Accidentally Illegal

Accidentally Illegal

We broke the rules of manufacturing to create ride quality beyond imagination. To do it, we had to create the lightest production road frame ever made - just 585 grams. If you hold a UCI license, our S-Works Aethos is too light to race, so our apologies. To everyone else, you’re welcome.

Unparalleled Ride Quality

Unparalleled Ride Quality

By studying the flexing and breathing of carbon fiber, we uncovered groundbreaking findings about how forces flow through a frame. This new understanding unlocked another level of ride quality and confidence. Attack a climb, rail a descent, and in just a few pedal strokes, you’ll feel the difference.

With the S-Works Aethos LTD featuring all-new Campagnolo Super Record Wireless and its hand-dipped paint, we’re celebrating the vital role that our passion for Italian craftsmanship played in the founding of Specialized Bicycle Components in 1974. Only 300 of these one-of-a-kind bikes will ever be made available worldwide.

The lightest disc road frame ever: The Specialized Aethos

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.

Aethos S Work LTD

J’aime le cadre mais pas le nouveau groupe Campagnolo j’ai donc fait changer ce groupe par le dernier dura ace Di2 plus compatible avec les braquets que j’ai l’habitude de tirer ça ne change rien au comportement exceptionnel de ce cadre qui est bon dans tous les cas montée,plat,sprint. De plus sa polyvalence et son confort permet de faire de longues sorties sans problème car son confort est exceptionnel. J’ai donné cinq étoiles pour le cadre pour le reste chacun peut monter ce cadre à son goût. Encore bravo aux ingénieurs et techniciens Specialized .

Lovely bike

I was very much surprised by how well the Campagnolo Super Record Wireless groupset works after all the bad reviews online. Gets way too much hate. The rear deraileur literally shifts like a dream, almost too quick. My only complaint about this bike is the weight. Size 54 weighed in at 6.8kg. Very disappointing, as many reviews show that 56 sized frames are well below the 6.8kg range. I suspect the white paint and Campy group have something to do with it, as the wheels are light as a feather. Overall cannot complain as I did not pay full price. Handles extremely well, and tackles climbs beautifully.
