Built by breaking racing's rules, the bike is designed to be responsive, supple, and sublime—engineered to disappear beneath you.\n\nThe Aethos 2 now offers increased tire clearance, refined components, and data-based fit-enhancing geometry that brings the transcendent ride feel to more riders than ever. It combines performance road riding capability with a performance endurance fit, making it accessible to a broader range of cyclists.\n\n\u003cdiv data-section-type=\"hero-banner\" data-theme=\"white\" data-align-h=\"left\" data-align-v=\"center\" data-text-align=\"left\" data-content-max-width=\"470\"\u003e\r\n\u003ch3\u003eSo Light, It’s a Crime\u003c\/h3\u003e\r\n\u003cp\u003eAethos began with a moment of human insight: frames “breath” under load.
