Bianchi Impulso Allroad GRX 600 Disc Gravel Bike 2020
Performance meets Italian flair in the Bianchi Impulso Allroad GRX 600 Disc Gravel Bike. Versatile and capable, this bike excels on gravel, unpaved roads and mixed terrain while not feeling sluggish when you hit smooth tarmac. The aluminium frame uses triple hydroformed technology in the top tube and head tube which brings strength and responsive steering, and when paired with the full carbon fork makes for a stable ride, plenty of compliance and supreme handling no matter how rough the trails.
Shimano's GRX 600 gravel-specific groupset offers a wide range of gears and the power of hydraulic disc braking, increasing control and confidence in all conditions. The tubeless-ready Reparto Corse CXD22 disc wheels and Kenda Flintridge tyres in a 35mm width smooth out the bumps and absorb shock. With clearance for tyres up to 40mm, plus mounts for mudguards and racks, there's plenty of scope to prep your bike for long days and multi-day adventures.
