- Aero-focused gravel race frame
- Shimano GRX 825 Di2

Why it exists
Built for gravel racing, not gravel wandering.
The Bianchi Impulso RC is designed for riders who approach gravel with a race mindset. Instead of treating unpaved roads as slow adventure terrain, it is built for fast sectors, rolling attacks, exposed farm roads, loose corners, steep ramps and long efforts where aerodynamics, handling and efficiency all matter.
This is where the Impulso RC separates itself from more relaxed gravel bikes. The frame language is more purposeful, the component package is more competition-focused, and the overall build is aimed at riders who care about speed as much as versatility. It is a gravel bike for riders who want to stay low, carry momentum, measure their effort and keep pushing when the surface changes.

Why this bike stands out
The Impulso RC blends aerodynamic intent, gravel-specific control and a complete electronic race build for riders who want a faster way across mixed terrain.
Electronic shifting under pressure
Shimano GRX 825 Di2 gives precise 2x12 electronic shifting for rolling terrain, loose climbs and race situations where clean gear changes help preserve rhythm.
Power data from day one
The included 4iiii Precision 3 single-sided power meter gives riders immediate access to wattage-based training and pacing without needing an aftermarket upgrade.
The race build logic
A complete package for riders who train, pace and race with purpose.
At this level, value is about more than one headline component. The Impulso RC GRX Di2 build brings together the pieces serious gravel riders normally prioritize: a carbon race platform, electronic shifting, hydraulic disc braking, fast gravel wheels, race-oriented tires and integrated power measurement.
The result is a bike that feels ready for structured training and competitive riding from the first ride. You are not simply buying a frame and planning a list of immediate upgrades; you are starting with a package already built around speed, control and measurable performance.
Best for
This is the right bike for riders who want performance-first gravel capability, not a utility-focused adventure build.

Ideal for riders targeting fast gravel events, competitive group rides and long race efforts where efficiency and position matter.
Road riders moving to gravel
A strong match for road cyclists who want the feel of a fast bike, but with the tire volume and control needed for loose and broken surfaces.

The power meter makes this build especially useful for riders who pace climbs, manage race efforts and train with structured intervals.
