SpecializedCrux 5 Sport Gravel Bike

The Crux 5 Sport is designed for the purist who demands the speed of the world’s fastest gravel frame paired with the legendary reliability of mechanical shifting. Built upon a FACT 10r carbon frame weighing just 897 grams, this bike inherits the exact geometry and performance characteristics of the elite S-Works models. It provides a lightweight, responsive platform that handles technical dirt sections with the same surgical precision as a Tarmac handles asphalt. By focusing on a power-to-weight ratio that remains highly competitive at 8.94 kilograms, the Sport model ensures that your energy is focused entirely on forward progress, making it an exceptional choice for riders who want a high-performance race bike that is as simple to maintain as it is fast.

Aerodynamic Efficiency and Durable Construction

Achieving the lowest real-world time to finish requires more than just low weight; it requires a bike that can slice through the wind over hours of racing. The Crux 5 Sport utilizes a Rapide stem and an alloy handlebar to create a cockpit that is both aerodynamically efficient and incredibly robust for high-torque efforts. This is complemented by the DT G-500 wheelset, which offers the perfect blend of durability and rolling efficiency required for the unpredictable surfaces found in modern gravel racing. Whether you are navigating deep sand or high-speed fire roads, these components work together to minimise drag and maximise stability, ensuring that your effort is never hindered by your equipment.

Reliable Mechanical Precision and Control

The heart of the Crux 5 Sport is the Shimano GRX 800 mechanical 12-speed drivetrain, a system revered for its tactile feedback and flawless performance in the harshest environments. The ergonomic levers are specifically designed for off-road use, providing secure braking and effortless shifting even when navigating bumpy descents or steep gradients. This mechanical setup offers a wide gear range that allows you to maintain a steady cadence through varied terrain without the need for battery management. When combined with a frame that is validated across real race courses, this bike delivers a dependable and incredibly fast racing experience that empowers you to chase the top step of the podium with total confidence.
