Cannondale SuperX Carbon 3 Gravel Bike - 2025

- Shimano GRX 820 groupset

Speed-focused and race-ready, the Cannondale SuperX Carbon 3 Gravel Bike is built to win. With a sub-1,000g frame, advanced carbon construction, and race-proven components, it delivers a fast, responsive ride with the strength and control needed for aggressive gravel racing. From lower drag to increased tyre clearance, every detail is engineered for pure performance and long-haul speed.
Key Features and Benefits:
- Sub-1,000g carbon frame (size 56): This ultra-lightweight frame reduces the overall bike weight. A lighter bike allows for faster acceleration and improved efficiency. The result is quicker climbs and reduced fatigue over long distances.
- Refined carbon layup for stiffness and compliance: The frame balances power transfer with shock absorption. Stiffness helps you maintain speed under load, while compliance softens rough surfaces. This leads to better control and less fatigue during demanding rides.
- Shimano GRX 820 gravel-specific groupset: Built for mixed terrain, it offers crisp shifting and confident braking. You get reliable performance in all conditions. This ensures precise gear changes and control when it matters most.
- Reserve 40/44 GR carbon wheels with DT Swiss 370 hubs: These wheels provide aerodynamic advantage and long-term durability. Paired with wide tyre clearance (up to 48mm rear, 51mm front), they support stable, low-pressure grip. This means better traction, speed, and comfort on rough gravel.
- Integrated cockpit with Cannondale C2 alloy bar and C1 Conceal stem: The setup combines strength and weight savings with a clean front-end profile. Better integration reduces drag and increases handling precision. It helps maintain speed and control in tight racing situations.
- Race-driven geometry and tyre clearance: Geometry is tuned for fast handling with stability. Wider tyre fitment allows for more grip and comfort. This helps you stay fast and focused across loose, uneven terrain.
Built for racers who demand speed over distance, the SuperX Carbon 3 is engineered to perform under pressure. Its aero-tuned design, low weight, and drivetrain efficiency align with the demands of competitive gravel riding. With support for wide tyres and precision handling, it offers the control needed to hold speed on tough courses. Every component is selected to meet the needs of high-speed gravel racing, with minimal compromise.
Ready for race day or fast gravel miles, this bike brings proven performance to the front of the pack. If you're aiming for personal bests or podium finishes, the SuperX Carbon 3 is built to help you get there with speed and confidence.
