ride.

And with this frame set, you have the perfect canvas to begin creating your dream ride.

  • The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style—from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, we’ve subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that we’ve perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike, it’s the first of a new breed.

  • A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we’ve developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard.

crazy lightweight climbing machine with tremendous comfort and stiffness

I own a S-Works tarmac SL 7, Cannondale Lab 71 Supersix, and Allez Sprint. This is my go-to bike. It has compliance, stiffness, and great handling. It may not have the sick aero look of SL7 but the ride quality is where its at.

Una sorpresa!

Mi alleno da circa 2 settimane su una bicicletta con questo telaio, gruppo Shimano Ultegra e le mie Mavic Cosmic SLR... mi sono lasciato convincere a comprare questo telaio da un negoziante amico "tradendo" il marchio di biciclette che uso da 20 anni. Ero fiducioso di aver fatto un buon acquisto, ma sinceramente non pensavo di trovare così tanta differenza. Leggera, pronta, scattante, facile da guidare e nervosa come piace a me! Super!

If you can get over

If you can get over the silly price, the Aethos is probably the best road frameset on the market for general riding. No aero nonsense, no crazy integration at the front end, just a lightweight, stiff and comfy frameset that is great for long rides, short blasts and everything in between.

S-Works Aethos

Habe schon einige S-Works Road gefahren aber das S-Works Aethos ist mit Abstand das Beste. S-Works Tarmac fährt sich schon wie auf Schienen. Aber das S-Works Aethos ist der Allrounder. Ob Berg oder Tal einfach mal ausprobieren und man wird überzeugt. Ich persönlich würde es zu 100 % empfehlen. Bin 178 und fahre ein 54 . Mit Sportlichen Gruß I am Specialized

Amazing Ride

I am a 61yo male who now rides recreationally at 6-8,000miles per year. Preferred courses are hilly. In the last 15 or so years have had a Cervelo R3 SL, a Cervelo R5, a Trek Emonda SL and a BMC Roadmachine (my current other road bike). I have also rented a number of different Specialized, Trek, and Pinarello road bikes. Aero frames are of little interest to me. I was intrigued by the Aethos and opted to take the plunge on an S-Works Aethos frame. Built it up with Dura-Ace Di2/hydraulic, Hunt wheels with 28mm Schwalbe Tubeless tires. Have now been riding it for 8+ months with a few thousand miles on it, alternating some with the BMC. Gotta say, this bike's ride is absolutely phenomenal - solid and confidence inspiring on all terrains, especially hilly ones. The other thing is I just love it's understated looks - rode a century and no-one knew what it was! Perfect! Easily my favorite ever ride - The Aethos just makes me smile every time I ride it!
