The S-Works Crux 5 is the fastest gravel race bike Specialized has ever made. It's the lightest and most aero Crux yet, it handles loose ground the way a Tarmac handles the road, and above all it delivers the lowest real-world Time to Finish of any gravel bike Specialized has tested.

The 789g FACT 12r carbon frame is built with SRAM RED AXS XPLR 13-speed and a Quarq power meter, Roval Terra Aero CLX wheels and the integrated Roval Terra cockpit, for a race-ready weight of just 7.1kg (size 56).

Time to Finish

Crux 5 was developed around a single question: does it get you to the finish line faster on the hardest gravel courses on Earth? To answer it, Specialized built the most comprehensive gravel race simulations it has ever run.

The result: Crux 5 is up to 9 minutes 58 seconds faster over Unbound than Crux 4 (based on Sofía Gómez Villafañe's 2025 race, with the same course, conditions and rider input).

Specialized Crux 5 – most aerodynamic Crux yet

The Most Aerodynamic Crux Yet

Crux 5 is the most aerodynamic gravel race bike Specialized has ever made, saving 15.2 watts.

Drawing on lessons from the Tarmac SL8 and decades of aero research, every tube was sculpted for the speeds of elite gravel racing.

Speed Everywhere, All Day

Speed isn't only about peak numbers – it's about holding power and momentum deep into a race. Crux 5 combines telepathic handling and instant acceleration with balanced compliance that reduces fatigue on rough courses.

Rider-First Engineered and now with 55mm tyre clearance, it keeps the legendary ride feel of Crux 4 while adding real aero performance.

Roval Terra Cockpit and Aero Wheels

Roval's new Terra components bring World Tour-level speed to gravel. The Terra Aero wheels combine deep aero rims with the durability that gravel racing demands.

The one-piece Terra cockpit adds aerodynamics and compliance up front, keeping you fast and comfortable over hours of rough ground.
