Black Diamond 12 Groove Discs are engineered and made using Computer Aided Design (CAD) and manufacturing to ensure they are finished to the most exacting standards.
The 12 curved radial grooves on each disc face help dissipate heat and de-glaze the pads, offering greater friction under hard braking condition and making them less likely to fade. The result is better pedal feel and improved brake response.
The unique compound and heat treatment after machining combine to provide awesome braking performance that will improve stopping power and give longer lasting durability.
