Aethos 2 Expert - SRAM Force AXS
So Light, It’s a Crime
Aethos began with a moment of human insight: frames “breath” under load. That subtle rhythm revealed how force moved. We fed this into our supercomputer, evolving tubes into sculpted forms. Shape itself delivered stiffness. The result wasn’t just the lightest road bike in its class and a more perfect ride, it was a new way of making bikes - Flow State Design.
Flow State Design
Where Specialized Science Club Meets Machine Intelligence
705 grams FACT 10r Frames
The lightest road frame in its class and our most optimized layup ever.
We’ll Never Make a Bike the Same Way
Aethos redefined how we build bikes. Crux and Tarmac SL8 followed its lead.
Rider First Engineered
Regardless of the bike’s size, every rider gets the famed Aethos ride quality.
Geometry and Fit Perfected for More Riders
We refined the fit and geometry using data from over 100,000 Body Geometry fits to make long days in the mountains feel even better. Climb faster. Descend harder. Ride longer. You get precise handling in a more versatile and confidence-inspiring package.
New Fit for More Comfort and Performance
We increased the stack by 15mm to help take pressure off your hands, neck and shoulders.
More Confidence, More Stability
What goes up, must come down. A 7mm longer wheelbase for confidence to push the pace on descents.
Carve the Corners with Precision
A 0.5° Slacker Headtube creates nimble but intuitive handling. Aethos 2 must be reading your mind.
Ride ‘in’ the bike, not ‘on’ the bike.
With a 3mm lower BB height is optimized for higher volume road tires and a more connected feeling to the bike and road.
More Versatility. More Clearance. No Compromise.
Aethos 2 clears 35 mm tires with ease. That means smoother, faster rides, more grip, and more roads. That kind of upgrade usually comes at a cost. Not here. We didn’t just create our most optimized layup ever, we re-engineered every detail. No gram was safe from the Specialized Science Club’s obsession.
