SPECIALIZED AETHOS 2 EXPERT SHIMANO ULTEGRA Di2

The Specialized Aethos 2 was born with a precise objective: to offer the highest possible ride quality, without compromise and without following the traditional logic of competition bikes. With a frame weighing only 705 grams, it is one of the lightest bikes in its category, but lightness is only one part of its identity.

The Aethos 2 is designed to deliver pure sensations on the road: beneath the rider, it almost seems to disappear, thanks to fluid, responsive, and incredibly refined handling. Every detail of the frame has been studied to achieve the best balance between stiffness, comfort, and maneuverability, with an immediate response to pedaling and excellent stability on descents.

The increased wheel clearance, optimized components, and Rider First Engineered™ geometry allow every size to offer the same riding sensations, perfectly adapting to cyclists of every build. The result is an extremely light, balanced, and fun bike, conceived for those who love to ride for the pure pleasure of the road.

The Aethos 2 breaks the rules of competition to focus on what truly matters: the riding experience.
