Aethos 2 Frameset

What Our Gearhead® Experts Are Saying:

"I’ve built a few dream road bikes around this frameset, and every time I’m reminded why the Aethos exists. It’s absurdly light, sure, but what stands out is how balanced it feels on long climbs and fast descents. The threaded BB, clean cable routing, and generous tire clearance make it easy to build exactly how you want, without any compromises for modern components."

We’re always chasing that perfect road ride—the one where the bike disappears beneath us and the miles feel effortless. The Aethos 2 Frameset delivers exactly that sensation. From long alpine climbs to quiet backroad descents, it feels impossibly light yet grounded, encouraging us to ride farther, climb higher, and savor every mile. Specialized designed the Aethos 2 for riders who love the purity of road cycling, not just racing results.

Built from FACT 10r carbon, the Aethos 2 Frameset combines cutting-edge engineering with a classic road feel. Rider First Engineered geometry ensures consistent ride quality across all sizes, while Flow State Design shapes the tubes for stiffness and compliance without excess material. With clearance for up to 35mm tires, a threaded bottom bracket, and flat-mount disc compatibility, it’s a modern platform that still prioritizes simplicity and ride bliss.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
