Race-Proven Engineering and Cooling Efficiency
Girodisc rotor rings are cast in the USA from a proprietary high-carbon iron alloy designed to withstand extreme heat and repeated high-speed stops. The 72 curved internal vanes act as centrifugal pumps, pulling cool air through the disc to regulate temperature and resist fade. These rings deliver precise pedal modulation and exceptional longevity on both road and track.
