The Aethos Frameset gives you the chance to hand-curate the build kit of your dreams.
Manufacturer: Specialized Categories: Bike Frames, Specialized

Aethos is a new name for Specialized — it’s an anthology of every design success they’ve made over the last several decades. The engineers didn’t start with a blank sheet. They began with a wealth of knowledge no other cycling company in the world could match and then went to work subtly altering frame shape, carbon layup, and stiffness and balance to design the greatest riding road bike ever made. And it features the lightest frame ever made.

The Aethos Frameset gives you the chance to hand-curate the build kit of your dreams. The FACT 10r carbon frame features Rider-First Engineering, a threaded BB, and internal cable routing. Thru-axles are found front and rear, and the FACT Fork provides unparalleled compliance without sacrificing stiffness. The frameset also comes with a Roval Alpinist Carbon seatpost to help you slice through the air and remain comfortable on those all-day rides.

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.
Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind—everything in pursuit for the perfect ride.
