Specialized Crux 5 Comp — Wireless Gravel Racing in Obsidian Metallic/Dune White
Eat My Dust
The Crux 5 Comp sits at the sweet spot of the Crux 5 range — pairing the same race-proven FACT 10r carbon frame with SRAM Rival XPLR AXS wireless shifting. Born from the fastest gravel race bike ever made, the Crux 5 delivers the lowest real-world Time to Finish of any gravel bike — validated across real race courses, real terrain, and real riders. The Comp steps up from the Sport with a wireless drivetrain, giving you cleaner cockpit aesthetics and effortless gear changes when the race is on the line.
Finished in a bold Obsidian Metallic/Dune White colourway — dark, purposeful, and built to mean business on the start line.
