Bianchi Impulso Pro GRX600 Disc Gravel Bike 2022
Designed for speed across a variety of surfaces, Bianchi’s Impulso Pro GRX600 Disc Gravel Bike is responsive and efficient.
Despite its robustness, the carbon frame weighs just 1,100 grams, with stiff, oversized tubes in key areas for better power transfer and there is enough clearance to slot in 700 x 38c tyres for great grip and more comfort. The 1x Shimano GRX drivetrain uses an 11-42 cassette to provide a wide range of gears that is well suited to the bike's rapid, all-terrain aspirations and with thru-axles and hydraulic disc brakes, it is easy to keep the bike in line.
16° flare on the handlebar’s drops gives greater stability and control off-road when things get bumpy and the WTB Riddler Comp tyres offer a good balance of speed on smoother trails and grip on looser surfaces thanks to the larger side lugs.
Highlights
- Impulso Pro carbon frame and fork with clearance for 38mm tyres
- Shimano GRX 600 11-speed gravel groupset
- Shimano BR-RX400 hydraulic disc brakes
- WTB Riddler Comp 700 x 37c tyres
