Specialized Crux 5 Sport (2027)

Crux 5 is born from the legacy of the fastest gravel race bike ever built. It’s not just the lightest, it’s not just the most aerodynamic: it’s the bike that turns every watt into pure speed, from attacking on climbs to the final sprint on dirt.

Designed for the most demanding gravel races, the Crux 5 combines lightning-fast responsiveness of a road bike with the confidence of a true off-road machine. On smooth dirt it flies like a Tarmac on asphalt, while on gravel, rough terrain and singletrack it remains stable, precise, and always under control.

Every detail is optimized to reduce your actual riding time : race geometry, featherweight construction, advanced aerodynamics, and a frame capable of absorbing vibrations without wasting energy. The result? A real advantage on long routes, gravel marathon races, granfondos, and adventures beyond the tarmac.

If your goal is the top step of the podium or simply being the fastest in your group, no other gravel bike gets you to the finish line as quickly as the Crux 5.
