What if we used every ounce of experience we’ve gained serving riders over the past 46 years and built a bike made simply for the love of riding? The Aethos is designed to straddle the line between perfect ride quality extreme lightweight and undeniable style. The Aethos Sport model is no exception. With low-maintenance Shimano 105 mechanical shifting and hydraulic disc brakes paired with bomb-proof DT Swiss R470 Disc wheels you have the perfect steed to excite you out on the road. 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 further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.
