Product Details

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.

The Satin Carbon/Jet Fuel colorway is the lightest finish we offer on an S-Works Aethos Frameset. It’s also the perfect canvas if you are craving custom paint. This is our RTP—Ready To Paint—colorway, allowing you imagine the build, colors, and design of your dreams, then work with a custom painter to make it a reality.

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.
The Satin Carbon/Jet Fuel colorway is ready to ride as is but features logos that are decals over a clear coat, so they can be easily removed if you choose to work with a custom painter. The frameset includes a second set of decals to be applied after painting. Keep in mind that when you modify the paint and/or graphics on your Aethos, the limited warranty provided by Specialized will no longer cover your paint and graphics. Any issues related to such modifications should be worked out between you and your custom painter.
