The Bianchi Impulso Comp is the entry point into Bianchi’s newly redefined "Gravel Racing" category. While the older Impulso models were often seen as versatile "all-road" bikes, this latest generation has been completely reimagined as a speed-focused gravel machine. It inherits the aerodynamic DNA of the Oltre and Specialissima road bikes, featuring clean lines and a fully integrated cable system that minimizes drag.
Unlike the "Pro" or "RC" versions which focus on ultimate weight savings and vibration damping materials, the Comp focuses on pure performance-to-value. It is built for the rider who wants a fast, reactive carbon gravel bike for competitive events or high-speed fire road sessions, without the price tag of a top-tier racing rig.

Key Technologies
Gravel-Specific Aero Design: The frame uses NACA airfoil tube shapes optimized for the lower speeds and varying wind angles encountered in gravel racing.
GRX 12-Speed Mechanical: The 46/30T crank paired with an 11-34T cassette provides a massive range, with a lower-than-1:1 gear for the steepest dirt climbs while maintaining small jumps between gears for flat-out racing.
Integrated AICR Cockpit: Cables are entirely hidden from the wind and protected from trail dust/mud, entering through the custom stem and into the frame.
Racing Geometry: The Impulso Comp has a shorter wheelbase and steeper head angle than a "touring" gravel bike, making it feel snappy and agile when navigating technical sections or sprinting out of corners.
Pirelli Cinturato Gravel M Tires: These are highly versatile "all-rounders," featuring a knobby tread that works well on everything from loose dirt to muddy singletrack without feeling sluggish on the pavement.
