AirCon Brake Disc Ø140mm — Black

3-piece disc: high-performance steel braking surface, aluminum cooling fins, and aerospace alloy spider. The fins are not attached to the braking surface, so they can be reused when changing discs. According to the manufacturer's lab tests, this system reduces the maximum temperature by up to 50°C after one minute of continuous braking and returns to ambient temperature about 20 seconds sooner than a conventional disc — meaning less fade on long descents. 6-bolt (IS) mounting, anodized and laser-etched. 140 mm diameter.
