The Aethos line promises three things—exceptional light weight, perfectly balanced ride characteristics, and undeniable 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.

Amazing Frame

I'm amazed at the ride quality of this frame. I was expecting a lot based on videos I've watched and all the reviews I've read but I am blown away with the ride of this frame. It feels like it flows over the road surface. Road vibration and the harsh feel of cracks, etc. is nearly gone with this frame. At the same time it accelerates like a demon. This is not a "soft" frame. The acceleration tells you it is stiff where it has to be to transmit the rider's energy to propel the bike. It also holds speed quite well. I'm using Roval's Alpinist CLX wheels and while they are not as aero as others the combination holds speed very well. At the end of a hard training ride I am fatigued from the effort not from the road. The quality of the build is second to none. It is also very easy to work on. I'm using a mechanical system until next winter so I had to push cables for shifting and braking. It was an easy task to thread the cables/housings through the tubes. Thank you Specialized !
