Shimano XTR DURA-ACE SAINT Disc Rotor RT-MT900 Centre-Lock Ice Tech FREEZA 140mm, 160mm, 180mm, 203mm. EXT

The pinnacle in mountain bike braking, Shimano XTR RT-MT900 disc brake rotors deliver superb stopping power for the most aggressive riding. The Ice Technologies Freeza rotors dissipate heat to maintain braking performance on long downhill stretches. Shimano’s Center Lock mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.

Technology
Ice Technologies Freeza
Ice Technologies combined with Freeza disc brake rotor construction rapidly dissipates heat for more consistent braking performance in extreme conditions, longer pad life, and less brake fade and noise.

Benefits and features:

Lightweight clad rotors with heat dissipating paint on exposed aluminum layer segments provide superior cooling, consistent brake performance, and lighter operation under all conditions
Clad brake pads with Aluminum/Stainless fins support rapid heat dissipation which helps reduce maintenance, provide longer pad life, and create less brake fade and noise
Ice Technologies and Freeza provide consistent braking performance with longer pad life, less brake fade and noise.

The lightweight and highly efficient three-layer sandwich structure of stainless steelaluminumstainless steel enhances heat dissipation.

140C reduction in heat (vs stainless steel disc brake rotor).

Reduce more 10C by high heat dissipation paint (equipped: SM-RT900 and RT-MT900).

Center Lock
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.
