Bianchi Via Nirone 7 Allroad GRX400 Disc Gravel Bike 2021
Made for gravel exploring and tough mixed-terrain commutes, the Bianchi Via Nirone 7 Allroad GRX400 Disc Gravel Bike takes the road less travelled in its stride. Designed to be versatile for both gravel and road cycling, the Via Nirone uses a strong aluminium frameset and carbon fork, combining durability with comfort to be the perfect one-bike option for many riders. The equipped Kenda Happy Medium tyres roll fast on roads and hardpack but pack cornering knobs for all-road confidence. With a 35mm width, they add comfortable compliance, and the frameset even has clearance for up to a 40mm width.
The Shimano GRX 400 groupset is part of their gravel-specific range, offering a wide 10-34t range to ascend even the most strenuous of climbs. Developed for exploring, the levers feature off-road specific ergonomics, and the clutch rear mech provides silent, chain-slap free performance on rough surfaces. For confident descending, the Shimano RX400 hydraulic disc brakes have excellent stopping power, even in wet weather. Bianchi house brand Reparto Corse components keep the cost down without sacrificing quality, ensuring that the Via Nirone is a superb choice for aspiring adventure cyclists.
