Bianchi Impulso Pro Gravel Bike 2025

For demanding athletes who throw everything into their competitive pursuits, who race to win in every gravel fondo they enter.

The all-new 2024 Bianchi Impulso Comp GRX is lightweight and aero thanks to its carbon frame with full interal cable routing. Designed to move air smoothly across the Celeste paintwork, the Impulso Comp GRX also features 700x42 tyre clearance and is compatible with 1x or 2x drivetrains.

Clean aesthetics aren't all this bike is about, the 2024 Bianchi Impulso Comp is built to go fast. Taking design cues directly from the their top-level RC models with geometry inspired by XC mountain bikes it's also extremely stable and capable.
