2025 Specialized S-Works Aethos - Shimano Dura-Ace Di2 Road Bike
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.
