The lightest disc road frame ever: The Specialized Aethos

Product Details

Add Icon

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.

And with this frame set, you have the perfect canvas to begin creating your dream ride.

  • 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—everything in pursuit for the perfect ride.

Great Frame and paint

I just purchased the S-Works Aethos frame in SATIN OIL GRANITE OVER METALLIC DEEP LAKE / WHITE SAGE paint. The photos on the website do not do it justice. The colors in person are so amazing. It just depends on how the light hits it. It looks blue then purple then green. WOW what a amazing paint job and to think I almost passed on it. I built the bike up with Alpinest CLX II wheels and SRAM RED components. It's my lightest bike and rides great. I highly recommend this bike.

Best frameset/bike I have ever

Best frameset/bike I have ever owned. It is wonderful at rolling speeds whether you are recovering or setting a new fast pace, but out of the saddle is where this frameset shines - you can almost hear the bike say "Let's do this, I'm all in..."

Yes!

Finally found what I’ve been

Finally found what I’ve been looking for! The S Works Aethos is everything and then some that you’ve heard and hoped it would be. I could not be happier with this bike, I love it! Obviously it is super light but it’s so much more than that. Very comfortable and super fast even with the Alpinist CLX wheelset. It looks awesome and is so much fun to ride! The frame is beautifully designed and the subtle graphics and paint, or lack of on the Jet Fuel option look fantastic. The beautiful aesthetics are a sum of the parts with everything from the thru axles to the top cap complementing the frameset as a whole. The Peter Denk video says it all, the passion that he exudes definitely transcends into the bike that Specialized has built. A guy rode by me last week and commented on how nice my Aethos was and how he almost bought one. All I could do was thank him and think to myself, “worst mistake he ever made”. The S Works Aethos has it all, it is simply awesome!
