Product Details

Specialized S-Works Crux 5 AXS Gravel Bike

The S-Works Crux 5 gravel bike represents a complete paradigm shift in gravel racing by prioritising real-world speed over simple laboratory metrics. While most brands focus on either aerodynamics or weight in isolation, this machine integrates both into a chassis that weighs a mere 7.1 kilograms. By utilising FACT 12r carbon technology, the frame hits a featherweight 789 grams, allowing you to float over steep climbs while maintaining the structural integrity needed for aggressive descending. This is not just a lightweight bike; it is a precision instrument designed to convert every watt of your output into forward momentum, ensuring that your effort is never wasted on inefficient frame flex or unnecessary bulk.

Engineered for Aerodynamic Dominance

Efficiency in the wind is no longer reserved for the tarmac, and the Crux 5 brings professional road-level aerodynamics to the dirt. Equipped with Roval Terra Aero CLX wheels and a fully integrated Roval Terra cockpit, the bike slices through the air with the same clinical efficiency as a dedicated aero road bike. This integration reduces drag significantly over long solo efforts or when pulling at the front of a lead group. By treating gravel racing as a high-speed discipline where seconds matter, this setup provides the lowest time to finish of any gravel platform ever produced, giving you a distinct mechanical advantage when the pace intensifies on exposed sections of the course.

Unmatched Control and Componentry

The handling characteristics of the Crux 5 are tuned to mirror the responsiveness of the legendary Tarmac, providing a level of agility that feels intuitive on technical trails and loose corners. This surgical precision is complemented by the flagship SRAM RED XPLR drivetrain, which offers wireless electronic shifting that remains flawless even under the coating of dust and mud. Every shift is crisp and immediate, allowing you to maintain your cadence through rolling terrain. For the competitive cyclist who demands the absolute pinnacle of technology, this bike offers the perfect marriage of stability and speed, purpose-built to put you on the top step of the podium.

About Specialized

Innovate or die.

Founded in California in 1974, Specialized began with a simple promise: serious riders deserve serious gear. Half a century later, the brand still funds its own wind tunnel, builds its own carbon, and tests every bike with the world's best so that you ride your own best.

The first production mountain bike. The first cycling-specific shoes. FACT carbon, the Win Tunnel, S-Works. Specialized has a habit of building the things the rest of cycling ends up copying.
