GEOMETRY CHART
GRAVEL, FASTER.
Reparto Corse set out to re-engineer our Impulso platform to better suit the needs of competitive gravel racers.
Tuned for those who demand the holy trinity of aerodynamic performance, low weight, and off-road capability.
In order to win gravel races, you need a machine that is engineered for the task. The Impulso RC is built to make you faster.
RACING GRAVEL TUNED
Reparto Corse has meticulously optimised the Impulso RC for the demands of the high-velocity, extremely technical discipline of gravel racing.
Treating every facet as part of the cohesive performance whole, this systematic approach is becoming central to Bianchi’s design thinking.
AERODYNAMICS
Lessons learned from the Oltre RC aero bike and our next-generation Specialissima RC allrounder have been applied to the Impulso, along with an integrated fork and specifically crafted aero wheelset, creating one of the most aerodynamic gravel bikes in its category.
The seat post uses a D-shaped profile, allowing for greater comfort in the saddle compared with a perfect NACA profile – perfect for challenging mixed terrain.
ESSENTIAL FRAME
For pure performance, the design of the Impulso frame is kept intentionally clean, inspired by the sleek aerodynamic frames of our road machines.
There are no extra mounts for multiple bag and bottle installation, or protruding screws to add weight or drag.
TOTAL CONTROL
On fast gravel race parcours, you need to have total control. Reparto Corse devoted significant resources to enhancing the cockpit system of the Impulso RC, putting the power to win in your grasp.
COMPETITIVE STIFFNESS
On the re-engineered Impulso, we’ve focused on the stiffness of the cockpit system to achieve a much better racing feel and advanced control.
RIDE WITH FLARE
The 16° flare of the bars helps give the rider extra control on technical downhill sections.
RACING GEOMETRY
The Impulso uses a progressive geometry for the frame. Inspired by the safe, stable performance of elite bikes in off-road racing, it boasts a shorter stem than the Specialissima RC and a longer reach. Confident performance on bumpier sections is provided thanks to the 1,025mm wheelbase.
We modelled multiple bottom bracket drops before settling on 70mm for the revamped Impulso family. This gives the rider maximum control and a more aggressive overall experience.
RACE-WINNING CLEARANCE
The re-engineered Impulso frame can accommodate 42mm tyres, however running smaller sizes will aid in the dispersion of mud when the conditions and course demand it.
RC SADDLE
Great performance at the most advanced professional level. With its aggressive design, the saddle has been engineered to ensure the best aerodynamic position on the bike and maximum power transmission when pedalling.
