Bianchi Zolder Pro GRX610 1x12

The Zolder Pro GRX 610 1x12 by Bianchi is a carbon gravel/cyclocross bike designed for those seeking speed, control, and responsiveness on the most demanding terrain. It is born with racing DNA: snappy during accelerations, precise in trajectory changes, and stable when the surface becomes technical, muddy, or rough.

The full carbon frame is designed with specific cyclocross geometries, which prioritize agility and maneuverability in slow, winding sections, but maintain stability and performance when pushing hard on fast dirt roads or during race sprints. It is a bike designed for racing, but at the same time perfect for intense training and fast gravel riding.

The single-chainring 1x12 configuration with the Shimano GRX groupset guarantees ease of use, reliability, and clean drivetrain management even in muddy and dirty conditions. Fewer components, fewer distractions, maximum efficiency.

The full carbon fork contributes to making the front end precise and direct, improving handling feel in technical sections. The integration of the second bottle cage mount on the seat tube, positioned higher up, improves ground clearance and passage over typical cyclocross obstacles.

The Velomann wheels paired with Vittoria Terreno Mix 33 mm tires offer the right balance between rolling speed, traction, and control on compact surfaces, gravel, and mixed sections.

It is the ideal choice for those who want a modern, fast, and race-ready cyclocross bike, but also a lightweight and responsive gravel racing bike.
