The Impulso Pro was created for off-road experts who throw everything into their competitive pursuits.

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.

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.
