The lightest production road bike in the world, a bike built for the pure love of riding, the latest S-Works Aethos LTD is breaking the rules all over again. A celebration of Specialized heritage, only 300 of these individually numbered bikes will ever be made available worldwide. Each is unique with hand-dipped paint, and each is built with the all-new Campagnolo Super Record EPS group and Hyperon Wheels. The S-Works Aethos LTD with Campagnolo Super Record EPS raises the bar on what high-end road bike can be.Creating the lightest production road bike frame in the world – 585 grams – took every ounce of our 49 years of experience, so it’s a fitting canvas to celebrate the founding of Specialized. In 1973 it was a love of riding that inspired Mike Sinyard to sell his VW bus, pack up his bike, and go ride in Italy. It was on that trip that Mike fell in love with the quality, the beauty, and the ride of Italian components. He made it his mission to bring them to riders in the US, and Specialized Bicycle Components was born. Combining the Aethos with the pinnacle of Italian components pays homage to Mike’s love of riding and Italy’s riding culture.
