SPECIALIZED AETHOS PRO SHIMANO ULTEGRA DI2 BIKE 2025
Aethos: countless calculations for one unico purpose, a guida perfetto. This is something more than a motto, it is a vera philosophy. The Aethos has been designed for the connubio perfetto of extreme lightness, exceptional handling and an inimitable style.
The Aethos Pro is equipped with a Shimano Ultegra Di2 drivetrain, Roval Alpinist wheels with DT Swiss 350 mozzi.
- The Aethos frame has been designed to create the combinazione perfetto of ride quality, lightness and style – so you can accelerate even on steep climbs, descend the most technical downhills and be comfortable even during long Sunday rides. But you may ask yourself, how did we do it? We reinvented the traditional forma of racing bikes of the past, changing it slightly to optimize stiffness and balance, without compromising weight or strength. The Aethos is more than a new bike, it is the beginning of a new generation.
- An ultra-light frame is useless if the handling characteristics do not inspire confidence. Ecco why for the Aethos we sought the mix perfetto of stiffness at the front and rear in relation to ride quality. By studying the flex and every tiny detail of the carbon fibers, we discovered a lot about how forces travel through the frame. Just a few pedal strokes will be enough for you to realize that the Aethos represents a new standard of handling.
- Every detail, from the derailleur hanger to the expander on the stem, has been designed with style, weight and strength in mind. We have also included the new Alpinist carbon seatpost to shave off further weight and to optimize the handling characteristics – tutto for the guidabilità perfetto.
