So Light, It’s a Crime

Complete Builds at Just 5.9kg Thanks to Flow State Design

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. The shape itself delivered stiffness, delivering UCI illegal 5.9kg builds and more responsiveness. The result wasn’t just a more perfect ride, it was a new way of making bikes—Flow State Design.

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

Decades of Body Geometry data, now tuned into a fit that works for more riders than ever.

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.
