• OMEGA DISC – Sunstar’s highest performance disc
  It is paramount to have absolute braking power and high heat resistance in road races which require hard braking again and again. On top of that, the brake stability in a high temperature range due to repeated hard braking is required in recent years. Sunstar’s OMEGA DISC uses special heat-resistant steel that does not degrade its performance when its surface temperature rises to 650 degrees Celsius. It also has a new floating system that is completely different from the conventional discs, which keeps high controllability even when it stayed at high temperature for a long time. The brake system allows riders to brake with confidence and provides them a great sense of security because it does not degrade its performance even when it is kept in a high temperature range. OMEGA DISC, the crystallization of Sunstar’s technology, plays a role in their sense of security.
