The Specialized Crux 5 Sport is a lightweight gravel race bike built to turn every watt into speed. Its FACT 10r carbon frame weighs just 897g and combines Rider-First Engineered geometry with clearance for tyres up to 55mm, delivering a fast, responsive ride across gravel and mixed terrain.
A mechanical Shimano GRX 12-speed drivetrain provides smooth, reliable shifting across a wide range, while Shimano GRX hydraulic disc brakes deliver confident stopping performance. DT Swiss G500 tubeless-ready wheels and 45mm Pathfinder tyres complete a race-ready setup that's equally capable when the route gets rough.
