Bianchi Impulso Allroad GRX400 Bike
Ready To Ride The Gravel
Gravel bikes are truly versatile bikes that can glide efficiently on the pavement and conquer the dirt trails when there’s no more pavement. These bikes are perfect for those who love exploring. The Bianchi Impulso Allroad GRX400 Bike is engineered for multi-surface speed-seekers and adrenaline racers. It has an aluminum frame and full carbon fork that uses 12mm thru-axles on the front and rear. The frame features internal cable routing, flat mount disc brake mounts, a press-fit bottom bracket, and is compatible with up to 700x40mm tires. The frame is also compatible with mudguards and a rear carrier.
The GRX400 version of the Bianchi Impulso Allroad comes with a Shimano GRX400 2×10-speed drivetrain. With a 46/30T chainring combo up front and an 11-34T cassette on the rear, you’ll have no issues climbing hills and riding longer distances on mixed terrain. Shimano BR-RX400 hydraulic disc brakes provide highly reliable stopping power so you can descend under control. Velomann GD24 wheels are paired with Kenda Alluvium tires that perform well on the pavement and hardpack dirt. With the right tires, you can ditch the tubes and turn the tires tubeless for a smoother ride, better traction, and fewer flats.
