Specialized S-Works Aethos 2 Road Bike (Premium Fjord/Dolomite Metallic) (54cm) (Shimano Dura-Ace Di2)

Specialized S-Works Aethos 2 Road Bike Description:

The Specialized S-Works Aethos 2 Road Bike was built for the needs of those seeking perfection outside the world of racing. Grand Tour top steps, Classic’s Monuments—they’re in the DNA of every bike Specialized produces, but sometimes riding simply to ride, riding for the love of riding, is what fuels the desire to continually push the envelope. And that is what the Aethos lives for. Sure, it’s given nothing up to performance, and happens to be the lightest frame out there, but with no compromise to style. Aethos: Billions of calculations in the pursuit of one thing—the perfect ride.

Top off the world’s lightest frame with Shimano’s legendary Dura-Ace Di2 groupset and Roval’s featherweight Alpinist wheels, and you’re left with a perfectly balanced top-tier ride that gives up nothing in the name of performance.
