Model Summary
With the S-Works Aethos Frameset, you have the perfect canvas to build the ride of your life. Rather than chasing wins or convention, Specialized set out to create the greatest expression of ride quality, reinventing the traditional road frame shapes found on bikes of the past to deliver a meaningful step up in stiffness and balance without adding weight. Built in S-Works FACT 12r carbon, the result is one of the lightest production road frames ever made — light enough to transform steep pitches and technical descents, yet balanced enough for all-day comfort on the longest rides.
Key Highlights
- S-Works FACT 12r Carbon construction: an ultra-light frame (585g claimed, size 56) built from an entirely new carbon layup developed to maximise stiffness and ride quality without adding weight.
- Reinvented road frame shaping: subtly altered tube shapes deliver a meaningful step up in front and rear stiffness and balance over traditional road frames.
- Threaded BSA bottom bracket: a 68mm threaded shell keeps the build simple, reliable, and easy to service.
- Roval Alpinist seatpost and headset included: the frameset arrives ready to build, complete with a carbon seatpost, headset with carbon spacers, and thru-axles.
- Up to 32mm tyre clearance: room to run wider road tyres for extra comfort and grip without sacrificing the frame's race-oriented geometry.
