Overview
Crux 5 Frameset
Eat My Dust
The Crux 5 was born from the fastest gravel race bike ever made. Not just because it’s the lightest. Not just because it’s our most aero. Not just because it handles dirt like a Tarmac handles pavement. But because it delivers the lowest real-world Time to Finish of any gravel bike ever made. Crux 5 turns more of your effort into pure speed—validated for real race courses, real terrain, and real riders. When the goal is the top step, nothing in gravel gets you there faster.
