The S-Works Crux 5 is a gravel race frame built to go fast everywhere. The FACT 12r frame weighs just 789g, it's the most aerodynamic Crux yet, and it handles loose dirt with the same sharp, confident steering you'd expect from a Tarmac on pavement. Specialized tested it on real race courses, and it has the lowest real-world time to finish of any gravel bike they've made. It keeps things practical too, with a threaded BSA bottom bracket and a UDH derailleur hanger, so it's ready for any drivetrain and easy to work on.
