Bianchi Arcadex Pro GRX 820/822 1X12

The Bianchi Arcadex PRO GRX 820/822 Disc 1×12 at Freedom Machine Australia is a high-performance gravel bike designed for riders who seek speed, control, and adventure on mixed terrain. Built around a lightweight Arcadex PRO carbon frame, it combines stiffness and comfort with modern gravel geometry. The Shimano GRX 820 1×12 drivetrain, featuring a 40T crank and an 11–51T cassette, provides a wide range of gears for tackling steep climbs and fast descents. Powerful Shimano GRX 800 hydraulic disc brakes deliver reliable stopping power in all conditions, while Velomann Terbium carbon wheels and 45 mm Pirelli Cinturato Gravel tires ensure traction, stability, and tubeless-ready performance. With clean internal cable routing, a flared gravel handlebar for added control, and a sleek matte finish, the Arcadex PRO GRX is built for both endurance rides and off-road exploration.
