The lightest disc road frame ever: The Specialized Aethos

Product Details

Add Icon

What if we used every ounce of experience we’ve gained serving riders over the past 46 years and built a bike made simply for the love of riding? The Aethos is designed to straddle the line between perfect ride quality, extreme lightweight, and undeniable style. The Aethos Comp model is no exception.

With low-maintenance, Shimano 105 Di2 electronic shifting and hydraulic disc brakes paired with bomb-proof DT Swiss R470 Disc wheels, you have the perfect steed to excite you out on the road.

  • 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, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.

This thing goes

Lightweight, mighty comfortable, and easy to handle. If you are looking for all these things, Aethos is the way to go!

Super nice for an old man with great legs 50+ miles a week

Takes one finger to lift. 18 lbs on the scale without pedals. Just purchased but have 150+ miles on it. Added glued on tires to cut down on flats. Purchased a new pump to keep better inflation. Tested 5 other bikes before this one--and stopped after the first lift. Still getting used to the electronic shifters. Looking forward to a softer seat. But I recommend that you give this sweet bike a ride. Favorable to my Cannondales: CAAD10 and CX10 and Criterium.

Best Bike I've Owned

I wanted to upgrade from my 08' Tarmac and debated the new Tarmac or the Aethos for almost a year. I'm nearly 50, but still love fast race bikes, but i dont want my fillings to raddle out of my teeth. In the end, the Aethos reviews commonly state how fun the Aethos is, so I chose the Aethos and I am so glad I did. This is a very fast bike, it rolls with ease and loves it when you get out of the saddle, and bombs descents with rock-solid stability. The part that amazes me the most is how comfortable it is to ride. It eats road vibration, but doesn't feel disconnected or sluggish. How did they do that? I don't know, but I'm glad they did. I've only put about 300 miles of cold winter riding on this bike, but on every ride thus far, I've caught myself smiling and laughing at each new revelation about the Aethos. It is fast, comfortable and fun. Plain and simple. I got the entry level Aethos Comp - Shimano 105 Di2 and am very happy with the bike and components
