The Crux 5 Sport brings the race-validated Crux 5 platform to riders who want a proven, reliable mechanical drivetrain they can maintain anywhere and trust completely on race day. The FACT 10r carbon frame and S-Works FACT carbon fork deliver the same stiff, responsive ride found across the Crux 5 lineup, while Shimano GRX 800 provides confident, precise shifting across a 12-speed 10-45T cassette with the tactile feedback and bulletproof reliability that mechanical shifting is known for. Shimano GRX BR-RX820 hydraulic disc brakes and tubeless-ready DT Swiss G500 wheels round out a build that earns its place on a gravel start line. When the goal is the top step, nothing in gravel gets you there faster.
