Ride for the love of it with the Specialized Aethos Road Bike. The lightest frame on the market combines style and performance. Paired with Shimano Dura-Ace Di2 groupset and Roval Alpinist wheels for the ultimate ride. Experience the perfect balance of weight, stiffness and style for your next adventure.

Don’t get us wrong—we’re all about racing. The Grand Tours, the Monument Classics—those victories are part of our DNA. But sometimes, it’s not about the race. Sometimes, it’s about riding just for the sheer joy of it. And that’s where the Aethos comes in. It’s built to perform, sure, and it’s the lightest frame out there, but it’s designed with style and passion, too. The Aethos is the result of billions of calculations, all aimed at achieving one thing: the perfect ride.

Outfitted with the world’s lightest frame, the Aethos is paired with Shimano’s legendary Dura-Ace Di2 groupset and Roval’s ultralight Alpinist wheels. The result? A perfectly balanced, high-performance machine that doesn’t sacrifice anything in the name of speed, weight, or style.

The Aethos frame combines exceptional ride feel, minimal weight, and striking style. Whether you're powering up steep climbs, diving into technical descents, or enjoying a long, laid-back ride, the Aethos checks all the boxes. How do we achieve that? By reimagining traditional road bike geometry, subtly tweaking frame shapes to improve stiffness and balance, all while keeping weight and durability in perfect harmony. With a new layup process honed over decades of expertise, we’ve crafted the lightest frame out there—just 585 grams (S-Works, size 56cm). The Aethos isn’t just another bike; it’s a game-changer.

But a light frame means little if it doesn’t deliver confidence-inspiring performance. That’s why we’ve engineered the Aethos with the perfect balance of front and rear stiffness, ensuring an exceptional ride that’s both responsive and comfortable. By studying how carbon fibre flexes and responds to force, we’ve uncovered insights that redefine how a frame should behave. Ride it, and you'll immediately understand why this bike sets a new standard.

Every detail, from the derailleur hangers to the fork expander plug, has been designed with an obsessive focus on style, weight, and durability. We've also equipped the Aethos with Roval’s new Alpinist carbon seatpost and wheels, saving even more weight while improving ride quality. Every element is carefully crafted in the pursuit of the perfect ride.

Unlock a cost-effective way to own the bike of your dreams through the Cycle to Work Scheme. This initiative, available to employees in the UK, lets you enjoy the benefits of cycling while saving on your bike purchase.
