Bianchi Via Nirone 7 Allroad GRX 400 Disc Gravel Road Bike 2020
Using a strong aluminium frame and carbon fork, the Bianchi Via Nirone 7 Allroad GRX 400 Disc Gravel Road Bike provides a blend of strength, stiffness and comfort, together with stable handling and responsiveness. There are mounts for mudguards and racks to further improve versatility, and all cables are routed internally, keeping them away from the elements and helping to retain the sleek aesthetics. Sections of the frame utilise hydroformed tubing to add strength where required, and the carbon fork helps to soak up shock for a smoother ride.
Gravel-specific Shimano GRX 400 10-speed components offer a wide range of gears and reliable shifting, plus the power of hydraulic disc braking for performance in all conditions. Practical additions include mounts to fit mudguards in bad weather, and rack mounts for carrying kit on long and multi-day adventures. There's the option to add a bottle cage to the underside of the downtube for carrying more bidons, or simply to keep the main part of the frame free for luggage.

- Shimano GRX 400 gravel groupset with hydraulic disc brakes
