2023 S-Works Aethos Dura-Ace Di2 Road Bike - Gloss Obsidian/Lapis

Season:2023

Brand:Specialized

Code:349961349432

There is the thrill of competitive racing, conquering Grand Tour stages or claiming victory in cycling classics and then there's a pure joy in riding simply for the sake of riding. It's a sentiment that resonates deeply with the essence of the Specialized Aethos Road Bike. This machine is built not only for unrivaled performance but also for an unbridled love of the ride itself. Despite being the lightest frame available, the Aethos makes no compromises when it comes to style.

Pairing the world's lightest frame with Shimano's renowned Dura-Ace Di2 groupset and Roval's featherweight Alpinist wheels creates a harmonious, high-performance ride that leaves nothing to be desired.

The Aethos frame embodies the perfect fusion of ride feel, weightlessness, and aesthetic appeal. Whether conquering steep inclines, navigating technical descents, or embarking on leisurely coffee rides, the Aethos delivers an exceptional experience. This achievement is made possible through a revolutionary redesign of traditional road bike shapes, enhancing stiffness and balance without sacrificing weight or durability. With a meticulous layup process honed over decades, the Aethos boasts an astonishingly low weight of 585g (S-Works, size 56cm), marking the dawn of a new era in cycling.

However, a lightweight frame is only as valuable as its ride quality, which is why the Aethos strikes a perfect equilibrium between front and rear stiffness while delivering an unparalleled riding experience. By delving into the intricacies of carbon fibre flex and behaviour, Specialized have uncovered groundbreaking insights that redefine ride standards with every pedal stroke.

Every aspect of the Aethos, down to the smallest details like derailleur hangers and fork expander plugs, is meticulously crafted with a focus on style, weight optimisation, and durability. Complemented by Roval's innovative Alpinist carbon seatpost and wheels, the pursuit of the perfect ride is evident in every element of the Aethos.
