The Aethos line promises three things—exceptional light weight, perfectly-balanced ride characteristics, and undeniable style—and this Aethos pro is no exception. Aethos: Billions of calculations in the pursuit of one thing—the perfect ride.

Spec’d with Shimano's Ultegra Di2 that delivers clean, crisp shifts and Roval’s Alpinist wheels mated to DT Swiss 350 hubs and your left with a no-fuss build that delivers, mile after mile.

  • The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style—from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape 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 we’ve perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike, it’s the first of a new breed.

  • A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we’ve developed the 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 were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard.

  • Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. We’ve also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride

Low Maintenance

I ride my aethos practically everyday. And in Portland that means rain and grit 9 months out of the year. With a little TLC after each ride, the bike has been just about maintenance free. So fast and responsive. My cat weighs more than the bike!

vélo exceptionnel pour la montagne

Un rendement et un confort exceptionnel. Certes, le vélo est cher, très cher en particulier pour les versions haut de gamme, mais impossible d'être déçu par ses performances en montagne. J'ai réussi à gagner 5% de performance vs mon autre vélo, lui aussi dans les mêmes gammes de prix. Un petit bémol toutefois : les freins à disques qui frottent régulièrement et qui nécessitent des réglages réguliers Dommage qu'aucune version ne sorte en frein à patin

Un vélo de route précis, performant avec un comportement sans comparaison

Souhaitant compléter ma pratique Gravel avec un vélo de route, je voulais un vélo facile, confortable mais aussi performant. Mon vélociste m'a alors conseillé à partir des principaux critères de ma pratique et nous sommes arrivés sur l'Aethos. Je roule dans une région géographiquement assez plate mais j'aime les côtes et la montagne. Le vélo est performant, il m'emmène confortablement "au train" sur des sorties solo au long cours et quand la vitesse s'élève en groupe il répond présent avec une belle nervosité. Mais c'est dans les bosses qu'il s'exprime le mieux, le train roulant avec les Roval Alpinist est un véritable bonheur. L'Aethos vous emmène facilement vers les sommets quelque soit l'allure. Si on appuie un peu (comme j'aime) on vole et "The sky is just the limit". Ce n'est pas une gageure, c'est du vécu car le vélo ne demande qu'a accélérer en côte. Côté design j'apprécie sa simplicité et l'épure des tubes ronds qui le rendent unique. Un très bon investissement pour ma part.

The perfect performance road bike for the non-racer.

If you're not chasing the marginal gains that an aero road bike will yield, look no further than the Aethos. This bike is as responsive and agile as a Tarmac, while also being lighter. The new 12 speed Ultegra is a noticeable improvement over it's predecessor. Shifting is faster and smoother, and the drivetrain is nearly silent. The extra cog is nice as well.
