Specialized Aethos Pro – Shimano Ultegra Di2 For Sale Online

Break the rules – with the Specialized AETHOS Pro

The new Specialized Aethos Pro promises three things: exceptionally low weight, perfectly balanced handling, and undeniable style. Billions of calculations with a single goal—the perfect ride. And the Aethos Pro is no exception.

The straightforward build, with Shimano’s ULTEGRA Di2 drivetrain for clean and crisp shifts, and Roval’s new Alpinist wheels with DT Swiss 350 hubs, leaves absolutely nothing to be desired, mile after mile.

The Specialized Aethos Pro frame 2025 has been designed with the perfect combination of ultimate ride feel, lightweight, and style—from accelerating up steep pitches and descending technical descents to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, Specialized has subtly altered these shapes to deliver massive gains in stiffness and balance, all while.
A lightweight frame is nothing without confidence-inspiring riding characteristics, which is why Specialized designed the Aethos to offer the ideal combination of front and rear stiffness, combined with great ride quality. Specialized made ground-breaking discoveries on how stresses move through frames by analyzing the bending and breathing of carbon fibers. With just a few pedal strokes, you’ll realize this wonderful ride has set a new benchmark.
Every component, from the derailleur hangers to the fork expander plug, has been created with style, weight, and longevity in mind. Specialized has also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further cutting weight and boosting riding characteristics. Everything in search of the ideal ride.
