Specialized S-Works Aethos 2 Dura-Ace Di2 Road Bike 2026

The Specialized S-Works Aethos 2 Road Bike is the lightest road bike ever produced, but its purpose is not medals or rules. It was created to free the rider, delivering a pure and timeless riding experience where effort disappears and rider and machine move as one.

S-Works Aethos 2 Refined Geometry

The Aethos 2 refines geometry, increases tyre clearance, and introduces new Roval components while retaining the sublime ride feel that defined the original. Every improvement was made to extend the experience to more riders without compromise.Drawing on decades of Body Geometry data, the Aethos 2 offers a fit that suits more riders than ever. A taller stack, longer wheelbase, slacker head tube, and lower bottom bracket combine for stable handling, greater comfort, and improved control.

SpecializedFlow State Design

Born from the discovery of how frames flex under load, Flow State Design optimises tube shapes rather than adding stiffness layers. The result is a lighter frame with improved ride quality, greater structural integrity, and unmatched durability.

SpecializedAethos 2 Greater Clearance

The Aethos 2 clears 35 mm tyres with ease, adding versatility and comfort without increasing weight. Achieving this required an entirely new carbon layup, perfected through countless refinements for the most elegant ride yet.

Roval Alpinist Components

The updated Alpinist cockpit and wheels complement the Aethos perfectly. At just 270 g, the Alpinist Cockpit II is more ergonomic, comfortable, and responsive, while the Alpinist CLX III wheels are lighter, stronger, and more durable.

SpecializedAethos 2 Lightness with Strength

Despite its feathery weight of 705 g, the frame endures testing far beyond industry standards, withstanding over 100,000 pedal strokes at 2,377 watts without issue. Lightness meets strength in perfect balance.
