TECHNOLOGIES

• SHIMANO’s ICE TECHNOLOGIES has realized the ultimate clad rotor, incorporating aluminum fins for enhanced heat control. With an increased surface area for heat dispersion, the rotor achieves a 50°C reduction in heat. This in turn generates a 20% increase in braking force durability and a 20% longer pad life.
• The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
