• Small hemispherical concavities on the surface show when it is time to replace the disc; when these cavities are flush with the rest of the braking surface, it is time to replace the disc.
• Optimal heat dissipation.
• Reliability from cyclocross to downhill.
• Long life even in the most extreme conditions.
