The GiroDisc slotted ring measuring 345x28mm with 10 pin holes and a 54mm annulus is offered as a replacement slotted outer ring. The dimensions and pin-hole pattern define its rotor hat compatibility, while the slotting aids in shedding pad deposits and brake gases to support consistent braking performance during repeated stops. Use where the listed sizing matches the rotor assembly.
