Model Summary
At just 595 grams, the S-Works Aethos 2 is the lightest production road frame in the world. But that was never the point. Built by breaking the rules of racing to deliver pure road riding bliss, Aethos 2 is engineered to disappear beneath you — impossibly responsive, supple, and sublime. Now with increased tyre clearance and data-based, fit-enhancing geometry, it brings that transcendent ride feel to more riders than ever. Aethos 2 breaks the rules, for the love of the ride.
Key Highlights
- World's lightest production road frame: 595 grams (size 56cm) of S-Works-level FACT 12r Carbon construction, without giving up an ounce of ride quality.
- Flow State geometry update: 15mm more stack, a 7mm longer wheelbase, a 0.5° slacker head angle, and a 3mm lower bottom bracket than the original Aethos deliver a more confident, all-day ride feel while keeping that signature Aethos liveliness.
- CeramicSpeed SLT headset bearings: near-friction-free steering precision straight out of the box.
- Increased tyre clearance: up to 700x35mm, a jump from the 32mm of the original S-Works Aethos, for a smoother ride on rough roads.
- Threaded BB and UDH dropout: a quiet, serviceable BSA threaded bottom bracket paired with a SRAM Universal Derailleur Hanger for maximum drivetrain compatibility.
- Turnkey S-Works frameset package: includes the Roval Alpinist carbon seatpost and fully integrated headset — a genuine "just add groupset" canvas for your dream build.
