2024 Specialized Aethos Comp Shimano 105 Di2 Road Bike - Pine - Size 54cm

Season:2024

Brand:Specialized

There's riding, there's racing, there's training, there's competing but the Aethos is all about riding for the love of riding. The Aethos is designed to straddle the line between perfect ride quality, extreme lightweight, and undeniable style. The Aethos Comp model is no exception.

Equipped with low-maintenance Shimano 105 Di2 electronic shifting, hydraulic disc brakes, and paired with the robust DT Swiss R470 Disc wheels, it's the ultimate companion to ignite your passion on the open road.

The Aethos frame strikes the perfect harmony between supreme ride feel, weightlessness, and aesthetics, whether conquering steep climbs, navigating technical descents, or embarking on leisurely coffee rides, the Aethos delivers. Specialized achieved this by reimagining traditional road bike shapes, subtly tweaking them to amplify stiffness and balance, all while maintaining a featherweight build without compromising durability. Enhanced by a groundbreaking layup technique perfected over decades, it boasts the lightest frame available (585g, S-Works, size 56cm). The Aethos heralds not just a new bike, but a new era in cycling.

Yet, a lightweight frame alone is meaningless without confidence-inspiring ride dynamics, which is why the Aethos achieves an optimal balance of front and rear stiffness alongside exceptional ride comfort. Through meticulous study of carbon fibre's flex and response, Specialized have unearthed revolutionary insights into force transmission within frames. Just a few pedal strokes unveil this sublime ride experience that sets a precedent anew.

Every component, from the derailleur hangers to the fork expander plug, is meticulously crafted with an eye for style, weight optimisation, and longevity. Specialized have even integrated Roval's innovative Alpinist carbon seatpost to further enhance weight savings and ride quality. Every detail, every decision, converges in the pursuit of cycling perfection.
