The GiroDisc slotted ring sized 332x32mm with 10 pin holes and a 52mm annulus is a replacement outer ring with slotting to assist pad cleaning and gas escape. Its listed diameter, thickness and pin-hole pattern identify the rotor hat compatibility for proper installation. The slotted face supports steadier pad bite across repeated stops when fitted to matching rotor assemblies.
