Bianchi Impulso Allroad GRX 810 Disc Gravel Bike 2020
Explore further on a range of terrains on the Bianchi Impulso Allroad GRX 810 Disc Gravel Bike. It's engineered for performance on gravel and other mixed, loose and unpaved surfaces, but won't feel slow on smooth tarmac either. Bianchi has used Triple Hydroformed Technology in the aluminium frame to bring additional strength and responsiveness, and the carbon fork improves handling and compliance.
Shimano's GRX 810 gravel groupset has a wide gear range and shifting is smooth, precise and reliable. The hydraulic disc brakes mean you can stop fast in all conditions for confidence at speed. Rolling on Reparto Corse CDX22 disc wheels with Kenda Flintridge tyres in a road-smoothing 35mm width, you'll get plenty of traction and comfort, alongside speed. With mounts for mudguards and racks, you get additional protection from the elements and be able to pack everything you need for a longer adventure.
