Shaft designed for maximum strength by decreasing the sections and therefore the weight where the geometry allows it. Built with special case-hardening steel, obtained with latest generation lathes with 3D models and cad/cam technology for maximum geometry control, case-hardened and ground in the areas where maximum precision is required. The lightening holes decrease the mass of the shaft with advantages in terms of inertia and acceleration. They have been created in areas where they do not compromise the strength of the shaft.
Completely renewed in terms of aesthetics, the dimension of the slot for introducing the gear selector has been modified by lengthening it to accommodate the gear selector itself.
It can be used with Malossi and Piaggio sprockets.
