The GiroDisc slotted ring sized 380x35mm with 10 pin holes and a 52mm annulus is a replacement slotted outer ring for rotor assemblies that match those dimensions. The pin-hole pattern and annulus callout identify hat compatibility, while the slotting helps maintain cleaner pad contact and aid gas evacuation, supporting more consistent braking during repeated or demanding stops.
