INTRODUCING AETHOS

BREAK THE RULES

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? When we set out on this project, we promised ourselves that we would make a bike that elevated the moments when human and machine become one, when we lose ourselves dancing up a climb or carving through a turn. Well, we did it, and in keeping that promise, we broke every design, ride, and race rule along the way. And we’re not sorry.

WE THREW OUT THERULEBOOK TO CREATE

THERIDE OF YOUR LIFE

FOR ONCE, WE’RE NOT IN ITTO WIN

We stopped worrying about winning, or the way things are supposed to be done, and instead chased the greatest expression of ride quality ever made. On the way, we broke the “rules” of carbon manufacturing, and we broke the unwritten “rules” of riding. Oh and by the way, at just 585 grams, it’s the lightest production disc frame ever made—we broke those sacred UCI rules too. It’s a revolution born of inspiration.

AETHOS (AY-THOSS)

BILLIONS OF CALCULATIONS

ONE EPIPHANY

An almost out of body test lab experience birthed Aethos. Meditating on the breathing and swaying of a bike under load in the lab, lead engineer Peter Denk had an epiphany when he realized that true performance lies in the shape, not the material. After a few hundred thousand supercomputer simulations, we knew we were right.

LET’S FLIP THE SCRIPT

“HEY, CARBON! SHAPE UP!”

A frame’s shape is what drives the vast majority of a bike’s performance. Through our obsessive simulation, we learned that tubes with subtle, elongated conical sections - aka our Continuous Curvature Design strategy - deliver the highest stiffness-to-weight ratio ever tested. Turns out the obsessive Germans at the Zedler Institute agree with us.

NO LAZY FIBERS

This discovery of shape driving performance then gave us the opportunity to improve the ride quality delivered by material and layup. We were able to eliminate traditional stiffness layers, reducing the plies necessary to build the bike by 11% compared to a Tarmac SL6. Utilizing longer, unbroken plies, every fiber is structural and reduces weight substantially. This ensures that the only thing along for the ride is you.

TESTING GROUND

“The first frame was 545 grams. We put it on the test machine and the frame behaved so beautifully—it was so stable. We only had to add 10 grams, and we could test-ride the frame. That was the moment we knew we had discovered something big.”

—Peter Denk, Aethos Engineering Lead

RULES? WHAT RULES?

*Turns out, this bike may be Illegal in some circles. With Aethos, we chased ride quality, not a number, but we know a light, stiff, and balanced bike is magic at the pedals. The result? The lightest disc road frame ever produced with builds as light as 5.9kg, and all with the telepathic handling, response, and stiffness targets you’ve come to expect from every bike we make (*Psst…don’t tell the UCI).

GREATER THAN THE SUM OF ITS PARTS

THE NEW MODERN ROAD BIKE

To say that “everything has been considered with this bike” would be an understatement. We spent weeks upon weeks iterating, designing, and obsessing over every piece of the puzzle. But with the rider at the center of the conversation, our goal was to make a bike that would fit your riding lifestyle—not the other way around.

PERFECTION IS IN THE DETAILS

From dropouts to derailleur hangers, no gram was overlooked. The same can be said about the approach of our partners at Roval Components. They’ve been working towards the same North Star of ride quality, and the 1248-gram Alpinist wheels and new Alpinist bar/stem combo were tailormade for Aethos and the ride of your life.

“HAVE YOU RIDDEN IT YET?”

THE BIG EASY

Before Specialized, there was just a guy named Mike. He loved to ride the roads that traverse the Santa Cruz mountains, and he created a not so facile ride called “the Big Easy”—7000 feet of climbing over 80 miles. It’s become a part of the Specialized DNA, and it’s been a rite of passage long before we won any races. The Big Easy is still the beating heart of the brand today.

THE MOTHER TREE

It should be noted that these photos were shot directly before the CZU Lightning Complex Fire. The Mother Tree as it’s known, at the top of Mt. Madonna Road, is a great landmark for many of the rides coming from the Specialized HQ. Take a jacket, though, as the weather isn’t the same at the top as from whence you came.

CORRALITOS MARKET

Make sure you stop at the Corralitos Market & Sausage Co.—it’s a fantastic spot to refuel before the ensuing climb. Plus, it’s a great place to meet up with your cyclist friends that live on the other side, not to mention that the homemade sausages can’t be beat.

GLORIOUS GRIT

“Having never ridden The Big Easy before, I was optimistically, well, pessimistic about it. It's a dauntingly fantastic ride that throws a little bit of everything at you. By the end of it, the ride will have revealed just what you're made of— glorious grit.”

—Starr Walker, Road Product Manager

FOUNDER’S EDITION

We celebrate every new platform we introduce with a Founder’s Edition. Limited to 300 bikes globally, this Aethos is the lightest build on offer, and it features an exclusive, stunning paint scheme.
