2023 Specialized Aethos Pro Shimano Ultegra Di2 Road Bike - White Sage

Season:2023

Brand:Specialized

Code:396067352652

The Specialized Aethos Road Bike line embodies three core principles, exceptional lightweight design, perfectly balanced ride dynamics, and undeniable style, and the Aethos Pro lives up to this promise without compromise. Aethos: Billions of calculations in the relentless pursuit of one goal, the ultimate ride.

Equipped with Shimano's Ultegra Di2 for precise, effortless shifting and paired with Roval's Alpinist wheels featuring DT Swiss 350 hubs, this build offers a hassle-free experience that delivers mile after mile.

The Aethos frame is meticulously crafted to offer an unparalleled combination of ride quality, featherweight construction, and aesthetic appeal. Whether tackling steep climbs, navigating technical descents, or embarking on leisurely coffee rides, the Aethos delivers on all fronts. Specialized achieved this by reimagining traditional road bike shapes, subtly refining them to enhance stiffness and balance without compromising weight or durability. Combined with a revolutionary layup process honed over decades, the result is the lightest frame available (585g, S-Works, size 56cm). The Aethos isn't just a new bike, it's the herald of a new era.

A lightweight frame is only as valuable as its ride characteristics, which is why the Aethos is engineered to strike the perfect balance of front and rear stiffness while delivering exceptional ride quality. Through meticulous study of carbon fibre flex and behavior, Specialized have uncovered groundbreaking insights into how forces flow through frames. With just a few pedal strokes, you'll recognise that this sublime ride sets a new benchmark.

Every detail, from the derailleur hangers to the fork expander plug, is meticulously designed with a focus on style, weight optimisation, and durability. Additionally, Specialized have equipped it with Roval's innovative Alpinist carbon seatpost and wheels, further enhancing weight savings and ride characteristics. Every aspect of the Aethos is crafted in pursuit of the perfect ride.
