S-Works 2021 Aethos Frameset
The 2021 S-Works 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, Specialized has 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 perfected over multiple decades and you have the lightest frame out there. The Aethos is more than just a new bike, it’s the first of a new breed.
- Perfect balance of front and rear stiffness combined with exceptional ride quality
- (585 grams, size 56cm)
- 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.
