The Aethos frame was designed to combine style and performance while being ultralight. From uphill accelerations, technical descents to long days in the saddle, it can do it all. How? We reinvented classic tube shapes by optimizing them for stiffness and handling while maintaining their weight advantage. Add to that a new carbon manufacturing process and all our years of experience, and you get a 585 gr frame (SW size 56 cm). The Aethos is not just a new bike, it's the first of a new category.
