S-Works Aethos - Dura-Ace Di2

2022 S-Works Aethos - Dura-Ace Di2

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.

Voted Best Brand 5 Years in a Row

#1 Again: 2023 Gran Fondo Awards

The riders have spoken! For the fifth year in a row, Specialized has been crowned the #1 “Drop Bar Bike Brand” in the prestigious Gran Fondo Best Brand Awards for 2023. We innovate for riders, and year after year, our bikes are loved by the most discerning riders. Thank you!

Reinventing Round

Meditating on the breathing and swaying of a bike under load in the lab, lead engineer Peter Denk had an epiphany—true performance lies in the shape, not the material. After a few hundred thousand supercomputer simulations, we knew we were right.

Break the Rules

At just 585 grams, the Aethos frame may be too light for the UCI rule book, but when the pros get a chance to just ride, it’s the Aethos they reach for. Ride along with the World Champ as he takes us up his favorite climb on a very special Aethos.

Aethos x 12 SPD

A bike built for the pure love of riding with the latest electronic 12-spd group from Shimano? Win, win. Faster, more precise shifting with an ultra-efficient drivetrain and a wireless cockpit to help you make the most of your new Aethos.
