Shimano RT-MT905 Ice Technologies Freeza Dura Ace, XTR, Saint 6 Hole Disc

At the top of MTB braking systems, disc brake rotors XTR RT-MT905 They offer superb stopping power for the most aggressive driving. ICE TECHNOLOGIES FREEZA rotors disperse heat to maintain braking performance on long downhill stretches.

Features

Extraordinary stopping power, smoothness and control for peak performance in the most demanding riding conditions
Maximum heat reduction thanks to the ICE TECHNOLOGIES FREEZA rotor structure combined with a special paint with high heat dispersion
The significantly reduced surface temperature improves braking performance and Luniformity (less efficiency losses), reducing noise and prolonging the life of the pads
The 203mm RT-MT905 operates 100°C cooler than a 220mm stainless steel rotor in the most extreme conditions, with a more compact design

Technologies

Ice Technologies Freeza
ICE TECHNOLOGIES FREEZA rotors use a 3-layer stainless steel-aluminum-stainless steel structure to reduce Lheat accumulation. The inner aluminum layer extends towards LThe interior has a large radiating fin which increases its cooling capacity. The ICE TECHNOLOGIES FREEZA rotors guarantee highly advanced performance, superior to the already extraordinary ones of our ICE TECHNOLOGIES rotors. The fins disperse heat and help keep the temperature lower in extreme conditions to ensure stable braking power, reducing efficiency losses and noise. ICE TECHNOLOGIES FREEZA rotors feature an extended internal layer of aluminum with large radiating fins that increase Lcooling efficiency. Shimano ICE TECHNOLOGIES FREEZA rotors offer an astonishing 100°C reduction in heat buildup compared to standard stainless steel rotors and a 40℃ reduction compared to our ICE TECHNOLOGY rotors. Furthermore, the fins of our high-end rotors are coated with a special high heat dissipation paint on the fins which can further reduce L'heat accumulation of 10°C.
