Specialized Crux 5 Sport GRX 800 | Gravel Bike

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 Specialized 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 across real race courses, real terrain, and real riders. When the goal is the top step, nothing in gravel gets you there faster.
