S-Works Aethos 2 Frameset

What Our Gearhead® Experts Are Saying:

"I love the Aethos 2 because it keeps the effortless handling of the original but adds meaningful updates—more tire clearance, better fit geometry, and improved stiffness balance. The 12r carbon layup is incredibly responsive, and the threaded BB and hidden cable routing make it a dream to build. It’s the perfect foundation for a high-end road setup focused purely on ride quality."

The S-Works Aethos 2 Frameset pushes lightweight engineering to its limits, achieving a 595-gram frame without compromising stiffness, durability, or ride feel. Its FACT 12r carbon construction is tuned to deliver maximum responsiveness while preserving torsional suppleness, creating a road feel that behaves intuitively under hard acceleration, quick descents, and long endurance miles. The updated geometry enhances rider positioning while preserving the lively, natural handling that made the original Aethos a standout.

Technical refinement is found throughout the chassis. The 12x100/12x142 thru-axle standard ensures precise alignment and braking performance, while the integrated headset with CeramicSpeed SLT bearings provides ultra-smooth steering. A BSA threaded bottom bracket improves long-term serviceability, and hidden cable routing keeps the build clean whether running mechanical or electronic drivetrains. Increased tire clearance adds versatility for rough pavement and endurance events.

For riders building a premium performance road machine with an emphasis on feel over race regulations, the Aethos 2 is unmatched. It thrives on steep mountain ascents, winding descents, and all-day road exploration where minimal weight and maximum ride quality make the difference.
