Zusammenfassung:A disk brake disk has a bell made of a first material and a braking band made of a second material. The bell has a bell body having a radially outer bell body portion and forms a plurality of bell projections radially protruding from the radially outer bell body portion. Each bell projection has a projection base close to the radially outer bell body portion and a distal projection portion far from the radially outer bell body portion. A braking band body is coupled to the distal projection portion. Adjacent projection bases are joined to one another by a bell rib made in a single piece with the bell body and having an inner axial rib face and an outer axial rib face. The braking band body is coupled to the inner axial rib face, leaving the outer axial rib face free and externally facing the disk brake disk.
