Description
Hi, I’m the Bianchi Impulso Pro GRX 820!
I’m a performance-driven gravel bike built for speed, control, and off-road freedom. My carbon frame with fully integrated cable routing (ICR) offers sleek aesthetics and aerodynamic efficiency. Together with my Impulso carbon fork, I provide confidence and precision across all terrain types – from forest trails to alpine gravel.
My Shimano GRX 820 2x12 drivetrain gives you unmatched versatility. With a 48/31T crankset and a 11-36T cassette, you’ll climb steep grades with ease and hold speed on fast flats. My hydraulic disc brakes (Shimano BR-RX820) deliver reliable stopping power, no matter the weather or trail conditions.
I roll on Velomann Terbium wheels wrapped in Pirelli Cinturato™ Gravel H tyres – in a classy tan-wall design that balances grip, durability, and flair. With a D-shape carbon seatpost and a Velomann Mitora 149 Hyper saddle, you’ll stay comfortable even on long and rough rides.
Whether you're bikepacking, racing gravel, or exploring after work – I’m the Bianchi Impulso Pro GRX 820. Let’s make every ride an adventure.
