Specialized S-works Aethos Red Etap Axs 2021

Don’t get us wrong we’re all for racing. Grand Tour top steps Classic’s Monuments—they’re in our DNA. But sometimes riding simply to ride riding for the love of riding is just what we need. And this is what the Aethos lives for. Sure it’s given nothing up to performance and happens to be the lightest frame out there but with no compromise to style. Aethos: Billions of calculations in the pursuit of one thing—the perfect ride.
Top off the world’s lightest frame with SRAM’s 12-speed RED eTAP AXS groupset and Roval’s featherweight Alpinist wheels and you’re left with a perfectly-balanced top-tier ride that gives up nothing in the name of performance.
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.
