Bianchi Via Nirone 7 All Road GRX400 Disc Gravel Bike 2022
Perfect for riders who enjoy big adventures on mixed terrain, the Bianchi Via Nirone 7 All Road GRX400 Disc Gravel Bike pairs a strong yet light alloy frame with a full carbon fork for a stable ride and precise handling. The endurance-inspired geometry puts the rider in a slightly more relaxed but not too upright position.
Built up with gravel-specific Shimano GRX components, shifting is smooth, and Shadow technology in the rear derailleur is ideal for stability over rougher ground, reducing the chances of chain slap or drop. The combination of 46x30-tooth chainrings and an 11-34-tooth cassette brings a wide range of gears including those to assist you up steep or draggy hills.
Tubeless-ready Velomann GD24 disc wheels and Kenda Happy Medium tyres in a 35mm width help soak up bumps for smoother, more comfortable rolling, and traction is excellent, particularly on hard-packed and grassy terrain.
- The aluminium frame uses hydroformed tubes to produce a stronger and lighter structure
- Carbon fork damp vibrations and increases steering accuracy
- Internal cable routing keeps the aesthetic clean and crisp
- An endurance-inspired geometry places the rider in a comfortable, composed position
- Shimano GRX 400 gravel-specific drivetrain with Shadow technology
- Velomann GD24 tubeless-ready disc wheels
