2027 Bianchi Impulso COMP GRX 610

The new Impulso family is Bianchi's answer to gravel riders seeking speed on any type of terrain, from dirt to gravel, from mud to asphalt. Bianchi's Reparto Corse designed the new Impulso platform to meet the needs of the most competitive gravel riders, those who demand aerodynamic performance, lightweight performance, and off-road versatility from their bikes.

Designed for pure performance, the Impulso frame is intentionally clean and linear, as essential as the frames of Bianchi's latest road models. There are no extra mounts for bags or bottle cages, nor protruding screws that would add weight and aerodynamic drag.
