The Crux 5 is the fastest gravel race bike Specialized has ever made. It's light and aero, 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 Comp build pairs the 897g FACT 10r carbon frame with SRAM Rival AXS XPLR 13-speed, DT Swiss G500 wheels and 45mm Pathfinder tubeless-ready tyres. It's a fast, efficient race bike at 8.89kg (size 56), with room for 55mm tyres when the going gets rough.

Gravel racer on a Specialized Crux 5 – Time to Finish

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.

Riders racing Specialized Crux 5 bikes on gravel

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.

Race-Proven FACT 10r Carbon

Every Crux 5 is built around a FACT 10r carbon frame weighing just 897g, with the same aero shaping, geometry and Rider-First Engineered handling as the S-Works.

Add a threaded bottom bracket, UDH dropout and room for 55mm tyres, and you have a race bike that's easy to live with every day.
