S-Works Aethos - Dura-Ace Di2

Delivery Icon

We deliver! Just say when and how.

Don’t get us wrong, we’re all for racing. Grand Tour top steps, Classic’s Monuments—they’re in our DNA. But sometimes riding simply to ride, riding for the love of riding, is just what we need. And this 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.

Awesome bike - never stop smiling !

Yes this bike is light, and it doesn’t look overly like many more angular modern road bikes but you wait until you ride it. It handles like a dream & for sure its lightness helps on the hills. I marvel every time I ride mine at its effortless sure footed cornering and that it’s just such a huge pleasure to ride. Don’t think about it any longer - go on, take the plunge & get yourself one. You will truly never stop smiling!!!

Inspiring

Yes; I read all the reviews, saw all the videos, but its only when I actually rode it that I really understood what Specialized have achieved here. It hearkens back to my childhood days when I first learn to ride a bike without the help of side wheels. With a big silly grin pasted on my face and the sensation of effortless freedom, I can tell you that this bike is not about KOM's or TT's or even winning races. In fact, if my GPS unit could measure Fun instead of Wattage, it would max-out on my every ride. For once; its all fun and games. No regrets.
