Specialized Crux Expert – Uncompromising Gravel Performance

The Specialized Crux Expert is the lightest gravel bike in the world, engineered for pure performance and endless adventure. With generous tire clearance and a race-inspired gravel geometry, it’s built to conquer any terrain with speed, control, and comfort.

Equipped with the latest SRAM Rival XPLR AXS wireless drivetrain, the Crux Expert delivers precise 13-speed shifting, flawless hydraulic disc braking, and a wide gear range for both steep climbs and fast descents. Paired with lightweight and durable Roval Terra C Disc carbon wheels and Pathfinder Pro 2Bliss Ready 700x40 mm tires, it ensures maximum grip, stability, and efficiency whether you’re on smooth gravel or rough backcountry roads.

Ultra-Lightweight – The FACT 10r carbon frame weighs just 825 grams, inspired by the design philosophy of our ultra-light Aethos road bike. The result is a gravel machine that climbs with ease, flies over rough ground, and weighs less than a full water bottle.

Capable – With clearance for 47c tires (700c) or 2.1” tires (650b), the Crux gives you the freedom to take on any route, no matter how demanding. More clearance means more capability, from race-day gravel to multi-day bikepacking.

Responsive – The performance gravel geometry, inherited from the Crux’s legendary cyclocross heritage, blends race-ready responsiveness with all-day comfort. It’s quick on the pedals, smooth in the saddle, and ready for whatever the ride throws at you.
