Break the Rules
With a 705g frame, the Aethos 2 is the lightest bike in its class. But weight was never the point. Built by breaking racing’s rules to deliver pure road riding bliss, it’s engineered to disappear beneath you: responsive, supple, and sublime. Now with increased tire clearance, refined components, 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.
