The compound
Circo M119.
A carbon-metallic compound built for rally and circuit work, and the standout in the Circo range for short events. It publishes 0.48–0.51 friction from a 50°C floor — near race-compound bite that is already working on a cold first lap. Circo describe it as more forgiving to drive than M127.
