The Crux is the lightest gravel bike we have ever developed. It features an exceptionally large tire clearance and a highly athletic gravel geometry. It is not just the ultimate expression of gravel performance; it's your ticket to the world of professional gravel racing. The Crux Expert is equipped with the precise and fast-shifting SRAM Force eTap AXS group with hydraulic disc brakes, lightweight and durable Roval Terra CL Disc wheels, and 2Bliss Ready Pathfinder Pro tires (700x38 mm), which grip well even in challenging terrain. EXTRA LIGHT: The S-Works frame made from FACT 12r carbon weighs only 725 grams, while the standard frame made from FACT 10r carbon weighs 825 grams. We achieved this by applying the revolutionary insights developed from the lightest road bike frame in the world, the Aethos, to the Crux. The result? A gravel bike that climbs beautifully, flies over rough terrain, and weighs less than your filled water bottle in the holder. Versatile: The Crux has a tire clearance of 2.1 inches for 650B wheels and 47C for 700. More tire clearance means more options. Just like our Diverge, the Crux will take you anywhere, carrying full speed. Direct handling: The Crux is nimble, playful, and responsive. Its iconic history in cyclocross has influenced its performance-oriented gravel geometry and competition-optimized riding position.
