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.
Completely renewed in terms of aesthetics, the dimension of the slot for introducing the gear seòector has been modified by lengthening it to accommodate the spider itself.
It can be used with Malossi and Piaggio sprockets.
