725G FRAME/7.25KG COMPLETE 

Lightest Weight

We took the revolutionary breakthroughs that made Aethos the lightest bike ever and applied them to the Crux. The result? A gravel bike that climbs like a dream and floats over nightmarish terrain with a frame that weighs less than a full bottle in your cage.

HEY LAZY CARBON, BEAT IT! 

Reinventing Round

A “eureka” moment led Peter Denk to reimagine what was possible with carbon and redefine the lightweight road bike with the 585 gram Aethos. When Road and Gravel Product Leader, Stewart Thompson, saw this breakthrough, he knew it would change gravel riding forever. The all-new Crux was born.
