Bianchi Impulso Allroad GRX600 Disc Gravel Bike 2021
The Bianchi Impulso Allroad GRX600 Disc Gravel Bike is perfect for those who love to explore, offering the ability to leave your front door and head wherever the ride takes you. With classic Bianchi styling and a carbon fork, the Impulso is designed for all roads - ideal for fire tracks, gravel and rough roads. A full carbon fork dampens vibration from the road, and 35mm tyres add further compliance for total comfort when heading off the beaten track.
With a host of gravel-specific features, the Impulso has durability in mind. For all-weather adventures and gravel touring the frame features mudguard and pannier rack mounting points, making it an excellent choice for those who commute mid-week but explore on the weekends. The Shimano GRX drivetrain was the first groupset specifically designed for gravel use, offering a wide range of gearing and MTB inspired features.
Kenda Flintridge tyres provide excellent grip to inspire confidence on a wide range of terrains, designed to have your back from the road to trail and everything in-between. Powerful Shimano RX400 hydraulic disc brakes are a perfect pairing for the Impulso, quickly stopping the bike in even the worst weather conditions.
