Bianchi Impulso GRX600 Disc Gravel Bike 2022
The Bianchi Impulso GRX600 Disc Gravel Bike has been designed for efficient travel across a variety of surfaces, from tarmac to trail.
The aluminium frame and carbon fork have clearance for tyres up to 40mm wide for extra control, comfort and grip on rough tracks, with the supplied Kenda Alluviums combining on-road efficiency with off-road traction. Mudguard mounts and rear rack fixings cement the bike’s versatility and allow it to be used for commuting just as easily as for exploring the countryside.
Shimano’s mixed GRX 810 / 600 groupset uses a sub-compact, gravel-specific 46/30T chainset to provide a wide range of gears when mixed with the 11-34 cassette and the hydraulic disc brakes add easy stopping power come rain or shine. The Velomann GD24 rims are tubeless-ready, making them ideal for mixed usage and the flared handlebar gives plenty of hand position options for comfort and control.
