The design of the Shimano XTR RT-MT900 disc brake rotors is a further development of the successful ICE TECHNOLOGIES FREEZA design. While the further weight reduction of 5g and 10g is particularly attractive for the 140mm and 160mm discs, the 180mm and 203mm versions are characterised by a further improvement in heat dissipation of 20°C in intensive tests and are also pleasantly low-weight (203mm: minus 30g).

Technologies
Ice-Tech FREEZA
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.
Center Lock System
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.
