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. The S-Works Aethos frame has been designed with the perfect combination of ultimate ride quality, lightweight, and style — from accelerating up steep pitches and taking on technical descents to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. By breaking all the ‘traditional’ manufacturing rules and reinventing the traditional tube shapes found on bikes of the past, we’ve subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that does away with the need for extra stiffness layers, and you have the lightest frame out there (585 grams, S-Works, size 56 cm). A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we’ve developed the S-Works Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we uncovered groundbreaking findings about how forces flow through a frame. With just a few pedal strokes, you’ll realize this sublime ride sets a new standard. Campagnolo has provided its all-new, top-of-the-range Super Record EPS group and Hyperon wheels for this limited edition Aethos. The new 2 x 12-speed group utilizes wireless shifting from the cockpit, new ergonomics, and new shifting logic for smooth, crisp, and fast shifting. A wider gear range and ultra-light Campagnolo Hyperon wheels are the perfect partners for Aethos’ unparalleled climbing ability.
