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.
  • 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.

Don't want to sound cliche, but this Aethos is the best bike I have ever ridden.

From the start, I was pretty excited when this model was released with its classic lines, round tubes, ample tire clearance and the ability to use mechanical cable shifting. I built up my Aethos in 2021 when the world had gone crazy and had to wait about three months for the abalone white colorway to finally arrive in stock. I'm running full SRAM Red, ENVE cockpit and ENVE 4.5AR wheels that are wrapped with ENVE 29c tires. The smoothness and comfort of the frame is unparalleled for long days in the saddle. Even with some pretty heavy wheels, it climbs exceptionally well. To say this bike rides like a dream is an understatement. I can only imagine this is how a magical genie feels riding a magical carpet.

One of the finest riding bikes I have ever ridden! Remarkable bike for someone desiring a light and smooth ride.

Former cat1/2 rider with 35 years of riding experience and this bike is amongst the finest bikes I have ridden. It is very light, well damped and efficient, snappy and responsive in the turns without harshness over road irregularities and chatter and yet feels stiff. I can hammer all I want, pushing in the corners, sprinting in heavy gears, or ripping up hills, I never feel like there is a loss of power transfer or energy. This bike has a fantastic ride quality, I can ride FAR longer than any other bike I owned and feel fresh despite the distance. It’s ridiculously light and looks fast sitting still. I think its the best looking bike I have seen in years. Makes me feel 20 years younger! I feel this bike is best used as a goto bike for club rides, century’s and days when all you want to do is ride and melt away stress and tension having fun for the joy of turning them cranks. If you can afford to or find one, do yourself a favor and get one! You won’t regret it.
