GiroDisc slotted rotor rings, 355 x 35mm, with 10 pin holes and a 52mm annulus. These slotted rings match 355mm diameter rotors with a 35mm width and a 10‑pin bolt pattern centered on a 52mm annulus. They provide the correct physical interface for compatible hat and hub arrangements and are specified by exact diameter, width, pin pattern and annulus size for direct physical replacement where those dimensions are required.
