Product Information

Specialized S-Works Aethos SRAM Red eTAP AXS Disc Road Bike


Introducing the Aethos, Specilaized's lastest development that brings you a totally new breed of bike, one that allows you to experience a new world where you get to ride amongst the clouds with the lightest frame in the world. We all love racing, from the Grand Tours to the local crit races, it's just simply in our blood and that's a given but what we sometimes forget, what sometimes slips our mind in amongst the everyday hussle and bussle is that before we loved racing, before we pushed ourselves to be better, faster, stronger, we loved to ride simply for the love of riding. So Specialized decided to break the rules, throughout the hundreds of UCI templates they've moulded, and create the Aethos, a bike that captures riding in it's purest form. The Aethos blends the rider and bike into one as harmouniously as possible, creating a world where time just doesn't exist when you're in the saddle. With a frame that's close to the weight of a feather, just 585 grams, you're all set to dance up those climbs like never before, accelerate and explode into a breakaway that no one can cover with unmatchable control and the most graceful of handling as you take your speed down into the descent. But Specialized didn't just stop with the frame and it's top of the range ride quality, they saw every fine detail through till the end, till it was nothing short of perfection. They equipped this Aethos with SRAM’s 12-speed RED eTAP AXS groupset for the most blissful shifting possible as well as Roval’s Alpinist wheelset for a ride you'll never forget, and neither will anyone who tried to ride with you... Specialized even designed the fork expander plug with fine detail to keep it lightweight, durable and smart. Specialized's puriest creation we've ever seen is here.



Full Specification



A New Breed

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, Specialized has 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 Specialized has 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.


Ride Quality 

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 Fine Detail 

Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. Specialized also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride. Top off the world’s lightest frame with SRAM’s 12-speed RED eTAP AXS groupset and Roval’s featherweight Alpinist wheels and you’re left with a perfectly-balanced top-tier ride that gives up nothing in the name of performance.
