The carbon monocoque frame prioritizes power transfer and stability at high speeds, making it equally capable on hard-packed gravel, broken asphalt, and long competitive efforts.

With race-oriented gravel geometry and wide tire clearance, Halo balances responsiveness and confidence in technical sections while remaining efficient over distance. It’s designed for riders who treat gravel as a race discipline — not a compromise.

Halo Cˣ Shimano GRX Di2 is a high-performance gravel race bike built for speed on mixed terrain. It is designed for fast gravel riding, racing, and long-distance efforts where efficiency and control are critical.

Shimano GRX Di2 delivers reliable electronic shifting under load, while the integrated cockpit and carbon wheels improve aerodynamics and front-end stiffness.

Built with a Halo Cˣ carbon frameset, Shimano GRX Di2 1x12 drivetrain, Valois HBRD 45 carbon wheelset, Continental Terra Speed 45 mm tires, and Valois C∞ HBRD integrated cockpit. A race-ready gravel setup focused on speed, efficiency, and control.
