Reinventing Round

Meditating on the breathing and swaying of a bike under load in the lab, lead engineer Peter Denk had an epiphany—true performance lies in the shape, not the material. After a few hundred thousand supercomputer simulations, we knew we were right.

Break the Rules

At just 585 grams, the Aethos frame may be too light for the UCI rule book, but when the pros get a chance to just ride, it’s the Aethos they reach for. Ride along with the World Champ as he takes us up his favorite climb on a very special Aethos.

Aethos X 105 Di2

Straddling the line between perfect ride quality and undeniable style, the world’s lightest production road bike now comes with Shimano’s new 105 Di2 12-speed electronic shifting. Whether climbing mountain passes or soaring gorgeous descents, you’ve got the perfect steed to do it all.
